Abstract
The paper deals with the process of production and properties of foam glass concrete – a composite material consisting of modified gypsum binder and granulated foam glass as an aggregate. Foam glass concrete has high strength, durability, environmental friendliness and low thermal conductivity, which makes it a promising material for wall structures. Optimal packing densities were obtained by using programs developed by the authors in the Python programming language to calculate the optimal diameters of three fractions of granular foam glass in an orthogonal or hexagonal packing model. The compressive and flexural strength and thermal conductivity coefficient were investigated on samples of different compositions. The value of the thermal conductivity coefficient of the foam glass concrete was reduced due to the air-entraining additive. In conclusion, the optimum composition of foam glass concrete was proposed taking into account all investigated parameters.
