Concrete Definition: Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate (sand, gravel, stone, brick chips, etc.), water, admixtures, etc in specific proportions. The strength and quality are dependent on the mixing proportions.

Concrete is made up of three basic components: water, aggregates (such as sand, gravel, and crushed stone), and Portland cement. In addition to these three main ingredients, concrete may also contain admixtures to modify setting times and enhance strength and workability. This combination of materials is much stronger and more durable than ...
