STUDY ON MIX DESIGN AND DURABILITY FOR CONCRETE USING GRANULATED BLAST － FURNACE SLAG IN VARIOUS USAGE RATES AS THE MINERAL ADMIXTURES

Consideration for environmental load using blast furnace slag in concrete, we conducted various experiments. As results, even if a large amount of slag, satisfy the required performance fresh concrete and structures by conventional mix design. The durability is ensured wet curing period set from average temperature during expression compressive strength. Compared to ordinary Portland cement, carbon dioxide emissions at same strength are reduced 9 63%. This study expected increase spread environment-friendly concrete.
