Abstract

The replacement of new binders with traditional ones such as lime and cement has caught the eye of researchers in recent decades. The majority of researchers rely on the use of environmentally friendly binders that produce less carbon footprint in the production process. Geopolymer, and more generally, Alkali-Activated Materials (AAMs) are among these binders which can potentially offer an efficient alternative to traditional binders. On the other hand, waste storage generated from quarry and mining industry such as coal gangue has a high risk of environmental pollution. Since most of them contain a lot of silica and alumina, they can be a promising alternative/substance as a precursor in AAMs generation. This paper, thus, reviews the literature on using industrial wastes such as coal gangue and waste glass as precursors for producing AAMs.
