The role of gypsum in cement
Role of gypsum in cement In the absence of gypsum, the reaction of C3A in ground clinker (cement) with water is very rapid. The C3A is converted to calcium aluminates hydrate (4CaO.Al2 O3.19H2 O), which forms interlinking bridges of solid material between the cement particles.
