Cement Manufacture - an overview ScienceDirect Topics

The dry process of cement manufacture is most often used, but some plants utilise the wet process, which avoids the necessity of drying the slag. In Germany the slag is used both in the manufacture of the Portland cement clinker by the dry process and for grinding subsequently with the clinker to form the Portland blastfurnace cement.

US6709509B2 - Portland cement manufacture from slag

A process for the production of Portland cement and white Portland cement using magnesium furnace slag, a waste product from the manufacture of magnesium metal, as a primary starting material. The furnace slag is blended with calcium oxide and silicon dioxide to form a feedstock which is heated to a temperature and for an amount of time sufficient to form clinker.

SLAG CEMENT - COnnecting REpositories

The manufacture of slag cement is comparatively a simple process. The molten slag, after being granulated by passing into a stream of water, is first thoroughly dried, then pulverized between millstones, and finally sifted or bolted. Then about 25 per cent of slaked lime is added and thoroughly incorportted with the slag in an apparatus termed "homogenizer." This apparatus usually consists of ...

How Cement Is Made - Portland Cement Association

Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement. Bricklayer Joseph Aspdin of Leeds, England first made portland cement ...
