In the last years many studies have been addressed on the development of new types of cement with the aim to find a sustainable alternative to traditional ordinary Portland cement.Alkali-activated materials (AAM) seem particularly attractive for this purpose, even if effective admixtures such as plasticizers still need to be designed limiting so far the diffusion of AAM for geopolymer concrete preparation.AAM come from the alkali-activation of aluminosilicate powders with suitable amorphous content.Among all the suitable aluminosilicate precursors, great interest is nowadays focused on the possibility to activate industrial waste (e.g., slag or fly ash).The use of waste as precursors, along with a room temperature curing, makes these materials low-polluting binders potentially suitable for green building products.
