Oct 01, 2013  Generally, concrete develops strength through the formation of hydrates such as CSH (calcium silicate hydrate; 3CaO2SiO 2 3H 2 O), which is produced by the hydration reaction of water and the ordinary Portland cement typically used as a binder. Moreover, the hardening of fly ash-based geopolymer achieved by dissolving the Al and Si components of fly ash by alkaline activators is
