Production technology and properties of polystyrene concrete on recycled polystyrene

Abstract

The article deals with the production of polystyrene concrete from recycled polystyrene crushed in a rotary crusher waste from the production of foam packaging. The resulting polystyrene concrete can be attributed to thermal insulation, used for insulation of load-bearing structures of buildings, as well as to structural and thermal insulation, used as a bearing layer of the outer walls of low-rise buildings. The dependence of the thermal conductivity of the sample on the density and strength of polystyrene concrete has been established, and the resistance to shock loads depends not only on the composition but also on the polystyrene concrete hardening accelerator used.
