Cement Kilns: Special Clinkers

Low Heat Clinkers. In the late 1920s, the elucidation of the phases in clinker was paralleled by research into the heat evolved when cement hydrates. It was found that most of the heat evolved is produced by the hydration of tricalcium aluminate, and to a lesser extent, alite. At about this time, a number of big concrete dams were being
