Abstract

Oppfinnelsen tilveiebringer et tilsetningsmiddel for å nedsette vanninnholdet i en betongblanding. Tilset- ningsmidlet omfatter en alkalisk oppløsning av et lig- nin i sulfometylolert form. Det Sulfometylolerte lig- nin i tilsetningsmidlet kan også være forenettet med et fornetningsmiddel. Tilsetningsmidlet omfatter også en luftfjerner. Det er også tilveiebrakt nye sementblan- dinger omfattende tilsetningsmidler ifølge oppfinnelsen.
