The article presents the results of physical-structural, chemical, mechanical and radiation attenuation measurements γ conducted for various concrete structures with polymer sulfur. A scanning electron microscope and the LIBS system – the method of atomic emission spectroscopy with laser excitation – were used for structural and chemical composition studies. Tests of mechanical properties were carried out on an Instron 8862 testing machine, while the determination of the absorption coefficient of radiation γ was carried out in a measuring system with sources: 137Cs and 60Co, as well as natural γ-ray sources, comprising uranium minerals: autunite Ca[(UO2)(PO4)]2(H2O)11, uranophane Ca(UO2)2(SiO3OH)2 · 5H2O and uranite UO2 - UO3. The study highlighted the highly favorable structural and physicochemical properties of sulfur concrete compared to conventional concrete. The results of compressive strength tests showed that sulfur concrete has equivalent properties to C55. The results of radiation attenuation tests of sulfur concrete specimens with suitable fillers showed significantly higher linear attenuation coefficient values compared to classic concrete.
