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.
