AB  - Raw clay samples from Serbia, mainly of kaolinitic, illitic and mixed nature, were
tested for their possible application in the production of ceramics. Using various triaxial
diagrams, the samples were sorted according to their chemical and bulk mineralogical
makeup, and also particle size distribution to determine whether they could be
employed in the production of ceramics and refractories. The areas in the ternary graphs
determined in earlier studies concerning the expected color after firing and the
applicability of the raw clays are checked and extended. The samples' water absorption
and flexural strength were assessed using EN standard procedures after they had been
hydraulically semi-dry pressed and fired at several peak temperatures between 1100
and 1300 °C. A novel triaxial diagram considering the position of the samples based on
firing temperature, water absorption and modulus of rupture is proposed, and the areas
of different kinds of ceramic tiles are defined. It is discovered that the different raw
clays can be utilized to create refractory, as well as wall and floor tiles. This study
supports the rational use of natural sources of raw materials.

AB  - Waste tires have long been a challenge for waste disposal. In an effort to mitigate the impact of solid waste on the environment and recycle it as much as possible, research has been conducted into the possibility of using this waste in concrete mixes. However, the use of these waste materials in concrete is still not popular due to the lack of knowledge of the properties that can be obtained with this material. Hence, the aim is to use waste material in the production of concrete, and that concrete mixes with this material have satisfactory performance. The paper presents the results of research on concrete in which volume replacement of fine aggregate with crumb rubber was performed in the amount of 5%, and this concrete was compared with the control concrete mix and aerated concrete. All concrete are made with a water-cement factor of 0.45. The performance of fresh concrete was monitored for 10, 30 and 60 min. In the case of concrete with the addition of crumb rubber, after 60 min, higher values of air content were obtained, and lower values of volume mass of fresh concrete compared to the initial measurements. The obtained test results of hardened concrete indicate that concrete with crumb rubber has a lower compressive strength compared to the control concrete mix, while compared to aerated concrete, they obtain approximate compressive strength values.

AB  - Following the emergence and establishment of performance-based design as a widely recognized
and applied practice, numerous significant advances in computational techniques have been
made. Arguably, nonlinear methods of analysis – static or dynamic – provide the most detailed
and accurate insight into behavior of the structure which is designed or assessed. While the
current codes of practice permit their use, provisions are vague in some aspects, leaving many
decisions and assumptions up to the engineer. This paper aims to expand the relatively limited
experience with implementation of different distributed plasticity modeling approaches through
a case study based on experimental data. Some particulars of the behavior of structural elements
made of strain-softening materials, and of their corresponding numerical models, are briefly
introduced. Case study is conducted to provide an overview on the procedures for inelastic
analysis of reinforced concrete frames through a side-by-side comparison of four alternative
approaches for modeling of RC beams and columns with one-dimensional distributed plasticity
finite elements with fiber-discretized cross sections. The analyzed structure consists of a
reinforced concrete column with a fixed base, which is, under varying axial loads, subjected to
monotonic and cyclic lateral displacements applied at its top. Models comprised of force-based
elements with different arrangements of integration points, as well as of displacement-based
elements, are compared. Advantages, limitations and special considerations which need to be
taken into account for each of the approaches are demonstrated through the example. Influence
of concrete confinement is studied by analyzing another column with a different arrangement of
transverse reinforcement. Global structural response is evaluated by comparison of pushover and
cyclic curves for different models. Influence of modeling approach on objectivity of the local
response and the corrections which need to be made for certain approaches are showcased by
moment-rotation curves of the yielded section at the column base. Considerations and findings
presented in the paper, along with other published case studies, can be used for reference when
preparing a computational model for inelastic analysis of a reinforced concrete structure.

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  - 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  - 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.

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.

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

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%.

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 timedependent
relation.

AB  - The problems of steady-state and transient heat conduction for a given geometry can be
solved analytically and numerically. While the use of analytical solutions is limited,
numerical methods can be used to solve heat transfer problems in complex geometries
with more intricate boundary conditions, using computer simulations. Complex
geometries are discretized to form an efficient numerical mesh for solving the given
problem. This paper focuses on the calculation of one-dimensional, transient heat
transfer for a wall with a thickness of 4 cm. The wall temperatures are calculated for
each mesh node at a given moment in time. Two types of analyses were performed,
using FSM analysis (Finite Strip Method) and FEM analysis (Finite Element Method).
The former was conducted using Microsoft Excel, while the latter was calculatedusing
ANSYS software. A parametric study was performed in order to analyse the influence
of spatial and temporal step size on the accuracy of the solution. Finally, the optimal
solution was determined to obtain temperature results with the lowest relative error
within the wall nodes, while maintaining the efficiency of the computational model.

AB  - The technical features of the issues caused by the brick industry's usage of petroleum coke as a fuel were identified in this study. The effects were evaluated in terms of the concentration of hazardous materials in petroleum coke, the CO2, SO2 and NOx emissions in the flue gases, the corrosion of refractory materials in the furnace, the corrosion of pipelines and metal structures in the dryer and furnace, the deposition of sulfate scum on dry products, and the fixation of white scum on finished products. To assess the microstructure and composition of the regions of the samples exposed to flue gases and that inside the material, refractory brick samples from the furnace walls were examined under a microscope. The compressive stress of the part of the sample affected by the flue gas from the kiln is lowered by 37.3 %, which is caused by the agglomeration of sulfate salts and the presence of a high quantity of vanadium. It was determined that, regardless of potential energy savings, the sulfur concentration in petroleum coke must be below 5% if utilized as an energy source in the brick sector since there are suitable conditions for accelerated corrosion processes.

AB  - The European Green Deal, which emphasizes zero-waste economies, and waste recycling
in construction and building materials, has arisen due to significant worldwide needs for solid waste recovery and usage. This ambitious study focuses on recycling mixed construction and demolition (C&D) waste into burnt bricks and investigating the influence of firing temperature. While pursuing its objectives, this is dependent on raw material characterization and burnt-brick product quality assessment. The recycling of mixed C&D waste is explored by mixing the waste into two soil types (alluvial and laterite) in ratios ranging from 5% to 45% at three firing temperatures (700 °C, 850 °C and 900 °C). The utilization of mixed C&D waste in amounts of 10% at 700 °C and 25% at 850 °C and 900 °C fulfilled the Indian standard. Although a fire at 700 °C results in less optimal waste utilization, it is beneficial and recommended for reducing the carbon footprint and energy use. Additional mineralogical and microstructural analyzes are performed on the optimal fired samples.
The study’s findings are promising for sustainable resource usage, reducing carbon footprint, and
reducing waste disposal volume. This research is a big step toward the Sustainable Development
Goals of the United Nations and a circular economy.

The concept of corrosion in welded joints is very pronounced in real conditions. Welded joints are
inseparable joints that form an integral part of steel welded constructions. The internal energy
increases during the fusion welding especially in the heat affected places around the welded joint,
which become initiating spot of corrosion degradation. That is why it is of vital importance to focus
on ways to increase the resistance of welded structures to the impact of corrosion.

AB  - 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.

AB  - In the paper, based on the results of experimental research on the behavior of samples in the form of
round smooth test specimens (STS) made of high strength low alloy steel (HSLA), Nionikral 70 (NN
70), under conditions of low cycle fatigue (LCF), a computational stress analysis was performed
using numerical methods.
Experimental investigations of the behavior of the samples were performed with controlled and fully
reversible deformation ( /2 = const, R = min/ max = 1), according to the ISO 12106:2003 (E)
standard.
For computational analyses, the method of least squares (in the Excel program) and the finite
element method (FEM) (in the SolidWorks program) were used. The behavior of HSLA steel during
low cycle fatigue (LCF) simulation was analyzed in the Cosmos module of the SolidWorks program.
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. Specific load cycles involving the entire round smooth test specimen
ligament for a specific load in a wide range of LCF loads were analyzed.
The analyzes showed the justification of the effort to solve the life assessment of steel subjected to
low cycle fatigue (LCF) numerically. The results of experimental tests and simulation tests also gave
us important data on understanding the LCF behavior of HSLA steel NN 70.

AB  - In the paper, the analysis of the bearing capacity of the pile and the redistribution of the
load on the pile toe and shaft was carried out. The tests were carried out by a static load test (SLT)
incrementally increasing the compressive force on the test pile, and the tension force on the anchor
piles. The test system consisted of one test pile and two anchor piles with a reaction beam. Two
tests were conducted according to the same test program, where the test piles were of the same
length, while the length of the anchor piles in the second test was increased. In the first test, the
anchor pile failed, while in the second test, the test pile failed. Based on the achieved limit values of
settlement of the test and anchor pile, the bearing capacity of the test pile at the toe and shaft was
determined. Subsequently, a CPT test was carried out and the bearing capacity was calculated
according to the LPC-CPT method.
