The typical cost of production of clinker in a large cement plant in India stands between 1,100 and 1,600 Indian Ruppes per tonne. While at most locations, fly ash is available at a cost of 300 to 800 Indian Rupees per tonne, including transportation to the cement plants, at
Clinker is a nodular material which is produced in the kilning stage during the production of cement. It is used as a binder in many cement products. Clinker nodules are around 3-25 mm in diameter and dark grey in colour. Limestone and clay is heated to about 1400oC-1500oC in the rotary kiln to produce clinker.
The second major component in the production of cement is the cost of raw materials. The primary raw material that's used is limestone. Raw materials account for 30%–40% of the cost of sales.
Cost-Effectiveness: Its availability and performance make it a cost-effective choice for large-scale projects. Types of OPC. There are several grades of Ordinary Portland Cement, each designed for specific applications: Grade 33: Suitable for standard quality works. Grade 43: Ideal for higher strength concrete applications.

A crude estimate of the shipping cost of cement is $18 in 2011 dollars (Van Oss, 2004, p. 16.5).7 ... 2 and 1 million metric tons per year of clinker costs C130 and C170 per metric ton in 2007 Euros. Assuming a linear relation between the production ...
production costs and increased demand have contributed to rising cement prices. Low-Carbon Cement The chemical reaction inherent in cement making— calcination to produce clinker—accounts for about 60% of the industry's carbon emissions. The remainder comes from direct and indirect processes (e.g., fossil-fuel combustion and energy use).
The oxyfuel technology has the lowest cost of clinker, 93 €/t clk, and the membrane-assisted CO 2 liquefaction has the highest cost of clinker of 120 €/t clk. Overall, the cost of clinker is shown to increase with 49–92% …
