Clinker chemical reaction
WebClinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. When limestone is converted to clinker, CO 2 … WebCement is a manufactured product. Clinker is manufactured from raw materials and then ground into cement. Cement is hydraulically active and will react with water. This reaction is a chemical reaction that will generate heat and CSH gel which gives the set slurry its properties of a low permeability solid with compressive strength.
