Clinker: combinability of mixes - Understanding Cement

Clinker: combinability of mixes. The ease of combination ("combinability", or "burnability") is about how easily the raw materials react with each other in the kiln to produce the clinker minerals. Clinker composition is evidently one of the key factors which determine cement quality. Composition is controlled mainly by suitable blending of raw ...
