Quality of coal for Indian Cement Industry
Coal is the main fuel for the manufacture of cement in India, given the high cost and inadequate availability of oil and gas. The consumption of coal in dry process system ranges from 20-25per cent of clinker production. That means 0.20-0.25 T of coal is consumed to produce one tonne of clinker. The cement industry consumes about ten …

Laying the foundation for zero-carbon cement
Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to high …
