Specific Gravity of Cement | VDChari

Apr 01, 2019 · The specific gravity of OPC cement is taken as 3.15 means it is 3.15 times heavier than the water of the same volume. The specific gravity of cement is taken as 3.15, but this value will change over time if the cement is exposed to various weather conditions. Therefore, it is essential to determine the cement specific surface before using it.

Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
