Abstract: The article presents the results of studies of the effect of a modifier based on silica fume, a superplasticizer based on polycarboxylate ether, expanding additives based on industrial waste and the shrinkage reducing admixture SRA on the properties of concrete mixtures and concrete. The effect of the complex modifier on the compressive strength of concrete aged 7, 28, and 90 days of normal hardening was investigated. The data on the influence of the developed modifier on the indicators of moisture shrinkage deformation of concrete are analyzed. Data on the effect on frost resistance and water tightness of heavy cement concrete with expanding mineral additives are obtained.

Keywords: concrete durability, shrinkage deformations, expanding additives, shrinkage reducing admixture SRA, compressive strength, frost resistance, water resistance.
