AB  - The performance of thermo-insulation rendering mortars with alternations in ratios of powdered cordierite and talc was examined. The goal was to confirm that recycled kilnware cordierite can be reapplied in the mortar design without significant deterioration in performance in comparison with OPC mortar. Differential thermal analysis was employed for examining thermally induced reactions. The cavitation erosion, in testing sequences ranging from 30 to 120 minutes, was used to assess the compactness of the mortar structure. The physico-mechanical properties of experimental mortars were investigated. The morphologies of the mortar tablets upon cavitation were studied using a scanning electron microscope. It was established that cordierite and talc filler in amounts up to 20% enhance microstructural packing and mechanical strengths due to improved cementation and therefore contribute to cavitation erosion resistance. Higher amounts of talc cause structural degradation and mass loss during cavitation tests. Reducing manufacturing costs, energy consumption, and greenhouse gas emissions are the main objectives of the production of this waste-based construction composite, as the reuse of waste materials can help achieve a number of Sustainable Development Goals.

AB  - Smelting used to be less efficient; therefore, wastes obtained from historical processing at smelter plants usually contain certain quantities of valuable metals. Upon the extraction of useful metal elements, metallurgical slag can be repurposed as an alternative mineral raw material in the building sector. A case study was conducted, which included an investigation of the physico-chemical, mineralogical, and microstructural properties of Pb–Zn slag found at the historic landfill near the Topilnica Veles smelter in North Macedonia. The slag was sampled using drill holes. The mineralogical and microstructural analysis revealed that Pb–Zn slag is a very complex and inhomogeneous alternative raw material with utilizable levels of metals, specifically Pb (2.3 wt.%), Zn (7.1 wt.%), and Ag (27.5 ppm). Crystalline mineral phases of wurtzite, sphalerite, galena, cerussite, akermanite, wüstite, monticellite, franklinite, and zincite were identified in the analyzed samples. The slag’s matrix consisted of alumino-silicates, amorphous silicates, and mixtures of spinel and silicates. Due to the economic potential of Pb, Zn, and Ag extraction, the first stage of reutilization will be to transform metal concentrates into their collective concentrate, from which the maximum amount of these crucial components can be extracted. This procedure will include combination of gravity concentration and separation techniques. The next step is to assess the Pb–Zn slag’s potential applications in civil engineering, based on its mineralogical and physico-mechanical properties. Alumino-silicates present in Pb–Zn slag, which contain high concentrations of SiO2, Al2O3, CaO, and Fe2O3, are suitable for use in cementitious building composites. The goal of this research is to suggest a solution by which to close the circle of slag’s reutilization in terms of zero waste principles. It is therefore critical to thoroughly investigate the material, the established methods and preparation processes, and the ways of concentrating useful components into commercial products.

AB  - The traditional ceramics industry uses large amounts of primary mineral raw materials. Improvements in the production of building materials based on non-metallic minerals can contribute to sustainable development in many ways, such as saving natural resources, using waste materials, reducing energy consumption, decreasing emissions hazardous to the health and the environment, particularly carbon dioxide, and reclamation of mines after exploitation of raw materials, etc. This paper describes the state of application of mineral raw materials and waste in the traditional ceramics industry with a perspective on future challenges. Intensified research is needed to complement the laboratory data and re-scale to the industrial-sized products while improving communication between both sectors.

AB  - This study illustrates the utilization of roof tile waste as a resource in the manufacturing of fired bricks. Although commonly referred to as demolition waste, it is technically classifed as construction and demolition waste
(C&D). This demolition waste was used as a partial replacement of two soils (alluvial and laterite soil) at three firing temperatures that were considered economical (700, 850, and 900 ◦C). The waste considered was obtained from roof tiles previously fired at a low temperature below 800 ◦C, thus containing residual carbonates and clay
minerals. The increased waste input resulted in higher firing shrinkage, bulk density, and water absorption while
decreasing loss on ignition. An increase in firing temperature led to higher firing shrinkage, loss on ignition, and
bulk density, but lower water absorption. The bricks met both Indian and ASTM standards for 2nd and 3rd class
by adding 20–35 wt% of roof tile waste and firing at 850–900 ◦C in laboratory and industrial settings. The
minimum acceptable quality for the produced bricks was achieved with an addition of 35 wt% waste, resulting in
a water absorption of approximately 19% and a compressive strength ranging from 6 to 9 MPa. The study suggests that incorporating waste from demolished roof tiles into the production of burned bricks can be advantageous.
It can partially replace the need for soils, reduce natural resource usage, lower energy consumption
during production, and decrease the carbon footprint.

AB  - The primary objective of this study was to look into the role of titanium dioxide in the production of corundum-based mortars, with a focus on finding the optimal mortar composition for achieving improved mechanical and dielectric performances. Changes in the mix design (different binders, different additive dosages), as well as their effects on the hydration pathway, chemical bonds, phase modifications, and microstructure, were examined. These findings were then correlated to the designed mortars' mechanical strengths and dielectric properties. Experimental mortars were produced with binders made from ordinary Portland cement, high alumina cement, and their mixtures, and corundum as aggregate. Titanium dioxide was employed as an additive (3 and 5 wt%). Nine different mortars were submitted for comprehensive mineralogical and microstructural characterization upon curing and solidification. The compressive and flexural strengths were monitored throughout the 28-day period. The dielectric constant (εr), dielectric loss tangent (tan δ), and electrical resistivity (ρ) were measured over a frequency range of 100 Hz to 1 MHz. XRD analysis highlighted the appearance of mayenite as a dielectric-prone phase in the samples doped with titanium dioxide. Differential thermal analysis and FTIR spectroscopy identified a higher amount of extra-low crystalline phase in OPC and HAC mortars with TiO2 addition, which accelerated hydration mechanisms, created a surplus of hydration products and made a more compact cement matrix. TiO2 added in 3 wt% amount led to higher mechanical strengths in OPC-based mortars, while it improved the dielectric properties of HAC mortars.

AB  - Most serious weldment failures have catastrophic consequences in terms of damage to other equipment,
loss of production, and risks to worker health and safety. For the above reasons, there is a tendency to find the
line between safety and disaster, and this requires a guarantee of the integrity of the welded structure even if a
crack is present.
The structural and mechauical heterogeneity of a welded joint affects its resistance to cracking in both the
elastic and plastic regions. Therefore, it is important to define the test method and the position of the fatigue
crack. The behavior of an elasto-plastic material, during stable crack growth can be described by the J-1\a
diagram. As the crack propagates, a point on the curve is defined, which represents the critical value of the Jintegral.
The aim of this experiment is to determine ne value and the procedure is reflected in the
determination of the R curve, i.e. the J-1\a curve, which consists of the value of the J integral for uniform
crack increments 1\a. In this paper, two SEN(B) specimens with the fatigue crack in the parent material (PM)
and weld metal (WM) were tested according to standard ASTM El820 at room temperature (RT) as well as
three specimens with the fatigue crack in the weld metal (WM) at RT, -20C, -30C.

AB  - During the last 10 years it was shown that Deff – MR curve pattern is unique and very useful. This ability was firstly embedded in the procedure for setting up the fast drying regimes several years ago. This incredible pattern was used again in this invited paper. Actually, if the test samples formed from the same clay do not crack during drying in at least two isothermal experiments in which drying air temperature was different, while drying air humidity and velocity were constant, the unique line can be constructed. This line is linking corresponding Deff – MR curves through the same characteristic point. For simplicity reasons it was chosen to construct and use only the unique line pulled through characteristic E points. Its slope was proposed as the objective criteria for evaluation of the clays suitability for the rapid drying application.

abstract = "During the last 10 years it was shown that Deff – MR curve pattern is unique and very useful. This ability was firstly embedded in the procedure for setting up the fast drying regimes several years ago. This incredible pattern was used again in this invited paper. Actually, if the test samples formed from the same clay do not crack during drying in at least two isothermal experiments in which drying air temperature was different, while drying air humidity and velocity were constant, the unique line can be constructed. This line is linking corresponding Deff – MR curves through the same characteristic point. For simplicity reasons it was chosen to construct and use only the unique line pulled through characteristic E points. Its slope was proposed as the objective criteria for evaluation of the clays suitability for the rapid drying application. It was found that clays, for which the unique line slope is larger, had better dimensional and mechanical properties and were more suitable for the construction of the fast drying regimes.",

biodegradable and non-toxic, which are the main advantages of using such composites. Based on the
research results described in this paper, it was concluded that by adding natural fibers to the composite,
certain characteristics can be significantly improved. This paper describes some of composite material
characteristics based on PLA, modification of PLA, advantages and disadvantages of using PLA in

AB  - Designing, constructing and putting into operation a hydroelectric power plant includes complex
tasks. Stresses of turbine and hydromechanical equipment of hydro power plants arise during the
production of parts and assembly of equipment (residual stresses), in the process of performing
functional requirements in exploitation and in the disturbed process of exploitation.
After several decades of constant exploitation of the horizontal bulb turbine, which is an integral
part of the hydroelectric power unit, empirically, the formation of a crack occurs in the turbine
shaft due to the influence of corrosion, erosion and cavitation.
Through experimental tests and calculations it has been determined that values of bending stresses
of the turbine, which occur due to the action of fatigue and corrosion, as well as stress
concentration, are bigger than 25 MPa for flanges exposed to water, and in other case bigger than
40 MPa for flanges exposed to `corrosive water` and can cause the occurrence of surface cracks
on the transition radius between the cylindrical part of the shaft and the flange. It has been
determined that stress values in the zone under the influence of bending stresses were bigger than
allowable values, which led to the occurrence of many cracks due to fatigue corrosion. One of
those cracks caused the failure of the shaft and of the whole turbine.

improved microstructure packing, strength, and durability thanks to the use of fly ash, a
highly effective mineral additive. Performances of SCC with fly ash and conventional
SCC with limestone filler were compared. Additional experimental self-compacting
concretes were made and adjusted with various types of fine aggregates, fillers, and
unique additives to increase freeze-thaw resistance. The relationship between the
proportion of barite sand and additives and the properties of SCC was investigated and
discussed. Tests of freeze-thaw resistance with and without de-icing salts are the main

AB  - Global warming and the emission of CO2 into the atmosphere is becoming a bigger
problem in the world every year. The desire for a global increase in production and the
ever-increasing development of industry are the cause of the increased amount of waste
in landfills and environmental pollution. Concrete is the most used construction material
in the world, and the production of its main ingredient, cement, is responsible for about
7% of CO2 emissions in the world. Application of waste materials and by-products that
end up as waste during some industrial process in production can find further
application in concrete. Such materials can be used as mineral additives or as aggregate
fillers, for partial or complete replacement of natural stone aggregate and/or cement. In
this work, volume replacement of the fine fraction with 2.5 and 7.5 % crushed rubber
was performed. Based on the test results of fresh concrete, in concrete with rubber
addition, the slump consistency and bulk density decrease, and the air content
increases. A drop in compressive strength of concrete was observed with an increase in
the rubber content of 7.5%.

AB  - In the paper, based on the results of the experimental research of high-strength low-alloy steel
(HSLA), Nionicral 70 (NN-70), under conditions of low-cycle fatigue (LCF), a numerical analysis of
stress and determination of the life of steel samples was performed. Experimental testing of the
behavior of the samples were performed with controlled and fully reversible strain (/2 = const,
R = min/max = -1), according to the standard ISO 12106:2003 (E). For computational analyses, the
following were used: the method of least squares and the method of finite elements (FEM). On the
basis of the analysis of the results of the stress-deformation state and the determination of the life
span through the isolines of the life span and comparison with the results of experimental tests, a
graphic representation is given. The analysis justified the effort to numerically solve the estimation
of the lifespan of steel under low cycle fatigue (LCF).

abstract = "In the paper, based on the results of the experimental research of high-strength low-alloy steel
(HSLA), Nionicral 70 (NN-70), under conditions of low-cycle fatigue (LCF), a numerical analysis of
stress and determination of the life of steel samples was performed. Experimental testing of the
behavior of the samples were performed with controlled and fully reversible strain (/2 = const,
R = min/max = -1), according to the standard ISO 12106:2003 (E). For computational analyses, the
following were used: the method of least squares and the method of finite elements (FEM). On the
basis of the analysis of the results of the stress-deformation state and the determination of the life
span through the isolines of the life span and comparison with the results of experimental tests, a
graphic representation is given. The analysis justified the effort to numerically solve the estimation
of the lifespan of steel under low cycle fatigue (LCF).",

AB  - Preparation for non-destructive testing (NDT), preparation of test reports, as well as control
calculation of a pressure vessel (PV) using the finite element method (FEM), with or without
identified irregularities, requires the use of commercial programs for parametric modeling,
which allow the rapid creation of three-dimensional (3D) model of the test object. 3D modeling
programs enable the determination of one or more rappers in order to orient the test object,
accurately define the established irregularity or error after NDT, as well as the most critical
part of the PV construction after FEM calculation with the possibility of optimization.
Programs for 3D modeling also enable modeling of determined irregularities after performed
tests that occurred during the construction, calculation, production or exploitation of the PV
construction itself. Irregularities are reflected in the form of improperly performed welded
joints, cracks, corrosion, erosion or cavitation of materials, and are used for the preparation of
test reports and control calculations of the PV structure with and/or without established
irregularities and errors, with the aim of making the correct decision on the continuation of
exploitation construction of PV or about its degree of rehabilitation

AB  - In this paper, the drying modeling of roofing tiles was done using a "lumped" approach. In other words, several forces that are influencing internal moisture transport are combined to create effective moisture diffusivity. For this reason, the effective diffusivity coefficient was added to Cranck's diffusion equation. In their earlier works, the authors published the solution to the diffusion equation, which assumes that effective diffusivity is constant. It was demonstrated that, particularly if shrinkage is not taken into account during the computation stage, the simulated drying curves differ from the experimental results. The next step was to ascertain the time-dependent effective diffusivity and to more precisely anticipate the drying kinetic. The general functional relationship between effective moisture diffusivity and Fourier number was first determined to fulfill this assignment. Experimental proof of the proposed model was provided. Less than 3% of the outcomes from the simulation and the experiment deviated from each other. This was a resounding affirmation that effective diffusivity is not constant during drying and that all internal transport mechanisms are observable in their time-dependent relation.

For 19 composite samples from the recently opened reservoir, thorough instrumental and ceramic-technological data are presented. The potential for using Serbian raw refractory clays from the recently discovered deposit is investigated. The composites had a variety of qualities and varied in composition, but they were majorly composed of kaolinite and illite and had a significant share of fluxes. The samples had high quantities of clay minerals and organic matter, which is seen as the most intense mass loss in the 400–600 °C range. Low-duty and high-duty refractories could be distinguished by their refractoriness over 1581 °C. This parameter was mostly influenced by the content of alumina and kaolinite within the materials. Hydraulically-pressed ceramic tiles, following firing stage showed water absorption was between 9.02–1.42 % and and modulus of rupture of 16.5 – 53.6 MPa. Color is determined by spectrophotometer and correlated to the composition of the initial clay and fired products. For the lining of ceramic and glass furnaces, the majority of these clays can be employed as natural refractory materials. Some of the samples' organic content has a detrimental effect on the fast-firing procedure, since the occurrence of the entrapped air (bloating).

AB  - In this paper, the drying modeling of roofing tiles was done using a "lumped" approach. In
other words, several forces that are influencing internal moisture transport are combined to
create effective moisture diffusivity. For this reason, the effective diffusivity coefficient was
added to Cranck's diffusion equation. In their earlier works, the authors published the solution
to the diffusion equation, which assumes that effective diffusivity is constant. It was
demonstrated that, particularly if shrinkage is not taken into account during the computation
stage, the simulated drying curves differ from the experimental results. The next step was to
ascertain the time-dependent effective diffusivity and to more precisely anticipate the drying
kinetic. The general functional relationship between effective moisture diffusivity and Fourier
number was first determined to fulfill this assignment. Experimental proof of the proposed
model was provided. Less than 3% of the outcomes from the simulation and the experiment
deviated from each other. This was a resounding affirmation that effective diffusivity is not
constant during drying and that all internal transport mechanisms are observable in their timedependent
relation.

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.
