The production process for cement is a mix of traditional chemistry and hi-tech equipment. Cement is a hydraulic bonding agent which is obtained by heating, then grinding, a mixture of limestone and clay. Most cements are made from clinker and additives and are usually used in the form of a powder. Cement sets when mixed with water.

Concrete is a mixture of cement, air, water, sand, and gravel-it's as simple as that! Not exactly. The typical concrete mix is made up of roughly 10% cement, 20% air and water, 30% sand, and 40% gravel. This is called the 10-20-30-40 Rule-though proportions may vary depending on the type of cement and other factors.
