It is about 2550 (normally about 40 percent) of cement. it renders the clinker easier to grind, increases resistance to freezing and thawing, hydrates rapidly generating high heat and develops early hardness and strength. however, raising of c3s content beyond the specified limits increases the heat of hydration and solubility of cement in water.
Cement making, and many other purposes. in commercial operations, the price of coal not only reflects the quantity of coal but also reflects the relationship of a desirable property or a combination of properties to performance of the coal under service conditions.
