- Cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together. Portland cement is the most common type of cement in general use around the world. Portland cement was developed from natural cements made in Britain. Its name comes from its similarity to Portland stone, a type of stone on the Isle of Portland in England.
- Cement made by heating clay and crushed limestone into a brick and then grinding to a pulverized powder state.
EXAMPLE:
Concrete is a mixture of Portland cement, sand, gravel and water.
