Abstract
Oppfinnelsen vedrører anvendelse av kalkhydrat for akselerering av trykkfasthetsutviklingen hos portlandsement. Ifølge oppfinnelsen tilsettes det til en bindemiddel-sammensetning for hydraulisk herdende sammensetninger fra 1 til 10 vekt% kalsiumhydroksid med en BET-overflate på fra 7 til 16 cm2/g regnet av sementen.The invention relates to the use of lime hydrate for accelerating the compressive strength development of Portland cement. According to the invention, a binder composition for hydraulically curing compositions is added from 1 to 10% by weight of calcium hydroxide having a BET surface of 7 to 16 cm 2 / g calculated by the cement.
