MECHANICAL ACTIVATION PROCESSING OF A FILLER FOR FINE-GRAINED CONCRETE QUALITY IMPROVEMENT
DescriptionThe results of research of influence of mechanical activation of filler (river sand) on physical, mechanical and structural properties of fine-grained concrete are presented in the article. The prospects of using mechanical activation technologies for production of concrete with the improved complex of technical characteristics are established

RESEARCH OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE DISTRIBUTION IN POLYMERELASTOMER COMPOSITE
DescriptionThe research of distribution of polyethylene in production of composites on a basis of butadiene - nitrile rubber and ultra high molecular weight polyethylene is presented in this work. The raised content of polyethylene on the surfaces of samples and products that causes surface effect of modifying and improvement of agressiveproof property and wears resistance is established

STRUCTURE AND SPECTRAL-LUMINESCENT PROPERTIES OF THE SILICATES OF RARE EARTHS WITH APATITE STRUCTURE
01.00.00 Physical-mathematical sciences
DescriptionCaGd4 x y zYbxEryCez(SiO4)3Osingle crystals were grown by the Czochralski method, the concentration dependence of the luminescence decay kinetics of the levels 4S3 / 2, 4I11 / 2 and 4I13 / 2 ions Er3+and X-ray analysis conducted for these crystals. By the results of stereo atomic analysis, it is shown that there is possible to estimate the lifetimes of levels, i.e. predict the probability of multipole interactions

CASCADE PHOTON EMISSION IN LUMINOPHORES AND STEREOATOMIC ANALYSIS
01.00.00 Physical-mathematical sciences
DescriptionThe relation between degree of sphericity of the Voronoi-Dirichlet’s polyhedron G3 and the ability to demonstrate the first stage of the cascade luminescence of Pr3+ for several crystalline fluorides and oxygen-containing compounds was revealed. It was found that LaZr3F15 and BaSiF6, with energy level 1S0 located below the bottom of 5d-band, which demonstrate cascade luminescence have the smallest value of G3 among investigated compounds
