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.

AB  - During the MoDeCo2000 scientific and research project on mortars used in the territory of the Roman Danube Limes in Serbia, the biggest challenge was the quest for the provenance of raw materials. The area where Viminacium, the largest city in the province of Moesia Superior developed, with millennial continuity of land use and settlement, was selected as research case study and is presented in this research. People throughout history have always used what they had at hand, and the building remains were not only reused but also recycled for new constructions. Thus, the building material of Roman Viminacium has survived in the landscape through the in situ preserved remains of Roman buildings, as well as in the structures from the later periods, up to today. To the best of our knowledge, the use of natural sediments baked during the self-combustion or combustion of underneath layers (coal in our case) for the purpose of construction was extremely rare in the Roman Empire. In this study, we follow the presence of this type of material precisely in Viminacium construction, naming it natural brick, while focusing on its potential use in lime mortars whose production was perfected in the Roman period and has never been surpassed afterward. Archaeological contexts in which this material was found have been studied, along with simultaneous work in the laboratory and in the field during the research and experimental use of the natural brick in lime mortars. We sought to determine whether this material could have been recognised by Romans in Viminacium as a potential valuable pozzolanic component of mortar, along with or instead of fired brick, being locally available and recyclable. The final confirmation of its pozzolanic features and later discussion open completely new directions for the future research of Viminacium lime 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  - 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  - Preparation for non-destructive testing (NDT), preparation of test reports, and control
calculation of a pressure vessel using the finite element method (FEM), with or without identified
irregularities, requires the use of commercial parametric modeling programs. 3D modeling
programs enable the determination of the most critical part of the pressure vessel construction
as well as the modeling of irregularities after the tests that occurred during the construction,
calculation, and exploitation of the pressure vessel 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 pressure vessels construction with and/or without identified irregularities and
defects, with the aim of making the correct decision on continued exploitation of the pressure
vessel construction or its degree of repair.
The possibility of an unlimited number of views, as well as the possibility of an unlimited number
of sections of the entire pressure vessel structure or its part, releases us from creating
complicated 2D sketches for the purpose of NDT or control calculation of the pressure vessel
FEM structure.
In connection with other computer programs or for the calculation of FEM (fracture mechanics,
fatigue), pressure vessel models made in 3D, enable the preparation of a quality test report with
the defined traceability and repeatability required by the SRPS ISO/IEC 17025 standard, as well
as the making of the correct decision on the exploitation and service life of the structure pressure
vessel.

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  - To evaluate the behavior of a homogeneous material in the presence of a crack-type defect, the
value of the critical stress-intensity factor, KIc, was determined as a measure of the fracture
toughness of the tested steel under the conditions of a plane stress state, at two test temperatures,
20 C and 540 C. The experiments were carried out using the method of testing one specimen with
successive partial unloading, which aims to r
occurs during the test. In addition to the experimental analysis, a numerical simulation of the
behavior of the specimens under static and dynamic loading was performed. The numerical analysis
is based on the experimentally obtained yield strength and tensile strength values of the investigated
steel, and was done in Ansys Workbench R21 software package, which relies on finite element
method, FEM. The results obtained by numerical analysis showed good agreement with the
experimentally obtained results of the J-integral for specimens tested at room and elevated
temperature. Good agreement with the experimental results was shown, confirming the use of FEM for the load cases considered.

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.

AB  - The first industrial application of elevated and high-strength steel in the form of hot-rolled strips and sheets
was the manufacture of pipes and vessels under pressure, as it was possible to reduce the thickness, i.e. to
reduce the weightof welded structures. The high-strength low-alloy steels used today are usually obtained by
suitable chemical composition and thermomechanical treatment.
Our investigated steel NIOMOL 490 K belongs to the class of molybdenum microalloyed steels, where the
microalloying with molybdenum serves to increase the heat resistance of the steel and at the same time
strengthen the influence of other alloying elements. This steel grade is designed for the manufacture of welded
pressure vessels fabrication and is mainly used for dynamic loading conditions at low operating temperatures.
In the present paper, the tensile and hardness tests were used to determine the effects of alloying elements
on the mechanical properties of NIOMOL 490K steel in the temperature range from -60°C to +60°C.

AB  - Pipelines, with specifics in design, construction, testing and safety requirements must be designed
based on all relevant influences to ensure that they are safe during their working life. Allowable
stresses must be limited by possible errors in working conditions, in order to completely eliminate
the uncertainty arising from the production, the calculation model, the actual working conditions and
the characteristics and behavior of the material. In the paper, on the example of modeling and
calculation of the corrosion-damaged structure of the ammonia (NH3) transfer pipeline, a
methodological approach to the calculation using the Finite Element Method (FEM), is shown, in
accordance with the methods defined by the new and general approach to standardization and
technical harmonization for pressure equipment (Pressure Equipment Directive - PED 97/23 EC).
The paper uses advanced modeling techniques of corroded surfaces, based on FEM, with the aim of
developing a procedure for assessing the residual strength of steel pipelines operating in the
environmental conditions of the chemical products industry. The presentation of possible damages
and consequences caused by the corrosion of steel pipelines in the chemical products industry is also

overview of the forms of corrosion that are most prevalent in welded joints is presented.
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.

AB  - The paper presents the technical solution for the foundation of the facilities of the
Boiler House for the energy utilization of waste and chimneys. Next to the boiler house, the
construction of a Bunker for waste storage is planned, which is founded at a depth of 6.0m below
the top of the boiler house's base plate. Based on the conditions of limited settlement, the
foundation of the boiler house was envisioned on drilled piles, while a hidden pile wall was
designed to protect the foundation pit of the bunker, which has the function of preventing large
deformations of the boiler house structure and does not jeopardize its stability. Calculations of the
bearing capacity of the piles based on the soil parameters from the geotechnical study are

Boiler House for the energy utilization of waste and chimneys. Next to the boiler house, the
construction of a Bunker for waste storage is planned, which is founded at a depth of 6.0m below
the top of the boiler house's base plate. Based on the conditions of limited settlement, the
foundation of the boiler house was envisioned on drilled piles, while a hidden pile wall was
designed to protect the foundation pit of the bunker, which has the function of preventing large
deformations of the boiler house structure and does not jeopardize its stability. Calculations of the
bearing capacity of the piles based on the soil parameters from the geotechnical study are
presented, as well as the results of the pile tests with axial vertical pressure force.",

AB  - Ponašanje struktura pod delovanjem različitih vrsta opterećenja
određene su njenim deformacionim karakteristikama, globalnim
deformacionim karakteristikama - pomeranjima i rotacijama i lokalnim
deformacionim karakteristikama - dilatacijama u osnovnom materijalu
strukture. Poznavanjem globalnih i lokalnih deformacionih karakteristika
strukture u toku njene eksploatacije ostvarujemo mogućnost da pratimo
ponašanje strukture u celini ili nekog njenog segmenta, kao i da u slučaju pojave
oštećenja, koja mogu nastati na osnovu različitih uzroka, pravovremeno
delujemo i sprečimo nastajanje havarijskih događaja koji kao posledicu mogu
imati kako ekonomske, tako i posledice sa ljudskim žrtvama.
Istraživanje u okviru ove disertacije obuhvata razvoj mernog
mehatroničkog sistema za nadzor ugiba grednih struktura praćenjem dilatacija u
osnovnom materijalu. Za utvrđivanje globalne deformacijske veličine
vertikalnog pomeranja - ugiba, na osnovu izmerenih lokalnih deformacionih
veličina, tj. posredno utvrđivanje ugiba strukture na njenoj ukupnoj dužini, na
osnovu poznatih vrednosti dilatacija u osnovnom materijalu strukture, usled
delujućeg opterećenja, razvijen je numerički postupak proračuna koji na osnovu
izmerenih vrednosti dilatacija u specifičnim tačkama na strukturi izračunava
vrednosti ugiba strukture, na celokupnom rasponu. Vrednosti dobijenih ugiba
primenom ovog postupka upoređene su sa vrednostima dobijenih putem direktnog
merenja ugiba na eksperimentalnim modelima i na realnoj strukturi.

Istraživanje je obuhvatalo tri faze:
1. Eksperimentalno ispitivanje na modelu čeličnog I nosača statičkog sistema
proste grede, direktno merenje ugiba usled nekoliko nivoa delujućeg opterećenja,
posredno izračunavanje ugiba primenom razvijenog numeričkog postupka
proračuna na osnovu izmerenih vrednosti dilatacija u osnovnom materijalu i
upoređenje vrednosti dobijenih na osnovu navedena dva postupka.
2. Eksperimentalno ispitivanje na strukturi nosača kranske staze pod delujućim
opterećenjem (realna struktura u eksploataciji), direktno merenje ugiba usled
delujućeg opterećenja, posredno izračunavanje ugiba primenom razvijenog
numeričkog postupka proračuna na osnovu izmerenih vrednosti dilatacija u
osnovnom materijalu i upoređenje vrednosti dobijenih na osnovu navedena dva
postupka.
3. Razvoj i provera rada mernog mehatroničkog sistema za nadzor ugiba grednih
struktura praćenjem dilatacija u osnovnom materijalu, u koji je implementiran

Kod prve dve faze istraživanja, kao i kod razvijenog mehatroničkog
sistema u koji je implementiran predloženi numerički postupak proračuna,
nisu zabeležene relativne razlike veće od 6 %, između direktno merenih i
posredno određenih vrednosti ugiba.

AB  - This paper focuses on the study of the strength of facade sandwich panels used in building construction. The paper describes the results of experimental and numerical research on the behavior of sandwich panels made of polyisocyanurate core (PIR) and their structural connections when exposed to tensile and compressive loads. In the initial phase of this study, laboratory tests were performed to determine the physical and mechanical characteristics of the material from which the sandwich panels are made. Laboratory tensile and compression tests were performed on small samples of sandwich facade panels. In order to verify the obtained results, they were compared with the numerical analysis performed in the ANSYS software. The numerical model was found to accurately predict the results of the laboratory tests, suggesting that the model can be used to predict the behavior of these panels under different loads in service. The study showed that the foam core sandwich panel exhibits excellent mechanical properties. The results indicate the suitability of foam-based composite structures in the construction industry for various applications, such as roof and wall structures. The findings of this study may help in the development of lightweight and durable construction materials for the industry.

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.

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 mechanical 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-Δa diagram. As the crack propagates, a point on the curve is defined, which represents the critical value of the J-integral. The aim of this experiment is to determine JIC value and the procedure is reflected in the determination of the R-curve, i.e., the J‒Δa curve, which consists of the value of the J-integral for uniform crack increments Δa. In this paper, precracked SEN(B) specimens with the fatigue crack positioned in the weld metal (WM) were tested according to standard ASTM E1820 at room temperature (RT), -20 °C and -30 °C.
