<p>PURPOSE:To prevent the aggregation of a high fineness cement liable to form dense and rigid flocs and to effectively draw the capability of a dispersing agent in a method for increasing the effect of the dispersing agent in the high fineness cement to increase the effect of the conventional dispersing agent in the high fineness (>=4000cm<2>/g in Blaine value) component. CONSTITUTION:This method comprises adding a larger excess amount of a pulverizing additive than the usual amount used to the high fineness cement at the time of pulverizing the cement clinker or before using the produced cement.</p> |
