Turk et al.  used a ﬁxed slump range of 185–205 mm in byproduct-based concretes that were designed using foundry sand or steel slag to partially replace the sand and FA as a mineral admixture, and they attempted to achieve comparable compressive strengths and water penetration. However,
The molten slag is rapidly chilled by quenching in water to form a glassy sand like granulated material. The disposal of such slag even as a waste fill is a problem and may cause serious environmental hazards with the projected economic growth and development in the steel industry, the amount of production is likely to increase many folds and ...
