【 摘 要 】

Polystyrene concrete blocks are effective structural and thermal insulating wall material, but the matrix structure of the clinker reduces thermal properties, and long hardening of the cement leads to a long cycle of their manufacture. To solve these problems is propose to use instead of the cement composite binder with liquid glass and cullet, which has low thermal conductivity like a material in amorphous phase. The high electrical conductivity of liquid glass makes it efficient to use the method of electric heating. Electric heating and self-compacting energy of polystyrene granules allow to accelerate the hardening of the compound, to increase the strength of the structure, to reduce the technological cycle and energy intensity of the production. In this case the absence of prolonged high temperature treatment allows to efficiently recycle waste glass as a main component of the mixture, improving the properties of the product and reducing its cost.
