It is estimated that there is 75% capacity utilization in this industry which means the annual industry volume is 180 MT per year. The industry is growing at 8% CAGR every year.
The sale price per bag of cement ( 1 Bag = 50 KG) is Rs.250 which makes the total industry size at today prices a whopping Rs. 90,000 Crores or USD 18 Billion! The top four companies, ACC, Ambuja Cement, Grasim and UltraTech (L&T) account for nearly 40% of this industry.

Incidentally, The history of Portland Cement dates back to the time when it was found that by burning limestone containing clay and silica, a cementing agent was produced which hardened under water and after hardening was not soluble in water. This end product somewhat resembled the commonly available Portland stone in colour and character, hence it was named Portland Cement.
Limestone, Coal and Transportation costs are the major cost components in the manufacturing of cement.
