    The effect of cement composition on cement strength has been studied extensively. 177,182,189,400,420 It appears that this effect is a rather complex one and depends on a variety of factors such as the mutual ratios of clinker minerals, the amount and form of added calcium sulfate and the presence of minor oxides. The available experimental data may be summarised as follows.Cement : Manufacture, Chemical Composition, Heat of ,2015-1-13 · cement, but is also influenced by water-cement ratio, fineness and curing temperature. As each one of these factors is increased, heat of hydration increases. For usual range of Portland cements, about one-half of the total heat is liberated between 1 and 3 days, about three-quarters in 7 days, and nearly 90 percent in 6 months.
