Hydration of calcium sulphate hemihydrate. II. Acceleration by neutral salts

Abstract

Abstract A study has been made of the effects of accelerating salts on the hydration of calcium sulphate hemihydrate. Univalent cations could be arranged in the following order of effectiveness Li + < Na + , NH , < K + > Rb + > Cs + . Anions tested showed the following order of effectiveness. CI − , Br − , I − , CNS − , NO < F − < SO .
