AB  - The applicability of solid bricks waste in geopolymerization technique was considered. Waste samples were characterized in terms of mineralogical composition by XRD prior to mechanical testing. XRD analysis showed that both brick samples contained anorthite, wollastonite, and mullite as the main components. The compressive strength investigation was carried out by screening method with three geopolymer mixtures. Geopolymer mixtures were prepared with alkaline activators; the mixtures were poured into molds and air-dried for 28 days. The compressive strength of samples was measured according to the standard SRPS EN 12390-3:2010 for cubic samples. The compressive strength values ranged from 9.8 MPa for the newer solid brick, 10.2 MPa for the older solid brick, and 10.5 MPa for the solid brick mix waste geopolymer sample. The most likely underlying reason for the higher compressive strength results of the older solid brick and the mixed sample is their mineral composition, i.e. higher proportion of aluminosilicate. However, all samples showed satisfactory compressive strengths, and it represents an excellent basis for further research.

AB  - The construction sector is responsible for approximately 39% of energy use and process-related carbon dioxide emissions. Mixing waste materials into concrete, as a substitute for cement 
and/or aggregate, increases energy efficiency and sustainability in general. Additionally, pressure 
on the environment is decreasing by reducing the amount of exploitation of natural raw materials. 
On the other hand, the rapid progress of the electronic industry has led to the generation of a large 
amount of electrical waste before the end of its useful life. Disposal of old monitors and TV screens, i.e. their cathode-ray tubes (CRT), represents a major problem for the environment because CRT waste is classified as hazardous due to its high lead content. This paper deals with an overview of investigations on CRT waste utilization in cement materials in order to increase sustainability and encourage a circular economy in the construction sector.

AB  - In this research, tests of mortar and porous concrete made with solidified waste water treatment sludge (SWWTS) used in two forms as a partial replacement of cement were carried out. SWWTS mainly consisted out of CaCO3 and Ca(OH)2, having no pozzolanic properties. For this reason, it was used both, as produced, and modified by adding Al2O3 and Mg3Si4O10(OH)2 in certain percentages. One mortar type and two types of porous concrete were tested. For each of the three products two mixtures were prepared: the reference mixture and the mixture made with 30% replacement of cement, while the other components remained the same. Based on the given comparative analysis, conclusions were drawn regarding the structure of porous concrete slabs, which refer to individual analyzed properties, but also to the possibility of applying energy-efficient materials. The obtained results point to the conclusion that the use of SWWTS reduces the values of almost all tested properties of porous concrete (flexural and compressive strength, pull-off strength, abrasion resistance), but also that the modification of SWWTS led to a smaller difference in the results of the samples made with 30% of cement replacement and the reference samples. Although, the use of SWWTS led to the reduction of mechancal properties of concretes, the most important benefit is development of possible way for reuse of this waste material and avoid its disposal in the landfills.

AB  - The increased number of water treatment plants induces intensified production of water treatment sludge (WTS) that needs to be stabilized and reused. One of the possible stabilization processes is solidification, which involves the reaction of wastes with additives based on calcium-oxide and calcium-hydroxide. The final product of these reactions (solidified water treatment sludge - SWTS) is an inert material that can be used as a filler, but not as a supplementary cementitious mate-rial (SCM) - due to its insufficient pozzolanic activity. The paper presents the possibilities of application of modified SWTS (MSWTS) as a SCM when mixed with aluminium-oxide and magnesium-silicate. In order to achieve this, mortar mixtures were prepared with partial replacement of cement by using MSWTS in amounts of 10%, 20% and 30%. Flexural and compressive strength tests, togeth-er with ultrasonic pulse velocity, as well as with capillary water absorption and freeze-thaw resistance were performed. The obtained results point to the conclu-sion that the increase in the percentage content of MSWTS consequently led to a decrease in the mechanical properties of the tested samples, which limits the pos-sible cement percentage replacement in plasters.  The decrease in flexural strength ranged between 3% and 8% and in compressive strength between 8% and 19%.

AB  - Although, the salt crystallization is one of the most common causes of the deterioration of lime-based mortars, testing of their resistance to the soluble salt action has not yet been standardized. The problems following the development of the globally accepted testing method are, among others: defining the type of mortar samples, ways of samples’ contamination, the type and the concentration of the salt solutions used, environmental conditions during testing, determination of the damage development and the durability assessment. Another task of the testing method is to explain and connect the processes developing in the materials when they are applied in laboratory and real conditions. In this paper, soluble salt resistance testing of lime mortars on the composite samples is presented. The main focus of the paper is on the determination of the salt distribution in this type of samples after the five wetting and drying cycles. Samples consisted of two lime rendering layers (inner – 1/3 and outer -1/1), both prepared according to the experiences found in the literature for these types of lime mortars when applied on historical structures, placed on the natural stone bases. They were cured in laboratory conditions for 90 days, before drying and exposing to soluble salts action. Two types of 10% salt solutions were used for the test: sodium-chloride and sodium-sulfate. Salt contamination was performed by capillary action only in the first cycle, while in the other cycles samples were wetted by deionized water. After the finalization of the cycles, the detached pieces of mortar and efflorescence were removed from the samples. One of the samples from both groups were then cut in two halves, from which one was used for X-Ray Fluorescence (XRF) and another for Scanning Electron Microscopy with Energy Dispersive X-Ray Analysis (SEM – EDX) characterization. For the XRF analysis samples were divided into four layers, and then crushed and sieved through 0.5 mm sieve before testing. For the SEM-EDX analysis the polished thick cross sections were prepared. The paper presents the results of these two analyses, and discusses the advantages and disadvantages of their application for this purpose. Mineralogical analysis of the samples was performed using XRD analysis. It was shown that XRF analysis provides more precise quantification of the elements within one sample, while SEM-EDX analysis gives possibilities for testing of layers with smaller depth within one cross – section.

abstract = "Although, the salt crystallization is one of the most common causes of the deterioration of lime-based mortars, testing of their resistance to the soluble salt action has not yet been standardized. The problems following the development of the globally accepted testing method are, among others: defining the type of mortar samples, ways of samples’ contamination, the type and the concentration of the salt solutions used, environmental conditions during testing, determination of the damage development and the durability assessment. Another task of the testing method is to explain and connect the processes developing in the materials when they are applied in laboratory and real conditions. In this paper, soluble salt resistance testing of lime mortars on the composite samples is presented. The main focus of the paper is on the determination of the salt distribution in this type of samples after the five wetting and drying cycles.

AB  - This paper deals primarily with research and testing of ultra-high performance concrete (UHPC) made with or without the addition of steel fibers. Two stages of research are presented and discussed in detail: first - UHPC based mostly on local component materials and produced in the form of a premix with a commercial name ForteCrete150®, and second – modified UHPC, made with a partial cement substitution by limestone filler, as a more eco-friendly and sustainable solution. The obtained results indicate that there is a great potential for application of ultra-high performance concrete, especially in the form of premix that can be prepared on-site. The addition of limestone filler (and potentially other types of mineral additives) as SCM, could generally contribute to improvement of a negative agenda surrounding the cementitious composites.

AB  - Presented research was intentioned to clarify the effects of thermal treatment (ageing) of reinforcing steel products on their mechanical and deformation properties. In order to determine the effect of temperature, samples were exposed to room temperature (reference samples) and a temperature of 100 °C in duration of 30, 60 and 120 minutes, respectively. Tests were conducted on bars, coils and welded fabrics. After the thermal treatment, samples were exposed to tensile testing. The duration of the ageing treatment did not significantly affect measured properties of the tested products. Still, longer ageing process increased the yield stress of samples taken from coils by 7%, while the welded fabrics reached optimum values of yield stress and elongation after ageing of 60 minutes.

AB  - Waste and recycled materials have recently been used in the construction industry to comply with the principles of circular economy and sustainable development. The aim of this paper is to examine the potentials of solidified wastewater treatment sludge (SWWTS) as a supplementary cementitious material (SCM) in the production of lightweight pervious concrete pavers (LWPCP) suitable for pedestrian trails and rooftops (green) that comply with EU standards. Detailed characterization of SWWTS was performed, in order to understand its properties related to application as SCM, which led to the conclusion that it may be applied only as a filler, having 89.5% of Ca(OH)2. After thorough characterization, LWPCP samples were prepared and testing of physical and mechanical properties was conducted. The research showed that partial replacement of cement with SWWTS led to the decrease of all mechanical properties, ranging between 3.91 and 5.81 MPa for compressive strength and 0.97 to 1.23 MPa for flexural strength. However, all of the investigated mixtures showed a value higher than 3.5 MPa, which was defined as the lowest compressive strength in the range of pervious concrete properties. The addition of SWWTS led to a slight decrease in bulk density of the mixtures and an increase in water absorption. This could be explained by the reduction in hydration products that would fill in the micropores of the matrix, since SWWTS showed no pozzolanic reactivity. Pore sizes that prevail in the tested binder matrices are in accordance with the results measured on ordinary pervious concrete (the largest fraction of pores had a diameter between 0.02 and 0.2 μm). Low thermal conductivity nominates produced pavers as potential rooftop elements.

AB  - It is common to use mechanical fasteners and electrochemical joining of elements by welding - all of which nowadays represent traditional fastening methods. However, in some situations it is justified to use alternative bonding methods such as adhesives. Adhesives are widely used fastening method in the aerospace and motorcycle industries, while in construction they are mostly used in facade structures, structural glazing and secondary structural elements. The application of certain adhesives depends on many factors, and some of the most important are: the material to be joined, the conditions in which the connection takes place, the thickness of the layer, the required setting time, etc. In this paper, a theoretical review was given, together with results of experimental tests performed on two types of joints made of silicone: double-lap shear (shear joints) and pull-off (tension joints). The applied structural adhesive was Sikasil SG-18. The samples which were used consisted of steel, aluminum and MCM (metal composite material).

AB  - The guarded hot plate (GHP) method is a widely used technique to measure
thermal conductivity of thermal insulation specimens in steady-state conditions.
In this paper, an advance of GHP has been developed in the Laboratory for
Thermal Technique and Fire Protection in Institute IMS. The innovative GHP
has been applied for measuring thermal conductivity using additional heat flux
meters. The design of this GHP is similar to the design of the plate for GHP apparatus, however, it has different design: smaller width of thermal barrier, which
is filled with insulation glue. Heaters inside hot and guard plates are built from
wire for thermocouples, which is a unique type of heater. Geometry of heater has
been optimized inside plates to achieve uniform temperature distribution along
the specimen surface. Temperature uniformity of GHP and energy balance were
experimentally determined. The verification and validation results of improved
GHP have been shown. The test method was validated comparing test results of
thermal conductivity with results of the round-robin test. Four national companies participated in the round-robin comparison on thermal conductivity measurement by GHP method. The measurement was performed on the same specimen
of thermal insulation material (expanded polystyrene) according to SRPS EN
12667 at temperatures ranging between 10-40 °C. The measured thermal conductivity of all participants in the round-robin test was input data for statistical
processing according to SRPS ISO 5725-2 and ISO 13528. To evaluate the performance of the participants, the “z” score has been used. Measurements were
conducted successively for all participants. Since 2020, the Accreditation Body of
Serbia also approved this test method.

AB  - The production of ultra-high performance concrete is one of the new ideas in modern construction, developed in the past few decades. A compressive strength higher than 150 MPa has been achieved using a relatively large amount of cement, approximately 800 kg/m3. As the cement industry is one of the largest producers of carbon dioxide, it is clear that the cement amount in concrete should be reduced to minimize greenhouse gases emission and slow down the global warming process. One possibility for that reduction is a replacement of cement with limestone filler.
This paper shows the results of experimental testing of five ultra-high-performance concrete mixtures. A referent mixture and four mixtures with a partial replacement of cement with limestone filler were made and tested. Two types of limestone fillers varying in particle size were used: one with a mean particle size of 2.5 μm and the other one with a mean particle size of 11 μm. Two groups of concrete mixtures were made with 20% and 30% of cement replaced by limestone. All other components: silica fume, quartz sand, water and superplasticizer were kept constant in all mixtures. Limestone filler is selected based on a particle size - so that its particles are the same size or smaller compared to cement. Basic fresh and hardened concrete properties were tested for all mixtures: consistency was determined using standard flow test and 28-day compressive strength was obtained by testing 10-cm cube samples.
Based on the obtained results, it could be concluded that the replacement of cement with limestone brought improvements in compressive strength and workability. The compressive strength of all mixtures was app. 120 MPa, while the mixtures with limestone were more flowable. The economic aspect was also considered. The analysis showed that up to 25% cost reduction can be achieved without compromising the compressive strength of this type of concrete by using limestone as a filler.

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  - Copper slag, produced as a by-product of the pyrometallurgical process of obtaining copper from copper ore in Bor, is disposed as waste in landfills. Despite the favorable physical and mechanical properties of concrete made with copper slag aggregate, such as higher compressive strength (40.8 MPa), higher tensile splitting strength (10.3 MPa), higher pull-off strength (3.1 MPa) and lower water permeability, its use in the construction industry has not been sufficiently investigated. The paper shows the possibility of using copper slag aggregate (CSA) in concrete as a potential replacement for natural river aggregate (RA). As part of the experimental tests, the environmental impact of using CSA as a substitute for RA in the production of mixed concrete was analyzed. The analysis included two concrete mixtures with partial replacement of coarse natural aggregate with copper slag aggregate in three different impact scenarios

AB  - Salt crystallization of lime-based rendering mortars is one of the most common reasons for their deterioration. Still, testing of the resistance to soluble salt action has not yet been standardized for this type of material. Lime-based renders are usually placed in several layers, each of them having a specific role and composition. Nevertheless, tests used in the literature are commonly performed on standardized prismatic or cylindrical mortar specimens. This paper presents a comparison between damage development on the composite samples, prepared on porous stone substrate with two types of rendering mortars, and standardized prismatic mortar specimens. Samples were prepared with pure putty lime mortars and lime-putty based mortars with the addition of natural zeolite. Two types of composite samples and four types of prismatic samples were used during the test. The testing was conducted at the age of 90 days using two types of salt solutions (NaCl and Na2SO4). Damage development was followed visually during five cycles of wetting and drying. Salt distribution using XRF analysis was measured at the end of the test on composite samples. It was shown that damage development greatly depends both on sample and mortar types.

The changes in zeolite content led to different pore size distributions of mortars and influenced their water transport behavior and open porosity.

AB  - Lime-based renders were usually placed in several layers, each of them having specific role and composition. In this paper, physical and mechanical properties of lime mortars for the final layer (coating) at the age of 90 and 180 days were presented. Durability aspect of the tested mortars was considered through testing of their behavior in the presence of the soluble salts. Four mortar mixtures were tested (one reference mortar and three mortars with partial replacement of lime with natural zeolite). For all mortars tested it can be seen that there was no improvement in strength between two tested ages. Mortar with 30% of lime replaced with zeolite reached higher value of compressive strength and almost the same value of capillary water coefficient as reference mortar. Vapor permeability grew with the increase of the natural zeolite content. Mortars showed good resistivity to the presence of sodium-chloride and developed cracks and loss of compressive strength when exposed to the solution of sodium-sulfate.
