However, there are other synonyms for Portland Cement that can also be used: Ordinary Portland Cement (OPC), High Early Strength Portland Cement (HE), Rapid Hardening Portland Cement (RHPC), Low Heat Portland Cement (LHPC), and Sulphate Resisting Portland Cement (SRPC). OPC is the most commonly used synonym for Portland Cement in construction and is suitable for a wide range of applications such as concrete, mortar, and plaster. HE, RHPC, LHPC, and SRPC are specialized types of Portland Cement used for particular construction needs, such as high strength, fast setting, low-heat generation, and sulphate resistance.
