The Cement Manufacturing Process

The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction.

How Cement is Made

The clinker keeps cooling and a ball mill grinds it with gypsum or other ingredients into fine cement—about 150 billion grains per pound. Blending in higher ratios of limestone or SCMs can reduce a plant's carbon footprint by up to 10%.
