What is Ground Granulated Blast Furnace Slag (GGBS)? The ground granulated blast furnace slag (GGBS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength, and durability.. This material is obtained by the heating of the iron ore, limestone, and coke at a temperature of about 1500 o C. The process is carried out in a blast furnace.

Slag Cement - Lehigh Hanson, Inc.

Slag cement requires nearly 90% less energy to produce than portland cement. According to the Slag Cement Association, substituting 50% slag cement for portland cement reduces greenhouse gas emissions by more than 40% and lowers the embodied energy of concrete by more than 30%. Another factor is slag cement’s nearly white color.

Hydration products of alkali activated slag

01-04-1995  From Figs 7-10 it can be seen that the rims become clearer and thicker with ageing. Similar rims have been observed around slag particles hydrating in Portland cement/slag blends (26). The presence of the rims suggests that the slag particles may form some in-situ products by a solid state mechanism at later ages.
