Abstract:
The Japan Society of Civil Engineers (JSCE) studied the use of ground granulated blast furnace slag in concrete as an admixture. Various properties of fresh concrete and hardened concrete containing ground slag were examined. Ground slags included 13 samples on the market and 18 samples with different fineness and gypsum content especially prepared for the experiment from two kinds of water-granulated blast furnace slags. Based on the experimental results, the JSCE Standard "Ground Granulated Blast-Furnace Slag for Concrete" and the JSCE Recommendation "Recommendation for Design and Construction of Concrete Containing Ground Granulated Blast-Furnace Slag" were prepared and published in 1986 and 1988, respectively. This paper introduces the essential parts of both the JSCE Standard and the JSCE Recommendation, showing some of the representative experimental results.
