In the present study, small grinding media particles (1/2") were incapable of fracturing the large particles of the sample, hence the average particle size limited the continuous decrease in size. Therefore, the decision was made to submit Portland cement CPC40 to a longer grinding process (8h and 10h).
TYPES OF PORTLAND CEMENT Portland cement is a closely controlled chemical combination of calcium, silicon, aluminum, iron and small amounts of other compounds, to which gypsum is added in the final grinding process to regulate the setting time of the concrete. Some of the raw materials used to manufacture cement are limestone, shells, and chalk or
