What is concrete

Concrete is the second most consumed substance on Earth after water! A world without concrete is almost inconceivable!

Concrete is a mixture of sand, gravel and/or other aggregates (the matrix), bound together by a water-based binder, cement. Admixtures (modifying agents) and additives (fine mineral powders) are sometimes introduced to improve the characteristics of the fresh concrete, of the mixing process and/or of the final hardened material.
