What is cement?

Cement is the main component of concrete. It's an economical, high-quality construction material used in construction projects worldwide. Cement is made by grinding together a mixture consisting mostly of limestone and aluminium and silica oxides, which is heated at a temperature of 1,450°C. The result is a granular substance called "clinker," which is then ground into the fine gray powder called cement.

National Cement manufactures and markets various types of cement, based on the chemical composition of the raw materials used and the grinding process. Each cement type has specific applications. These include residential construction, civil engineering structures, underground work and the production of concrete for harsh environments or for highly corrosive conditions.
