Some Questions of Shrinking Concrete Deformations with Extending Additive on Porous Fillers in Kabardino-Balkaria

Abstract

The article is devoted to the study of the light concrete shrinkage deformations’ development patterns on porous aggregates of the volcanic tuff Kamensky deposit in Kabardino-Balkaria, prepared on quartz and tuff sands, using an expanding additive of sulfo-aluminate type in the amount of 12.5% Portland cement mass, the composition and amount of which was determined by the DSTU method.
