AB  - During the implementation of construction barrier design procedures for protection against gamma and X
radiation, the inevitable question arises of choosing building materials with suitable mechanical and radiation
characteristics for protective barriers. Based on engineering practice, it is necessary to compare different
types of concrete used for the construction of buildings in which there are sources of gamma and X radiation,
as in cases where radiation sources appear in medical institutions with linear accelerators, cyclotron
installations for the acceleration of nuclear particles, in the environment of nuclear reactors, in radioactive
waste warehouses or in radiation sterilization units. In the analysis of costs and benefits, several criteria are
used to evaluate the characteristics of concrete, so that, in addition to the mechanical ones, the radiation
characteristics of the building material are also taken into account. One of the most important characteristics
of radiation shielding concrete is its overall mass attenuation coefficient. In this paper, the XCOM computer
code was used to calculate the total mass attenuation coefficients in the energy range from 0.01 MeV to 100
MeV for three types of concrete: ultrahight properties concrete (UHPC), concrete with barite and concrete
with magnetite and steel. Based on the comparison of the calculation results, it was concluded that concrete
with magnetite and steel has a greater protective power than the other two types of concrete for gamma and X
radiation energy lower than 30 keV. Another important conclusion is that concrete with barite has a higher
protective power than the other two types of concrete in the photon energy range from 30 keV to 300 keV,
and for photon energy greater than 6 MeV. A detailed analysis of the calculation results revealed that in the
energy range from 400 keV to 6 MeV the values for the total mass attenuation coefficients are approximately
the same for three different types of concrete.

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  - 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  - A comparative study of performances of self compacting concrete (SCC) with fly ash and limestone filler was conducted. The experimental program included the production of reference SCC designed with Portland cement, river sand and limestone filler and four experimental self compacting concretes with different types of fine aggregates, fillers and special additive to increase freeze-thaw resistance. The effects that different sand and additions have on the properties of fresh SCC (slump-flow test, V-funnel test, and L-box test) and compressive strengths in early ages (3 and 7 days) were investigated and discussed.
