FINENESS TEST: FINENESS TEST The fineness of cement has an important bearing on the rate of hydration, rate of gain of strength, evolution of heat. Finer cement offers greater surface area. Disadvantage of fine grinding is that it is susceptible to air set & early deterioration. Maximum no. of particles in a sample of cement<100microns.
