Clinker

Clinker is the basic, raw material used in the production of all types of cement and the one that bestows upon cement its hydraulic properties. Clinker is obtained by burning a mixture of approximately 80% of limestone and 20% of clay at high temperatures through chemical reactions; clinker occurs as spheroidal nodules 10-25mm in diameter, with high hardness. The quantity of clinker in cement could be reduced by adding alternative materials, called cement additives.
