AGGREGATE FOR HYDRAULIC CEMENT COMPOSITION AND HYDRAULIC CEMENT COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide aggregate for a hydraulic cement composition which practically uses blast furnace granulated slag or its particle size adjusted material and in which the blast furnace granulated slag is made to hardly agglomerate over a long period and to have water retention characteristics, so as to be suitable for preparing the hydraulic cement composition using it as the aggregate and to suppress the bleeding of the prepared hydraulic cement composition, and to provide the hydraulic cement composition. SOLUTION: The aggregate for the hydraulic cement composition obtained by mixing 0.002-0.3 pt.wt. water insoluble and high water absorptive acrylic cross-linked polymer having≥60 mol% in total of a structural unit formed from acrylic acid and a structural unit formed from acrylic salt in the total structural unit with 100 pts.wt. blast furnace granulated slag or its particle size adjusted material is used.
