Abstract
The invention relates to building materials, particularly to compositions of complex additives, used in production of concrete mixtures and mortars. A chemical additive contains components in the following ratio, wt. %: sodium thiosulphate – 10.0-68.0, sodium rhodanite – 10.0-68.0, sodium sulphate – 26.33-80.0. The invention provides the preparation of high-efficiency chemical additive, providing the increasing concrete initial strength and allows placement of concrete in conditions of low temperatures.
