The Indian Cement Industry is the largest consumer of fly ash consuming about 28% of the total fly ash generated in the Country. 5 Electrical energy demand also depends on the product characteristics. Higher the requirement for a cement's strength development, finer it needs to be grinded, requiring significantly more energy in the grinding ...

In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section 25.3.2). It is estimated that this may reduce the carbon footprint of the cement industry by 3–5%.
