bauxite in concrete

Understanding the Difference Between Cement and Concrete

There are four primary ingredients in concrete: cement, stone, sand, and water. The less water that is added to a concrete mixture, the stronger that mixture will be. The water used in concrete activates the cement, which acts as the binding agent. Aggregates (coarse and fine) in the mix are bound together by the cement.
