Cement is a fine grey powder that is mixed with gravel, sand, and water to form concrete, the most widely used construction material in the world. Cement and supplementary cementing materials (SCMs) are the critical ingredients that lock sand and gravel together into an inert concrete matrix. They typically represent 10% to 15% of a concrete mix.
