AB  - Large number of studies analyzed physical and mechanical properties of high-volume fly ash concrete, but only a few discussed its structural behavior. Material properties are an important input parameter for structural analysis, but they are insufficient for reliable conclusions to be made. This study analyses flexural behavior of reinforced concrete beams made with 63% of low-calcium class F fly ash in total cementitious materials mass, using experimental method and analyzing current code predictions (EN 1992-1-1). The analysis was done by comparing beams made with two longitudinal reinforcement ratios, made with traditional cement concrete (OPC) and high-volume fly ash concrete (HVFAC), both corresponding to concrete class C30/37. Beams were tested in a four-point bending test measuring vertical displacement, crack development, concrete strains and longitudinal reinforcement strains. According to this research, the flexural performance of HVFAC beams is similar to flexural performance of corresponding OPC beams in terms of ultimate bending capacity. The significant difference was noticed regarding cracking extent that was higher in HVFAC beams. Available ultimate bending moments code predictions can be applied on HVFAC beams with similar precision and variation of results, like for OPC beams. However, this cannot be concluded for parameters depending on the cracking behaviour, like cracking moments or deflections. Results and analysis presented in this study indicate that HVFAC can be used in structural elements subjected dominantly to bending, like beams and slabs. More research regarding structural behavior of HVFAC using full-scale long-term tests is needed to develop larger database for reliability analysis.

AB  - Producing limestone powder requires comparably far less energy than the production of ordinary
Portland cement (OPC), making it a promising sustainable solution for partial replacement of OPC
in concrete. Lower production energy could be translated into lower environmental impact and
lower cost, which are two pillars of the sustainability of the resulting concrete. However, the
question remains if replacing OPC with larger percentages of limestone powder would compromise
the performance of the resulting concrete to a level that surpasses the environmental and
economic gains. In order to assess the collective impact of these concretes, a performance-based
multi-criteria decision analysis framework, ECO2, is used. For that purpose, 26 experimentally
verified, concrete mixtures with and without limestone powder were evaluated through potential
application in two types of reinforced concrete (RC) structural elements (slabs and columns)
under identical environmental condition. The main results of the research showed a clear environmental advantage of concrete with a reduced OPC content, but the relatively higher superplasticizer amount in some cases could affect the final sustainability performance of the resulting mix. In the case of RC slabs, the best ECO2 score was obtained for concrete containing limestone powder. Mixtures with 200–250 kg of cement per unit volume of concrete had the highest ECO2 score for all the considered criteria. In the second case, due to the nature of the structural performance requirements in columns, the crucial influence of the concrete compressive strength is clear. The obtained results have shown approximately equal sustainability potential of OPC and limestone concretes in vertical elements such as columns. However, it seems that a certain improvement in the design of concrete mixtures with a high limestone powder content could
make these competitive in all fields.

AB  - In the course of XX century, the knowledge on the properties, preparation methods andthe possibilities for the application of lime mortars has been lost to a large degree. However, duringthe last three decades these materials have been used in the reparations and restorations of historicalbuildings, both for their compatibility with the existing mortars used for building and rendering, andfor their favorable physico-mechanical properties.Locally available component materials were chosen for the purposes of this dissertation, with theaim of preparing the mortars compatible with lime mortars that were used for rendering on theterritory of Serbia until the first half of XIX century. The lime putty, aged for six months, and riversand “Dunavac” were used as binders in two different fractions: with larger grains (0/4 mm) andwith smaller grains (0-0,5 mm) in all the investigated mortars examined within the experimental partof work.In the first part of the experiment were investigated two groups of mortars: the mortars in which thelime was partially replaced with natural zeolite and the mortars in which the river sand was partiallyor completely replaced with crushed brick. These mortar types were prepared for two lime/aggregateratios, 1:3 and 1:1 (volume), using two types of care. Investigations were performed on 19 mixturesin total, in fresh and hardened states, at different ages (mainly hydrophysical, microstructural andmechanical properties).In the second part of the experiment durability tests (resistance to the effects of frost and solublesalts) were performed. It has been shown that both additions that were used, when the mortarswere cured in the humid environment, affected the strength increase with the pressure increase,total porosity and the coefficient of capilary absorption. Both additions induced changes in the limemortars microstructure. It was concluded that the suggested method of preparation of compositesamples was adequate for performance of investigations of the durability of these materials.

AB  - It is estimated that by the end of the current decade, about 26% of clinker will be replaced by suitable alternative materials, among which limestone filler probably has the greatest potential due to its wide availability and relatively low price. Although codes allow as much as 35% of clinker to be replaced by limestone filler, the amounts used in practice are far less and average only 6-7% globally, with no growth trend over the past ten years. In order to use the great potential of fillers, it is necessary to know the key parameters that affect the properties of green concrete with low cement and high filler content in fresh and hardened state. For that purpose, a total of 18 concrete mixtures were designed, in order to analyse the effects of the percentage of cement replacement, water-cement ratio, but also the particle size of the applied filler. The results of experimental research show that at the same w/c ratio there is an increase in compressive strength with increasing percentage of cement replacement and that it is possible to make medium-strength concretes with a significantly reduced amount of cement (180 kg/m3) compared to traditional concretes. In this way, economic benefits can be achieved, but also the negative impact of the cement industry on the environment can be reduced. Unfortunately, the workability of such mixtures can be impaired to the extent that their practical application is prevented, so it is necessary to take further steps to solve this problem.

AB  - The use of recycled concrete aggregate (RCA) for the production of new concrete can be a promising eco-efficient solution. However, replacement of natural aggregate (NA) with RCA influences concrete’s durability performance. One of major durability problems worldwide is carbonation-induced corrosion, given that a large number of infrastructural objects are exposed to a CO2-rich environment. There are many factors that affect carbonation process, but possibly the most important one is the appearance of cracks in reinforced concrete (RC) structures. Currently, the cracks have not yet been considered as a parameter in carbonation model which is used for defining the service life of RC structures. The objective of this research was to analyse the influence of cracked concrete cover as a good reinforcement protection. In order to ensure a sustainable application of recycle aggregate concrete (RAC), an analysis was performed on RAC with 100% replacement of coarse NA with RCA. The analysis was carried out using own experimental results and the application of existing fib Model Code 2010 carbonation depth prediction model derived for NA concrete. For that purpose, prismatic RC samples without cracks and with different crack width (0.05 mm, 0.10 mm, 0.15 mm, 0.20 mm and 0.30 mm) were made and subjected to accelerated carbonation. The compressive and tensile stress influence on carbonation resistance was evaluated as well as reinforcing bar corrosion at crack position. The conducted analysis showed that even with low crack widths (0.05 mm) the maximum carbonation depth was significantly higher compared with the uncracked samples. The results showed that compressive stress increase had no significant difference in the carbonation depth of samples.

AB  - This study analyzes the feasibility of valorizing industrial by - product, fly ash from a thermal power plant as a partial replacement of mineral filler - limestone for the production of self-compacting concrete (SCC). Three types of SCC mixtures with different portions of fly ash and the reference mixture with limestone were designed. The synthesized SCCs in the fresh state were examined for density, entrained air content, flowability (Slump flow, Slump flow time (t500), V-funnel time (tv)), passing ability (L-box), and segregation resistance, while hardened state testing included: density, compressive and flexural strength, static modulus of elasticity, water permeability, resistance against freezing in the presence of de-icing salt, and SEM analysis. Taking into account the obtained results it can be concluded that the addition of fly ash has a positive impact on the concrete properties and that the optimal content of fly ash is 20 % with respect to the total filler mass.

AB  - The thermomechanical properties of the bio-fiber composite, as material for the production of thermal insulation panels, were evaluated. The observed mixtures were composed of Miscanthus X giganteus bio-fibers, mineral binders (cement or lime), pozzolanic materials (zeolite and fly ash), and water. The favorable heat transfer behavior of composites based on Miscanthus X giganteus bio-fibers was already affirmed by literature data of similar natural bio-fiber materials, the author’s previous experimental results, and consideration of dynamic heat transfer processes in the insulated outer wall exposed to variable ambient conditions. The experimental assessment was focused on the bearing capacity (i.e. compressive and flexural strength), water absorption, and durability (i.e. resistance to freeze-thaw and carbonation), because there is scarce literature data regarding these properties, whose thorough understanding and systematization are highly important for a wider application of biomass-based thermal insulation materials. The obtained results were evaluated through the comparison to published data from similar bio-based thermal insulations, as well as from conventional thermo-insulation materials such as polystyrene and stone or glass wool.

AB  - Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea
of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore chemically inert and to compare the properties of produced concrete samples. Fresh concrete properties included: slump-flow, t500, V-funnel time, L-box ratio, segregation ratio, density, and entrained air content. Hardened concrete was tested for compressive, flexural and bond strengths, ultrasonic velocity, dynamic elasticity modulus, dynamic Poisson’s ratio, and microstructure. Flowability and segregation increased, while bulk density, compressive and flexural strength, dynamic elasticity modulus and ultrasonic velocity slight declined. Times t500 and V-funnel time, L-box ratio and entrained air changed insignificantly. Considering that all properties should remain or improve in case of waste valorization and the criteria should set to satisfy requirements for SCC, this study proved that all mixtures can be used for structural applications.

AB  - The  use  of  Reclaimed  Asphalt  (RA)  into  new  asphalt  mixtures  becomes  an  inevitable  step  for  sustainable  infrastructure.  Saving natural,  non-renewable materials, such as bitumen and aggregates, the asphalt industry is moving forward with more recycling. Although asphalt is a 100% reusable material, high recycling rates are not yet easily achievable due to many limitations, going from technical specifications through RA properties to asphalt plant capabilities. The  rate  of  RA, which  may  be  used  within  a  new  asphalt  mixture,  depends  on  many aspects: variability, moisture and fines contents, presence of polymers, brittleness of aged binder, etc. The latter is directly linked to the degree of the RA binder ageing. As higher RA content increases the asphalt mixture stiffness, the material becomes more brittle and prone to cracking. The use of recycling additives is  taking recycling to the next level by solving these issues. With the growing  need  of  the  industry  for asphalt  recycling  agents,  many  products  have  appeared on the market with different effects. In this study, three asphalt recycling agents (two industrial and one alternative) were used as rejuvenators.  Blends with50% of rejuvenated RA binder (RAb) and virgin binder were subjected to different ageing levels: short (RTFOT), long (PAV for 20h) and prolonged (PAV for 60h). After each ageing level, physical, rheological and chemical properties were evaluated addressing the ageing behaviour of the additives used. Testing results showed that one industrial additive lost almost all its properties after prolonged ageing, while the other additives showed comparable results with the second industrial product.

AB  - This research was conducted in order to evaluate the influence of different curing conditions on rheological and mechanical properties of high volume fly ash concrete (HVFAC) in comparison with the ordinary Portland cement concrete (OPC). Four types of concrete were made: two HVFAC and two OPC designed to have the same consistency and 28-day compressive strength for samples cured in water. Also, three different curing regimes were chosen: standard water curing (W), standard laboratory air curing (L) and curing in standard laboratory conditions using curing compound based on the polyolefin emulsion (C). The main objectives were to evaluate the influence of these curing regimes on the compressive strength, flexural tensile strength, modulus of elasticity development over time, water permeability of concrete and concrete shrinkage. The use of curing compound improved previously mentioned properties in some extent compared with the samples cured in standard air conditions.

AB  - This study investigates the feasibility of using recycled concrete aggregate (RCA) as a partial substitution of natural aggregate in pavement engineering. Despite RCA’s good properties, such as polishing value and freeze-thaw resistance, its use is limited by low resistance to fragmentation and high-water absorption. This paper parent the experimental results of mineralogical-petrographic and physical-mechanical properties of RCA, natural stone (dolerite) and their combination (RCA content—15%, 30%, 45%, and 60%). The tested granular mixtures showed good resistance to fragmentation and wear (LA 22–27%, MDE 14–15%), as well as satisfactory Polished Stone Value of 55–57, which means they can be used in different layers of pavement structures. According to the obtained testing results, the application of RCA is possible in different flexible and rigid pavement layers and for various traffic loads.

AB  - The need for road (re)construction materials is constantly growing. At the same time, there
is a limited quantity of new, high-quality materials available and a buildup of secondary/recycled
construction materials. One possible solution may be the use of recycled concrete aggregate (RCA) in asphalt mixtures instead of natural aggregate (NA), which also promotes economic and environmental sustainability. The potential use of fine and coarse RCA in road asphalt mixtures is analyzed in this work. Nine asphalt mixtures were tested for base course layers, where RCA was used as a NA substitute. The impact of the quantity of RCA (up to 45% by mass) on the resulting physical and mechanical properties of asphalt mixtures was investigated, and consequently compared with the properties of a reference control mixture produced with NA only. Results reveal that the addition of RCA requires higher bitumen in comparison to the control mixture (up to 1%). Consequently, mixtures with RCA had 15-20% lower stiffness and up to 26% higher critical fatigue strain value (E6). Although RCA mixtures contained more bitumen, their low-temperature resistance was slightly inferior compared with the control mixture (failure temperatures were up to 4.3 C higher). In conclusion, asphalt mixtures with up to 45% RCA can be used without substantially reducing performance.

AB  - In comparative Life Cycle Assessment (LCA) of concrete structures it is of crucial importance to provide the functional equivalence of compared alternatives. Most commonly, the comparison is performed between the structures made of conventional and green concrete mixtures. Since they have different mechanical and durability properties, corresponding structures have different strength and service life. While resolving this problem, two approaches are generally possible: either correction of the functional unit volume or correction of the calculated environmental impacts with compressive strength and duration of service life, if functional unit has the same volume. In this work, in order to assess the effect of service life modeling in LCA, both approaches were tested. As a demonstration, comparison of both slabs and beams made of conventional and high volume fly ash concrete exposed to carbonation was carried out. LCA was performed for 94 different mixtures from reported experimental research and calculated environmental impacts (climate change, acidification, eutrophication, photochemical-oxidant creation, and abiotic depletion of fossil fuels) for both approaches were compared. Results showed that different modeling of service life in LCA can result in totally different, even opposite conclusions. With slightly larger volume of functional unit (7%–20%), all normalized environmental impacts of high volume fly ash concrete structural members were lower for an order of magnitude (6–7 times) compared to those obtained on the basis of the same volume approach. Therefore, drawing conclusions only on the basis of service life modeling with the same volume approach may be misleading. The proper choice of the best alternative should be based on the integrated assessment which includes structural, environmental and cost assessment of the structure as a whole.

AB  - Two alkali-activated mortars with different solid prime materials were analysed. The first mortar contained fly ash, had lower density, higher water absorption, lower compactness, lower compressive strength, similar flexural strength and was less brittle than the second one with fly ash + slag.
The addition of hemp fibres slightly changed the mortars’ density, water absorption, compressive and flexural strength, however significantly increased its energy absorption capacity.
The initially more brittle matrix exhibited significantly higher relative toughness increase. The smoother and less porous fibre/matrix interface assured through numerous fibre/matrix contact points a more optimal fibre/matrix interfacial bond- and frictional stress transfer.

AB  - The lack of understanding the mechanisms governing the interaction between reclaimed asphalt binder (RAb)1 and recycling agents is one of the technical issues that still need to be resolved when high amount of reclaimed asphalt (RA)2 is used in a new recycled asphalt mixture (RAM). Due to important role of RAb in that interaction and increased used of RA, it becomes necessary to have a way to classify RA, as any other material used in asphalt mixture production. It is very important to determine how much RAb is active by itself (DoA)3, but also to determine how much RAb can be considered available for a mix design of RAM (DoAv)4 when a recycling agent is used. Finally, since that RAM’s properties are strongly dependent on the degree of blending between RAb and recycling agent (DoB)5, it should evaluate to what extent RAb contributes to the final properties of RAM. These blending parameters (DoA, DoAv and DoB) are so crucial that identifying suitable methodologies for their assessment would be extremely important in performing a proper mix design due to dangerous of having a lack of active bitumen in RAM. This paper presents a literature review of methods which have been used for the evaluation and assessment of mentioned parameters, grouped in four macro-areas: mechanical, chemical, visualization and mechanistic approaches. Furthermore, summarized review of used methods was prepared together with their critical review, all with aim to find appropriate methods for determining these parameters.

AB  - In reinforced concrete (RC) structures carbonation induced corrosion is one of the biggest durability issue. There are many factors that affect carbonation process (CO2 concentration, relative humidity, temperature, curing conditions and concrete porosity). Probably, the most important factor that affects carbonation process is the appearance of cracks on RC structures. With relatively low concrete tensile strength, cracks are almost inevitable. According to the current state of the art, the cracks have not yet been considered as a parameter in carbonation depth prediction model which is used for defining the service life of concrete structures. The main objective of this research is to analyse the influence of cracks on concrete carbonation resistance using own experimental results and the application of available prediction models regarding carbonation depth. For that purpose, prismatic RC samples without cracks and with different crack width (0.05 mm, 0.10 mm, 0.15 mm, 0.20 mm and 0.30 mm) were made and subjected to accelerated carbonation. The accelerated carbonation tests were performed during 28 days at a CO2 concentration of 2%, relative humidity (RH) of 65±5% and a temperature of 20±2°C. The conducted analysis showed that even with low crack widths (0.05 mm) the maximum carbonation depth was significantly higher compared with the uncracked samples. In all cases, the cracks behaved as an additional exposed surface through which the CO2 molecules were diffused perpendicularly to the crack wall. The crack impact area was approximately the same regardless of the crack width. Further than 10 mm, the carbonation depths remained constant. Also, with decreasing the length at which the average value of the carbonation depth was calculated (averaging length), the mean carbonation depth increased. Finaly, the ratio between the calculated carbonation depths (according to fib-Model Code 2010) of cracked and uncracked samples was up to three times.

AB  - Carbonation resistance of fly ash concrete (FAC) and recycled aggregate concrete (RAC) has been extensively tested in the past decade, but there are still no recommendations for their application in codes of practice. Therefore, the main objective of this study was to determine the minimum concrete cover depth of RAC and FAC exposed to carbonation to satisfy the required service life. In this study the relationship between concrete compressive strength at 28 days (fcm) and inverse effective carbonation resistance (R–1ACC) was established. The analysis was carried out on all data available in the literature in order to establish this relationship for FAC and RAC made with different replacement percentages. After establishing a relationship between R–1ACC and fcm, a prediction of the service life was made using the fib-Bulletin 34 (2006) prediction model for all exposure classes to carbonation. For same concrete class, it can be concluded that in the case of RAC there was no significant difference in the duration of the service life compared with natural aggregate concrete, even at 100% replacement of natural aggregate with recycled ones. For concrete up to 35% of fly ash in total cementitious materials, concrete cover for satisfying the required service life of 50 years was 40% higher compared with Portland cement concrete, and more than two times higher in case of concrete with 40–70% fly ash.

AB  - Since lime renders have slow development of strength, especially in conditions of increased humidity, different types of additions were often used trough history, in order to improve their resistance and durability. This paper presents the effects of locally produced fine crushed tile aggregate addition on physical and mechanical properties of lime-based coating, representing final outer layer of traditional renders, both in normal and increased humidity conditions. This aggregate has been used as partial replacement of natural river aggregate, with granulation 0/0,5 mm in amount of 25, 50, 75 and 100% by volume. Flexural and compressive strength, capillary water absorption, ultrasonic pulse velocity, dynamic modulus of elasticity and open porosity were tested on prismatic samples at the ages of 14, 28 and 60 days. Results show the positive effects of crushed ceramic addition at all ages, especially for the samples cured in humid conditions.

AB  - The use of Self-Compacting Concrete, as a concrete that enables placing without compaction equipment, provides a range of benefits for the contemporary civil engineering practice. The ecological aspect, through possibility of using recycled aggregate obtained by grinding C&D waste concrete, is presented in the paper. The results of physical and mechanical experimental investigation of three concrete mixtures are presented. Besides the reference mixture, two more mixtures were made, prepared with recycled concrete aggregate. One mixture contained 50% mass replacement of coarse river aggregate with recycled concrete aggregate, and in the other one the total mass of coarse aggregate consisted of recycled concrete aggregate of the appropriate size. These series were designed using the Two Stage Mixing Approach (TSMA). Fresh mix tests included: measurement of density, slump flow test, V-funnel and L-box tests. Compressive, flexural, splitting and bond (pull-off) strength were determined on the hardened concrete. Tests proved that all the mixtures showed good properties, encouraging the possibility of the recycled concrete aggregate use for production of proper SCC.

AB  - The aim of this article is to review the utilization of various types of waste in geopolimerization
technology processes. The geopolymerization represents a process comprising of the dissolution of aluminosilicate solids in a strongly alkaline medium followed by condensation of free alumina-silica oligomers to form a tetrahedral polymeric structure. Advantage of this technology represents the possibility of utilization of any silica and alumina-containing waste material that could be dissolved in an alkaline solution. Production of geopolymers from waste not only provides less raw material consumption but also addresses issues regarding the disposal of wastes. Fly ash, red mud, construction and demolition waste (C&DW), slags, or mine waste are the most utilized waste types in combination with supplementary waste materials according to their characteristics. Conducted investigations showed that the use of various waste materials leads to the production of geopolymers with a broad range of final properties. Despite a high number of published Publications and patents, the large-scale utilization of waste is still missing.

AB  - The production of durable concrete with a high content of supplementing cementitious materials and recycled aggregate presents a step towards sustainability in the concrete industry. The paper presents the findings of the study, conducted on four series of concrete with self-compacting properties, which embodied recycled concrete aggregate, as a substitution for natural sand and gravel. Besides, this concrete possessed high content of fly ash, therefore qualifying as ecological (green) one. Particle packing method was used in the design of this concrete. Fresh properties included: density, slump flow, V-funnel, L-box and temperature, while compressive and tensile strengths were evaluated in the hardened state. Although certain difficulties in the application were recognized concerning the fast loss of workability in the fresh state, all of the tested mixtures exceeded the requirements of hardened structural concrete.

AB  - Establishing a wind park presents a complex enterprise, which involves numerous activities, often impossible to synchronize and drive into the appropriate time-frame. Therefore, in some cases, based on reasonable suspicion, a concern arises regarding the quality of already built components of structures. In such cases, the launch of suitable assessment procedures is required. Standards then define proper methods of in-situ assessment of concrete quality. Statistical methods are implemented in the analysis of the concrete components following the strict rules which, if executed correctly by the well-trained personnel of accredited institutions, provide exact and valid insight into the situation. This paper aspires to describe such a procedure on the basis of thorough in-situ investigation and the subsequent analysis. In this study, a large number of 255 core samples were taken from 17 wind tower concrete structure elements – foundations (out of 57 wind towers in total), and the compressive strength of already placed concrete was evaluated based on this set of results. The compressive strength is proved to be a good parameter for evaluating other aspects of concrete quality, mechanical properties, and durability.
