Processing of Granulated Blast Furnace Slag and its

After the granulated blast furnace slag is formed, it must be dewatered, dried and ground, using processes similar to those used with Portland cement clinker to make Portland cement. Typically, granulated slag is ground to an airpermeability (blaine) fineness exceeding that of Portland cement to obtain increased hydraulic activity at early ages.

How Cement Is Made

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 rocklike substance that is ground into the fine powder that we commonly think of as cement.
