Relation Between Fine Grinding Of Cement And Setting

2020-8-16The required fineness of good cement is achieved through grinding the clinker in the last step of cement production process. As hydration rate of cement is directly related to the cement particle size, fineness of cement is very important. Importance of Cement Fineness. The fineness of cement affects hydration rate, and in turn, the strength.

    Finer cement offers a greater surface area for hydration and hence faster the development of strength. The disadvantages of fine grinding is that it is susceptible to air set and early deterioration. Maximum number of particles in a sample of cement should be about 100 microns-1.5 microns while average size is about 10 micron.
