2017-2-1  1. Introduction. Ground granulated blast-furnace slag is an amorphous by-product of iron industry. Research has shown that blast-furnace slag can be alkaline activated to potentially substitute the ordinary Portland cement (OPC) as an alternative binder in concrete , .Alkali activation of slag is the process of promoting the dissolution of aluminosilicate vitreous structures in slag in a high ...

2018-7-27  Intense water consumption and energy for drying can be avoided by dry dispersion and quick air cooling of the liquid slag. The essential point for any dry technique is that the obtained slag product meets the properties as cement additive. Basically the target is to achieve at least the quality of wet granulated slag sand.
