gypsum limestone in cement

gypsum limestone in cement - MC World

4/11/2011 The key difference between gypsum and limestone is that the calcium sulfate is the main constituent in gypsum whereas calcium carbonate is the main constituent of limestone.. Limestone and gypsum are minerals that form from calcium salts; limestone contains calcium carbonate while gypsum contains CaSO 4 2H 2 O.

Addition of limestone at the expense of gypsum in

2018-9-5  The influence of the addition of limestone at the expense of gypsum in Portland cement was investigated. Results showed that with the gradual replacement of very fine limestone instead of gypsum the hydration process improves, enhances at all curing times until 90 days. On this basis, the hydration heat, bound water, free lime contents, bulk density, compressive strength improved, were ...
