Hello Pankajbits, All other factors being equal, low free lime clinker (hard burned) is generally harder to grind than clinker with higher free lime. This is due to physical changes in clinker mineralogy and porosity caused by over-burning rather than the presence of the free lime itself.

Portland cement’s chemistry comes to life in the presence of water. Cement and water form a paste that surrounds and binds each particle of sand and stone. Through a chemical reaction of cement and water called hydration, the paste hardens and gains strength. The character of concrete is determined by the quality of the paste.
