AB  - The efficient way to mitigate the impact of the concrete industry on climate change is to reduce the clinker content in the concrete mix. Beside incorporating supplementary cementitious materials (SCMs), it is possible to use high filler content combined with concrete mix optimisation. Limestone powder emerges as a promising filler mineral due to its availability and ready-to-use technology. In this work, the carbonation resistance of concrete with a high limestone powder content (45–65% of the powder phase) was experimentally tested. Test results showed that, with an optimized mix design featuring low water content and increased paste and plasticizer volume, concrete mixes satisfied high workability and strength demands for commonly applied strength classes. However, carbonation resistance remains a challenge. After two years in indoor natural conditions, carbonation depths were 8%, 28%, and 67% greater than referent Portland cement concrete for mixes with 47%, 58%, and 65% limestone powder content, respectively. Further analyses showed the inapplicability of the existing fib Model Code 2010 service life prediction model to limestone powder concrete. Based on a comprehensive database of experimental results, the modification of the fib prediction was proposed. A full probabilistic service life analysis revealed that for concrete with more than 20% limestone powder content and for both 50 and 100-years’ design service life, the currently prescribed concrete cover depths in European standards should be increased, depending on the carbonation exposure class.

AB  - The environmental impacts of activities such as raw material extraction, construction
of infrastructure, and demolition, place construction as one of the
sectors that exert the highest pressures on the environment, society, and economy.
Some of the major environmental impacts for which the construction
industry is responsible are mineral resource depletion, greenhouse gas emissions,
and waste generation. Among the different strategies that exist to
decrease such impacts, recycling demolition waste into recycled concrete
aggregates has been considered a promising alternative. As such, at present,
the literature dealing with the impact assessment of recycled aggregate concrete
structures is very extensive. Therefore, the objective of this article is to
present a critical view of the state-of-the-art in terms of sustainability assessment
of recycled aggregate concrete structures, taking a holistic perspective by
considering environmental, social, and economic impacts.

AB  - One of the paths to CO2 emissions reduction in the concrete industry is to use low-clinker cements, providing at the same time the performance of concrete that is adequate for application in concrete structures. This paper explores the impact of the clinker replacement with high amounts of limestone powder (21–70% in the powder phase) on concrete carbonation resistance. To quantify this impact, the empirical relationship between the carbonation resistance and the compressive strength of the high-volume limestone powder concrete (HVLPC) was established. For that pur-pose, the regression analysis was applied on the experimental results collected from the published research. The service life analysis based on the full probabilistic approach was performed using the fib Model Code 2010 prediction model and proposed empirical relationship. The first-order relia-bility method (FORM) was applied to solve the limit state function of reinforcement depassivation with a reliability index equal to 1.3. The obtained minimum concrete cover depths were 40–110% higher compared to those prescribed in the current European standard EN 1992-1-1:2004 for in-dicative strength classes. Based on the full probabilistic analysis, recommended cover depths are given for all carbonation exposure classes, commonly applied concrete strength classes, and service lives of 50 and 100 years.

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.

Within the study, member boundary conditions, ambient conditions (relative humidity), reinforcement ratios, and quasi-permanent–to–design load ratios (as per the Eurocode framework) are varied. Through the analysis, the change in deflections is observed relative to the substitution ratio of RCA (from natural aggregate concrete, NAC, to RAC with 100% of coarse RCA) and span-to-effective depth ratio (L/d). The results of the analysis enable a clear overview of the variability of the deflections of RAC members relative to NAC.

AB  - Due to the extremely large global production and utilization of concrete, the concrete
industry is considered a large consumer of energy and natural resources and one
of the main sources of greenhouse emissions and waste generation. Reducing its
impacts on the environment is one of the most important paths toward sustainable
construction development. Replacing cement and natural aggregates with byproducts and waste from other industries is one possible way of achieving this goal.
On the other hand, the disposal of industrial waste, which arises from the pyrometallurgical process of copper production, presents a significant environmental load in
many developed countries. Research performed so far has shown that concrete
made with aggregate obtained from cooper slag instead of natural aggregate can
be produced with good physical-mechanical properties for various applications. In
this work, a cradle-to-gate Life Cycle Assessment of several concrete mixtures
where part of the coarse natural aggregate was replaced with copper slag aggregate
was performed. The conducted case study was based on Serbian LCI data and local
conditions in the vicinity of the town of Bor in Serbia. Results showed that such
concrete mixtures can bring environmental benefits regarding natural aggregate
preservation and waste reduction if the transport distance of copper slag aggregates
is smaller than 20 km. Therefore, from the environmental protection point–of-view,
local application of such concrete is recommended.

AB  - This paper presents an experimental research of one type of green concrete in which Portland cement was replaced with two types of limestone filler of the same origin and mineralogical composition, but with a different fineness of particles. Ten concrete mixtures were designed in which 0%, 15%, 30% and 45% (by mass) of cement were replaced with filler. The water to cement ratio for each mixture was constant (w/c=0.54), and the water to powder ratio was decreasing with increasing cement replacement. Particle size distribution was selected using Funk and Dinger, as well as using Fuller's model. The results showed that it is possible to increase the compressive strength of concrete by reducing 45% of cement, but further research should be focused on improving the workability.

AB  - Modern society has the moral obligation to manage energy wisely, in order to preserve the
environment for future generations. The need for cement implies the extremely high use of relatively expensive energy, evident in all segments of production and application. The use of fossil fuels during cement production is the main problem for creating the greenhouse effect and climate change. Until the end of this decade, about 10% of total CO2 emissions of anthropogenic origin will be a consequence of cement production. In order to preserve the competitiveness of concrete as the most widely used building material, it is necessary to take appropriate actions to promote sustainable development. In that way, a cement replacement with a cheaper and cleaner product – filler could have a significant global contribution. The conducted analyses shown in this paper undoubtedly provide the great potential of green concretes with low cement and high filler content in structures.

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  - With increasing construction activity and concrete consumption globally, the economic,
environmental, and social impacts of human activities continue to increase rapidly. Therefore, it is
imperative to assess the choice and construction of each structure and structural component from a
sustainability-based perspective. In this study, such a multi-criteria decision-making approach using
the MIVES method is applied to the choice of grouped continuous flight auger (CFA) piles. Different
alternatives of CFA piles are studied: length (10 and 20 m), reinforcement (steel cage reinforcement
and structural fibers), and aggregates (natural crushed aggregates and recycled aggregate concrete
sourced from stationary and mobile recycling plants), based on experimentally verified mix designs.
All alternatives were analyzed considering economic, environmental, and social requirements, using
a decision-making tree with eight criteria and eleven indicators, with weights assigned by an expert
panel. The results of the analysis showed a clear advantage in terms of all three sustainability
requirements for CFA piles with steel fibers and recycled aggregate concrete, with all solutions with
steel cage reinforcement having significantly lower values of the sustainability index. Such results
demonstrate the need for implementing innovative solutions even in structural members such as
CFA piles that are often considered in insufficient detail.

Several types of green concrete mix designs were investigated: recycled aggregate concrete (RAC), high-volume fly ash concrete (HVFAC), alkali activated fly ash concrete (AAFAC) as well as their combinations. Numerous tests on material physical, mechanical and durability related properties were conducted as well as sustainability assessments of the structural use of such concretes. Structural behavior under short and long-term loading was investigated on full-scale reinforced concrete beams and recommendations for the design of structural members including strength, serviceability and durability were proposed.

AB  - Recycled aggregate concrete (RAC), i.e., concrete produced with recycled concrete aggregate
(RCA) has been heavily investigated recently, and the structural design of RAC is entering into
design codes. Nonetheless, the service load deflection behavior of RAC remains a challenge due to
its larger shrinkage and creep, and lower modulus of elasticity. A novel solution to this challenge
is the use of layered concrete, i.e., casting of horizontal layers of di erent concretes. To investigate
the potential benefits and limits of layered concrete, this study contains a numerical parametric
assessment of the time-dependent sustained service load deflections and environmental impacts of
homogeneous and layered NAC and RAC one-way slabs. Four types of reinforced concrete slabs were
considered: homogeneous slabs with 0%, 50% and 100% of coarse RCA (NAC, RAC50 and RAC100,
respectively) and layered L-RAC100 slabs with the bottom and top halves consisting of RAC100 and
NAC, respectively. In the deflection study, di erent statical systems, concrete strength classes and
relative humidity conditions were investigated. The results showed that the layered L-RAC100 slabs
performed as well as, or even better than, the NAC slabs due to the di erential shrinkage between
the layers. In terms of environmental performance, evaluated using a “cradle-to-gate” Life Cycle
Assessment approach, the L-RAC100 slabs also performed as well as, or slightly better than, the NAC
slabs. Therefore, layered NAC and RAC slabs can be a potentially advantageous solution from both
structural and environmental perspectives.

abstract = "Recycled aggregate concrete (RAC), i.e., concrete produced with recycled concrete aggregate
(RCA) has been heavily investigated recently, and the structural design of RAC is entering into
design codes. Nonetheless, the service load deflection behavior of RAC remains a challenge due to
its larger shrinkage and creep, and lower modulus of elasticity. A novel solution to this challenge
is the use of layered concrete, i.e., casting of horizontal layers of di erent concretes. To investigate
the potential benefits and limits of layered concrete, this study contains a numerical parametric
assessment of the time-dependent sustained service load deflections and environmental impacts of
homogeneous and layered NAC and RAC one-way slabs. Four types of reinforced concrete slabs were
considered: homogeneous slabs with 0%, 50% and 100% of coarse RCA (NAC, RAC50 and RAC100,
respectively) and layered L-RAC100 slabs with the bottom and top halves consisting of RAC100 and
NAC, respectively. In the deflection study, di erent statical systems, concrete strength classes and
relative humidity conditions were investigated. The results showed that the layered L-RAC100 slabs
performed as well as, or even better than, the NAC slabs due to the di erential shrinkage between

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  - Recycled aggregate concrete (RAC) has emerged as a viable solution for
solving some of the environmental problems of concrete production.
However, design guidelines for deflection control of reinforced RAC
members have not yet been proposed. This study presents a
comprehensive analysis of the applicability of the fib Model Code 2010
(MC2010) deflection control model to reinforced RAC beams. Three
databases of long-term studies on natural aggregate concrete (NAC) and
RAC beams were compiled and meta-analyses of deflection predictions
by MC2010 were performed. First, the MC2010 deflection control model
was tested against a large database of long-term tests on NAC beams.
Second, a database of RAC and companion NAC beams was compiled
and initial and long-term deflections were calculated using the MC2010
model. It was shown that deflections of RAC beams are significantly
underestimated relative to NAC beams. Previously proposed
modifications for MC2010 equations for shrinkage strain and creep
coefficient were used, and new modifications for the modulus of elasticity
and empirical coefficient β were proposed. The improved MC2010
deflection control model on RAC beams was shown to have equal
performance to that on companion NAC beams. The proposals presented
in this paper can help engineers to more reliably perform deflection
control of reinforced RAC members.

AB  - Recycled aggregate concrete (RAC) is a promising solution to addressing the sustainability issues raised by concrete production. However, its long-term properties are not fully characterised, especially creep behaviour, which is significant for the design of RAC structures. This study presents the results of a meta-analysis of previously published research on the creep behaviour of recycled aggregate concrete (RAC). The main goal of the study is to formulate an analytic expression for the creep coefficient of RAC as an extension of the fib Model Code 2010 creep prediction model. A database of experimental results on the creep of RAC and companion natural aggregate concrete (NAC), produced with the same effective water-cement ratio, was compiled from available literature and using strict selection criteria. The database is comprised of results from 10 studies, 46 creep curves (14 NAC and 32 RAC) and 233 data points. Compared with companion NAC, RAC displays a larger creep coefficient; the difference between RAC and NAC increases with increasing recycled concrete aggregate (RCA) content and decreases with increasing RAC compressive strength. When predicting the creep coefficient of RAC using the fib Model Code 2010's creep prediction model, relative to the model's performance on companion NAC, the creep coefficient of RAC is underestimated. A correction coefficient for the creep coefficient of RAC, xi(cc.RAC), is proposed for use with the fib Model Code 2010 model, dependent on RAC compressive strength and RCA replacement ratio.

AB  - Six simply supported reinforced concrete beams were tested under sustained loads for 450 days. The beams were made from natural aggregate concrete (NAC), recycled aggregate concrete (RAC) and high-volume fly ash concrete (HVFAC); two beams were made from each concrete and loaded after 7 and 28 days. On the beams, deflections, cracking and strains were measured while concrete specimens were used to determine physical-mechanical properties of concretes and measure shrinkage and creep. Results showed similar increases in deflections relative to initial deflections for all six beams. The results are also compared with code predictions and with existing results in literature.

This study intends to present results on the long-term properties of concrete produced with 100% coarse recycled concrete aggregate and concrete produced with 50% of class F fly ash in total cementitious materials and compare them with a companion natural aggregate concrete. The three concrete mixes were tested at the material level where shrinkage and creep were tested for 700 days on concrete prisms, and at the structural level where deflections, strains, and cracks of simply supported reinforc",

AB  - Reliably calculating the deflections is one of the more difficult aspects of the design of reinforced concrete members. All calculation models require a large number of experimental results for their calibration. Such results are lacking for beams made of green concretes with recycled and waste materials. This paper presents the results of applying analytical and numerical calculation models for predicting deflections of reinforced natural aggregate concrete, recycled aggregate concrete and high-volume fly ash concrete beams. Experimental results on six simply supported beams were compared with predictions obtained using the fib Model Code 2010 analytical model and a numerical model formulated using DIANA. Results confirm the applicability of these models in predicting deflections of green concrete beams.

AB  - Six simply supported reinforced concrete beams were tested under sustained loads for 450 days. The beams were made from natural aggregate concrete (NAC), recycled aggregate concrete (RAC) and high volume fly ash concrete (HVFAC); two beams were made from each concrete and loaded after 7 and 28 days. On the beams, deflections, cracking and strains were measured while concrete specimens were used to determine physical-mechanical properties of concretes and measure shrinkage and creep. Results showed similar increases in deflections relative to initial deflections for all six beams. The results are also compared with code predictions and with existing results in literature.
