AB  - This study compared the performance of self-compacting concrete (SCC) based on fly ash addition and limestone filler. A SCC prepared with Portland cement, river sand, and limestone filler was used as a reference sample. Additional experimental self-compacting concretes with different types of fine aggregates, fillers, and special additives for increasing freeze-thaw resistance were prepared and optimized. The correlation between mix design, i.e., percentage of barite sand and additives, on properties of hardened SCC (compressive and flexural strengths), were investigated and discussed.

AB  - Self-compacting concrete (SCC), a non-shaped composite building material, has
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
focus of these articles.

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  - The paper shows the influence of steel fibers obtained from steel wire separated in the recycling process of waste car tires on the properties of concrete. The reference concrete was prepared, as well as concretes with the addition of steel fibers, which were varied in contents at 20 kg/m3 and 40 kg/m3. The slump test of fresh concrete was performed using the Webe method, where it was established that with an increase in the amount of fibers, concretes with a stiffer consistency are obtained. Concrete beams were tested for strength during flexure tension (limit of proportionality (LOP) and residual flexural strength).
Can be concluded that the residual flexure strength greater than 1.5 MPa at a CMOD of 0.5 mm is already achieved with the addition of 20 kg of fibers per m3 of concrete, while both conditions for the residual bending strengths are satisfied with the addition of 40 kg of fibers per m3 of concrete and that they amount to 2.4 MPa at a CMOD of 0.5 mm and 1.4 MPa at a CMOD of 3.5 mm.

All concrete samples were made  with  same component materials and compositions, except for the amount of fibers, which was varied. After hardening, the concrete samples were tested for compressive strength, tensile splitting strength and water penetration depth under pressure. Based on the test results, depending on the type, shape, amount and arrangement of fibers, the tensile and compressive strength values as well as the depth of water penetration under pressure were analyzed. Based on the tests performed, the best mechanical properties were achieved with the use of "Dramix 3D" steel fibers.

AB  - The impacts of nano-silica addition, steel micro-reinforcement, and aggregate type on the mechanical properties and durability of ultra-high-performance concrete (UHPC) were studied. As aggregates, quartz and barite were used. The amounts of steel fibers and nano-silica were alternated. Six concrete mixes were produced with quartz sand, and the remaining six concrete mixes were designed with barite sand. Fibers made about 3-5% of the concrete composition’s mass. In a 2-5% concentration, nano-silica was used as a cement replacement. The inclusion of nano-silica significantly boosted the compressive strength of UHPC. The compressive and flexural strengths were also positively impacted by fiber supplementation ranging from 3% to 5%. The amount of fiber utilized proved to be more influential than the aggregate used. The UHPC concrete's durability was increased as all samples were highly resistant to freezing and thawing cycles. UHPC designed with barite aggregate demonstrated good X and gamma ray absorption at energies below 300 keV.

AB  - The phyllosilicate mineral pyrophyllite can be utilized in cementitious composites design to replace quartz powder and boost workability, early strengths, and refractoriness. Employed as a mineral additive or microfiller, pyrophyllite is stable at high temperatures owing to its thermal conversion into mullite.
In this study, mortar samples were prepared using andalusite as aggregate, high-alumina cement as a binder, and pyrophyllite as an additive (15%, 25%, and 35%). Compressive and flexural strengths, both at normal and elevated temperatures (samples were thermally treated at 1000°C) were tested on the samples, along with the refractoriness. The effects of pyrophyllite addition on the mineral composition, microstructure, and bonding and sintering mechanisms were studied using instrumental analytical techniques. Pyrophyllite acted as additional pozzolana during cement hydration as it formed microreinforcement
in the shape of crystalline folia within the microstructure, which improved the
compressive strengths of mortars. The differential thermal analysis highlighted that pyrophyllite did not negatively interfere with the cement hydration route; moreover, this mineral additive behaved as pozzolana. The investigation demonstrated that pyrophyllite additions of up to 25% can be used in cementitious composites without affecting their performance.

AB  - During the implementation of procedures for designing building barriers for protection against gamma and X radiation, the unavoidable question of choosing construction materials with appropriate mechanical and radiation characteristics for protective barriers arises. Based on engineering practice, it is necessary to compare different types of concrete used for the construction of facilities where there are sources of gamma and X radiation, such as in cases where radiation sources appear in medical facilities with linear accelerators, cyclotron installations for accelerating nuclear particles, in the environment of nuclear reactors, in radioactive waste storages, or in radiation sterilization unit s. In the cost-benefit analysis, several criteria are used to evaluate the characteristics of the concrete, so that in addition to the mechanical characteristics, the radiation characteristics of the construction material are also considered. One of the most important characteristics of concrete for radiation protection is its total mass attenuation coefficient. In this paper, computer code XCOM was used for the calculation of the total mass attenuation coefficients in energy range from 0.01MeV to 100 MeV for three types of concrete: ordinary concrete, concrete with barite and concrete with limonite and steel. Based on the comparison of calculation results, it was concluded that concrete with limonite and steel has greater protective power than other two concrete types for the gamma and X radiation energy less than 30 keV. The second important conclusion is that the concrete with barite has greater protective power than other two concrete types in the range of photon energy from 30 keV to 300 keV, and for photon energy greater than 6 MeV. A detailed analysis of the calculation results found that in the energy range of 400 keV to 6 MeV values for the total mass attenuation coefficients are approximately the same for three different types of concrete.

AB  - The experimental study included the design and production of ultra-high-performance steel fiber-reinforced concrete (UHPFRC). The physical and mechanical properties of UHPFRC were investigated in a laboratory setting. To investigate the properties of UHPFR concrete, three types of concrete and over 70 samples were used. Following that, samples were created to test the anchors' load-bearing performance. Six concrete slabs with a total of 108 pre-installed anchor samples and six concrete slabs with 108 post-installed chemical anchor samples were created. The analysis of the test findings comprised all individual results as well as the definition of the relationship between the anchor's tensile load capacity and other parameters. To accurately determine the individual influence of the investigated factors as well as their combined impact, a factorial experiment, and artificial neural networks were used in addition to normal statistical numerical studies. It was determined that both approaches offer advantages. The results obtained show matches in certain parts. Due to the way data is processed in different ways, there are also significant differences between them.

AB  - Compared to traditional concrete, self-compacting concrete (SCC) demonstrates greater flowability, which is achieved by including an extra high percentage of ultra-fine particles. As a result, the required high paste content is obtained while the cement content is strictly limited. The coal combustion byproduct (fly ash) is one of the most efficient SCC fillers because it extends the lifecycle of SCC by improving its microstructural properties, strength, and durability. In this study, the amounts of fly ash in SCC compositions varied. The changes in physical and mechanical characteristics of fresh SCC samples related to variations in the water/binder ratio were monitored.

AB  - Tehničko rešenje predstavlja poboljšanu konstrukciju zaštićene grejne ploče (hotguarded plate) za merenje toplotne provodljivosti termoizolacionih materijala
postavljanjem ispitnog uzorka iznad i ispod grejne ploče (standardna simetrična
ispitna konfiguracija). Merenje toplotne provodljivosti vrši se u skladu sa
standardom SRPS U.A2.020.
Ovim rešenjem toplotna provodljivost se proračunava na osnovu vrednosti
izmerenog toplotnog fluksa korišćenjem dva tanka toplotna fluksmetra na toploj
i hladnoj strani ispitivanih uzoraka. Prednost korišćenja fluksmetara na grejnoj i
rashladnoj ploči u odnosu na uobičajen metod za određivanje toplotne
provodljivosti (hot-guarded plate) je u periodu dostizanja stacionarnog stanja koji
je znatno kraći. Na taj način bi se ostvarila sva zahtevana merenja toplotne
provodljivsti termoizolacionih materijala usled povećane potražnje za ovakvom
vrstom ispitivanja u Republici Srbiji.
Kod metoda merenja sa toplotnim fluksmetrima, uobičajeno je da se koristi jedan
fluksmetar na zaštićenoj grejnoj ploči. Kod ovog tehničkog rešenja koriste se dva
toplotna fluksmetra na površini uzorka. Na taj način se precizno može utvrditi
srednja vrednost toplotnog fluksa kroz ispitivani uzorak tj. srednji toplotni fluks
kroz sam uzorak je tačnije određen. Fluksmetri za ovakvu vrstu merenja su
odabrani sa velikom mernom površinom da bi se dobile što merodavnije
vrednosti raspodele toplotnog fluksa po mernoj površi, pri čemu uobičajeno
korišćenje znatno manjih toplotnih fluksmetara.
Novi koncept grejne ploče ne odgovara uobičajenim grejnim pločama koje su
opisane u standardima. Specifičnost ovog dizajna ploče je u smanjenom
toplotnom prekidu – prostor između unutrašnje zaštićene (hot) i spoljašnje
zaštitne (guard) ploče koje zajedno čine predmet ovog tehničkog rešenja.
Veličinom toplotnog prekida od 1 mm popunjenog dvokomponentnim
termoizolacionim lepkom, određena je i minimalna dozvoljena debljina uzorka. 
Na taj način je omogućeno merenje tanjih termoizolacija, tj. povećan je merni
opseg samog uređaja pri ovakvom načinu izrade grejne ploče.
Dodatna prednost u pogledu konstrukcije toplotnog prekida je u formiranju
stepenika čija je osnovna svrha formiranje jednodelne konstrukcije koja se sastoji
od zaštićene (hot) i spoljašnje zaštitne (guard) ploče. Uobičajeno se ovakve ploče
izrađuju iz više segmenata dok je specifičnost ove konstrukcije da se sastoji iz
jednog dela.
Temperaturska razlika između dve ploče se kontroliše korišćenjem termoparova
u diferencijalnom spoju koji su raspoređeni po obimu kontakta dve ploče.
Merenjem naponskog signala za praćenje temperaturne razlike između pomenute
dve ploče mogu se proceniti lateralni gubici između zaštićene i zaštitne ploče i
izmereni naponski signal se može koristiti u svrhe upravljanja.
Grejači zaštićene i zaštitne ploče su ukopani u materijal grejne ploče i napravljeni
su korišćenjem žice za izradu termoparova K tipa. Grejači su vezani na standardni
priključak za termoparove tipa K, koji je fiksiran za grejnu ploču. Preko fiksiranih
priključaka ostvareno je napajanje grejača naponskim dvokanalnim nezavisnim
izvorom. Korišćene su rashladne ploče koje su hlađene korišćem automatzovanog
rashladnog kupatila sa propisanom površinskom fluktuacijom temperature
rashladne površi od 0,1°C.
Validacija grejne ploče je izvršena učešćem u međulaboratorijskom poređenju.

AB  - The Guarded hot plate method (GHP) 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 guarded hot plate 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 guarded hot plate 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℃. 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  - Concrete in which the air entraining admixture was used can exhibit behavior which alternate from the ‘standard’ concrete behavior when employed in the structural design. The origin of this problem can be found in the changeable properties of the componential materials, incompatibility of the utilized raw materials, influence of extreme conditions on the concrete curing (i.e., increased temperature), etc. The possibility of using other additives for the concrete exposed to various environmental influences was investigated. Sustainability of concrete production and resource efficiency urged the searching for an adequate waste material or an industrial byproduct which would improve freezing/thawing resistance of concrete. In this paper the possibility of Sika Aer Solid powdery additive and recycled rubber as a substitute for the air entraining admixture was investigated. Four mixtures were designed: referent concrete with no air entraining admixtures, concrete with Sika Aer Solid, concrete with recycled rubber, and concrete with air entraining admixture. The properties of fresh and hardened concrete were examined. The obtained results of compressive strength, resistance to freezing/thawing cycles and depth of water penetration under pressure for altered concretes indicate that it is possible to use alternative additives as substitutes for air entraining admixture.

The origin of this problem can be found in the changeable properties of the componential materials, incompatibility of the utilized raw materials, influence of extreme conditions on the concrete curing (i.e., increased temperature), etc. The possibility of using other additives for the concrete exposed to various environmental influences was investigated. Sustainability of concrete production and resource efficiency urged the searching for an adequate waste material or an industrial byproduct which would improve freezing/thawing resistance of concrete. In this paper the possibility of Sika Aer Solid powdery additive and recycled rubber as a substitute for the air entraining admixture was investigated. Four mixtures were designed: referent concrete with no air entraining admixtures, concrete with Sika Aer Solid, concrete with recycled rubber, and concrete with air entraining admixture. The properties of fresh and hardened concrete were examined. The obtained results of compressive strength, resistance to freezing/thawing cycles and depth of water penetration under pressure for altered concretes indicate that it is possible to use alternative additives as substitutes for air entraining admixture.",

the same component materials and composition, except for the amount of fiber,
which is varied. After hardening, the height of the concrete beams in the central
part was reduced to 125 mm by cutting. The measurement of flexural tensile
strength by was performed according to SRPS EN 14651. Based on the test
results, depending on the type, shape, quantity and distribution of fibers, the

AB  - Self-compacting concrete (SCC) exhibits increased flowability in comparison with the conventional vibrated concrete. This is most often achieved through the incorporation of high amounts of extra-fine particles (i.e. mineral fillers) in the composition of self-compacting concrete. The purpose is to limit the share of cement while reaching the required large paste content. The components and their proportions, as well as type and particle size of filler, casting, manufacturing and curing conditions of SCC, significantly influence the concrete’s fresh and hardened properties. Among fillers employed in SCC, fly ash is one of the most frequent due to its availability and the low cost. Fly as is an industrial by-product and a highly efficient mineral additive whose role is reflected in improvements of microstructure packing, strength and durability of non-shaped composite building materials such as self-compacting concrete. A comparative study of performances of SCC with different quantities of fly ash and standard SCC with limestone filler was conducted in this study. The experimental program included the production of reference self-compacting concrete based on Portland cement and limestone filler (P1) and additional three experimental self-compacting concrete mixtures (P2, P3, P4) with different quantities of fly ash addition. Behaviour of self-compacting concrete in the fresh state is primarily influenced by type of mineral additive used. The effect that fly ash addition has on the physical behaviour and mechanical properties of fresh experimental SCC concrete samples was discussed. The properties and technology of self-compacting concretes in their fresh state in regard to the alternations in water/cement (w/c) ratios are monitored and explained in this paper. Concrete mixtures with fly ash had lower density in comparisons with the referent concrete. For the same class of consistency, higher amount of water was needed for preparation of SCC mixture with fly ash. Increasing w/c ratio induced more favourable properties of self-compacting concrete in its fresh state.

sprayed concrete is presented in the paper. Fibres of different materials, shapes and dimensions were used. All types of
concrete were made of the same component materials and composition, except the amount of fibres that is varied. Slabs
of dimensions 60x60x10 cm were made using a concrete spraying machine. After curing, the beams of 75x125x500 mm
were cut from the beams. Flexural strength of the beams was tested according to SRPS EN 14488-3 at the age of 28
days. Based on the test results, depending on the type, shape, amount and distribution of fibres, values of ultimate and
residual strengths were analysed. The highest values of ultimate and residual strength at deformations of 0.5-1, 0.5-2 and
0.5-4 mm had sprayed concrete (or shotcrete) with the addition of 40 mm polypropylene fibres.
