    Hardening Cement (RHC) ... Burning and Grinding. After mixing the materials in appropriate proportions, the mixture is burned at a high temperature. Here the chemicals go through some reactions and are turned into calcium silicates which form the cement clinker. The cooled pellets are then ground in ball mills or tube mills and during this grinding process, a small proportion of gypsum ...

    This hardening is a process of crystallization. Crystals form (after a certain length of time which is known as the initial set time) and interlock with each other. Concrete is completely fluid before the cement sets, then progressively hardens. The cement and water mixture that has crystallized in this way encloses the aggregate particles and produces a dense material. The concrete continues ...

The cement thus produced is so fine that it almost completely passes through 0.075mm sieve ...
