Title:
METHOD FOR INCREASING EFFECT OF DISPERSING AGENT IN HIGH FINENESS CEMENT
Document Type and Number:
Japanese Patent JP3280125
Kind Code:
B2
Abstract:
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 (≥4000cm2/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.
