OPC (Ordinary Portland Cement)

Ordinary Portland Cement (OPC) is the most widely used type of cement in the construction industry. It is a basic form of cement that primarily consists of clinker (calcined limestone and clay) along with gypsum. OPC is named "Portland" because of its resemblance to Portland stone, a type of building stone that was widely used in England.

While OPC is widely used, it's important to note that there are other specialized types of cement, such as Portland Pozzolana Cement (PPC) and Portland Slag Cement (PSC), each with unique properties suited for specific applications. The choice of cement depends on the requirements of the construction project and the desired properties of the concrete.
