BLAST FURNACE SLAG FINE POWDER CONTAINING INORGANIC ADMIXTURE, BLAST FURNACE CEMENT, AND METHOD OF PRODUCING THEM

摘要

PROBLEM TO BE SOLVED: To improve the initial strength of blast furnace slag fine powder and blast furnace cement by incorporating an inorganic admixture therein. SOLUTION: As the inorganic admixture, mineral fine powder having a mean grain diameter of =10 m is added by 2.5 to 12.5 mass%. The mineral fine powder suitably consists of at least one or more kinds selected from lime, dolomite, silica, band shale, bauxite and annealed blast furnace slag having a glass forming ratio of =70%.
