Abstract
Granulated blast furnace slag powder activated by some alkalies presents high hydraulic activity and can be used as a high strength alkali-activated cement (AS cement). However, because of different hydration mechanisms, the strength characteristics of AS cement differ from those of portland cement. In this paper, the strength characteristics of AS mortar and/or concrete and factors effecting on the strength such as hydraulic activity of the slag, fineness of slag, types and dosages of activators, curing temperatures, compatibility to other admixtures, W/C, are presented.
