Hydration of Portland Cement Penn State EngineeringPortland cement ScienceDirect

Portland cement is a hydraulic cement hence it derives its strength from chemical reactions between the cement and water The process is known as hydration The process is known as hydration Cement consists of the following major compounds see composition of cement The production cost of Portland cement is closely linked to the cost of the fuel used to create a kiln temperature sufficiently high to enable the different chemical reactions that
