Influence of Silica Sol on Physico-Mechanical Properties of Polystyrene Concrete

The article discusses the use of silica sol obtained by salt hydrolysis, to improve the physical and mechanical properties of the cement and polystyrene concrete. Improvement the properties of cement with colloid additive and changing phase composition are proved. The composition is designed and main characteristics of polystyrene concrete are defined with silica sol and naphthalene superplasticizer. The optimal dosage of the sol in the composition of polystyrene concrete is identified. It is proved that with use of modifying additives – silica sol the hydrophilicity of foam polystyrene to the cement stone increases in the composition of polystyrene concrete. Compressive strength of polystyrene concrete is increased with a decrease in average density.
