(DOC) Effect of Blaine fineness of cement on rate of heat .

Increasing cement fineness increased the rate of heat generation. The primary problems in hot weather concreting related to the increased rate of cement hydration and evaporation of moisture from fresh concrete; which both increase the water demand. 2. Materials should be chosen that have been tested and performed well under similar conditions.
