Effect of Micro-Grinding Medium on the Particle Size Distribution and Properties of Portland Cement

Abstract:

The effect of micro-grinding medium on grinding performance of Portland cement, with determining specific surface area, 45um and 80um sieve residue, density, particle size distribution, chemical shrinkage and strength were studied. In this article, the RRBS of grinding of cement particle size distribution data was observed to be very well. When the content of micro-grinding medium is less than 10%, the specific surface area is increased as the ratio of the grinding medium increased. At the same time, the flexural and compressive strength of cement increased as the content increases. The density of cement decreased quite significantly with the content of micro-grinding medium increased. The 80um sieve residue of the cement increases obviously, when the content of micro-grinding medium is more than 10%.
