Raw materials Understanding Cement

If the 'good stuff' is all used up first, it may be more difficult to make cement out of what is left. Careful selection on a day-to-day basis is needed to make the best use of all the materials available. Raw materials are extracted from the quarry, then crushed and ground as necessary to provide a fine material for blending.
