SLURRY COMPOSITIONS FOR GROUND IMPROVEMENT USING BLAST-FURNACE SLAG CEMENT AND METHOD OF PRODUCING SOIL CEMENT SLURRY BY USING SAME

摘要

Slurry composition for ground improvement is obtained from cement, water and an admixture. The slurry composition cement is of a kind prepared by using blast-furnace slag cement of a specified type as the cement at a water/blast-furnace slag cement mass ratio of 40-250% and contains the admixture in an amount of 0.1-5 mass parts for 100 mass parts of the blast-furnace slag cement. The blast-furnace slag cement of the specified type contains blast-furnace slag fine particles with fineness 3000-13000 cm²/g in an amount of 60-80 mass % and portland cement in an amount of 20-40 mass % for a total of 100 mass %.
