concrete. GGBS slag is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. In this project it is proposed to study the Experimental Behavior of Reinforced Concrete with Partial Replacement of Cement with GGBS.

leaching; concrete manufacturing 1. Introduction Blast furnace slag (BFS) is a non-metallic industrial by-product, which is produced in blast furnaces by the melting of the iron ore, producing molten pig iron [1]. Worldwide, more than 500 million tons of blast furnace slag are produced every year [2]. The blast furnace slag can be granulated slag (GBFS) or air-cooled blast furnace slag (ACBFS ...
