FIELD: construction.
SUBSTANCE: plasticising additive to a concrete mix comprises aqueous solution of technical pentaerythritol, 40% aqueous solution of sodium polyacrylate. The mass ratio of the specified sodium polyacrylate and pentaerythritol is 100:1. The specified components in the additive are contained in the form of a compound.
EFFECT: increased mobility and accelerated concrete hardening in wide range of temperatures, including negative, higher concrete strength and prevention of corrosion of metal reinforcement.
