Cement is a binder that, when mixed with aggregate (sand and gravel) and water, forms concrete; one of the world’s most versatile and durable construction material. Step 1 - Raw material preparation Limestone and silica sand are blended with additional minerals into a finely ground powder. Step 2 - Clinker production The finely ground powder is heated in a kiln producing a molten product called clinker. Step 3 - Cement grinding and distribution The clinker is mixed with additional materials, depending on the type of cement being made, then ground to a fine powder. |
