Cement plants grind clinker down to an extremely fine powder and mix in a few additives. The final result is cement. "Cement is then brought to sites where it is mixed with water, where it becomes cement paste," explains Professor Franz-Josef Ulm, faculty director of the MIT Concrete Sustainability Hub (CSHub).
It's important to realize that basic concrete contains just four ingredients: small rocks, sand, Portland cement and water. The cement is the glue or binder that holds the sand and rocks together.
