Abstract

Oppfinnelsen tilveiebringer en blanding for å nedsette vanninnholdet i en betongblanding. Tilsetningsmidlet omfatter en alkalisk oppløsning av et lignin i sulfometylolert form. Blandingen omfatter ytterligere en luftfjerner. Det er også tilveiebrakt en ny sementblanding omfattende et tilsetningsmiddel ifølge oppfinnelsen.The invention provides a mixture for reducing the water content of a concrete mixture. The additive comprises an alkaline solution of a lignin in sulfomethylated form. The mixture further comprises an air remover. Also provided is a new cement composition comprising an additive according to the invention.
