2011-7-25Chemical Composition Sulfate-resisting Portland cement clinker consists predominantly of compounds formed from calcium silica alumina and iron. Calcium sulfate is present in cement due to the gypsum addition to control setting time. Specific chemical data e.g

Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement. Cement Wikipedia

Cement is a hydraulic binder and is defined as a finely ground inorganic material which when mixed with water forms a paste which sets and hardens by means of hydration reactions and processes which after hardening retains its strength and stability even under water
