Rapid Hardening Cement All You Need to Know Civil

Rapid Hardening Cement (RHC) is a certain type of Portland cement typically used in concrete construction to develop high strength earlier than Ordinary Portland Cement (OPC). According to AASHTO M 85 specification and ASTM C 150 standard specification for Portland cement, RHC is a type-III cement also called High Early Strength cement.

Rapid Hardening Cement-Definition, Application and Use

Jul 20, 2019· Rapid hardening cement develops at the age of three days, the same strength as that is expected of ordinary Portland cement at seven days. The rapid rate of development of strength is attributed to the higher fineness of grinding (specific surface not less than 3250 sq. cm per gram) and higher C3S and lower C2S content.
