What is the difference between cement and concrete?

Increasingly we hear the terms cement and concrete used interchangeably however cement is actually an ingredient of concrete. Concrete is basically a mixture of cement, sand, either 4/10mm or 4/20mm aggregate and water.

Cement is the active ingredient in concrete. Through a process called hydration, the cement when combined with water hardens and binds the aggregates into a rocklike mass. This hardening process continues for a few weeks meaning that concrete gets stronger as it gets older.

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete. It was developed from other types of hydraulic lime in England in the late 19th century by Joseph Aspdin.

Cement is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of Portland cement are available. The most common, called Ordinary Portland cement (OPC), is grey in colour.
