Ordinary Portland Cement (OPC) is the most commonly used cement in the construction field. It is a basic type of cement that mainly includes clinker (which is calcined limestone and clay) and gypsum. The name “Portland” comes from its similarity to Portland stone, a popular building stone in England.
Even though OPC is very popular, it’s worth mentioning that there are other specialized cements like Portland Pozzolana Cement (PPC) and Portland Slag Cement (PSC), each having distinct features that make them suitable for different uses. The type of cement chosen depends on what the construction project needs and the specific qualities desired in the concrete.
