The effects of grinding on the properties of Portland ...

2013-11-1  It is shown that the grinding quality greatly controls the properties of Portland-limestone cement. • It is especially the fineness of Portland clinker that is important because the limestone (more soft) is always finer. • Crushed limestone (fillers) behaves like crushed Portland clinker for the powder packing density and the pastes consistency. •

The influence of grinding on the limestone properties

Another method was grinding of different weights of the same sample. The last one used the same weight of different samples. In the ball mill, sample of one type of limestone was ground for various milling time. The particle size, shape of particles, phase composition and crystallite size were studied for
