Influence of gypsum fineness in the first hours of cement
In the present study, the rheology test was used to determine the influence of gypsum fineness in the first few hours of cement hydration. The analysis of the hydration and rheological behaviour of cement pastes with the addition of fine, medium, and coarse gypsum made it possible to measure the influence of gypsum fineness on the cement paste. 2.
