2020-3-25 · This limits the increase in specific surface area, and can result in coating of the mill internals, which causes a reduction in the rate of breakage. Grinding additives contain surfactant chemicals, which absorb on the surface of the cement grains, neutralise the surface charges and shield against the inter-particle attractive forces.

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.

1. The influence of specific surface area, particle gradation and particle shape of cement. Relevant research shows that if the cement specific surface area is 300~400m2/kg, if the particle size distribution slope n of the cement and the clinker reactivity are unchanged, the water content of the standard consistency will increase by 100m2/kg. 6%.
