    Abstract. On the basis of the result analysis of the research conducted at NIIZHB named after A.A. Gvozdev in different years, domestic and foreign experience, the article makes recommendations on the normalization of hydro-physical (density, water absorption, humidity), strength (cube and prismatic strength, strength at axial tension and bending), deformation (modulus of elasticity under compression and tension, Poisson's ratio, limiting compressibility and extensibility) and thermo-physical (coefficient of thermal conductivity at different humidity, sorption humidity, steam permeability) properties and as well as the durability(frost resistance, corrosion resistance, alkaline corrosion) of low thermal conductivity concretes of D300:D700 density with glassy fillers. The results of tests of structural elements (beams and columns) from lightweight concrete with granular foam glass are given. The possibility of using lightweight concrete with a glassy porous filler in flexural and compressed structural elements has been confirmed. An area of application of concretes with glassy fillers when constructing buildings of up to 5 storey height and their overlappings is recommended.
    Key words: light concrete, glassy porous filler, mechanical strength, deformation properties, thermo-physical characteristics, durability, frost resistance, calculation, bearing capacity.
