Alkali-activated aluminosilicates, is a relatively new material system that is currently the subject of considerable research and is beginning to see use as a binder in concrete. Of particular interest are newer versions of activated fly ash that are rapidly activated without any need for thermal conditioning or set enhancing additions beyond the basic activator. Set times can be regulated, the materials provide rapid strength development, and resistance to freezing and thawing is excellent due to their low porosity.
