APPLICATION OF STEEL SLAG AS AN EFFECTIVE CONSTRUCTION ...

slag‟s have a very crystalline structure (due to the slow cooling conditions applied during processing and their chemical composition that lack SiO2), and hence, they only show weak cementations properties. In addition they can possess volumetric instability in presence of moisture. Coarse fraction (gravel-sizes) of steel slag is mainly used as road aggregates; however the problems related ...
