Production and Use of Blast Furnace Slag Aggregate for Concrete
It has been more than 30 years since the use of blast furnace slag as concrete aggregate was included in JIS; however, it is not very popular today, and the annual sale of slag for aggregate use of Nippon Steel & Sumitomo Metal Corporation stays at the level of one million tons. With the latest trend toward a recycling oriented society, however, effective use of slag is attracting …

Blast Furnace Slag
Air-cooled blast furnace slag has been extensively used as a construction aggregate. 5.3.2 Granulating. Although the history of the use of blast furnace slag can be dated back to as early as 350 BC, it had been basically used as an aggregate material, until the hydraulicity of granulated blast furnace slag was found. Now, granulation is ...
