Sustainable Concrete Materials

2021-9-16  fly ash and amorphous silica. Fly ash and amorphous silica are pozzolanic materials that harden by reacting with the calcium hydroxide released during the hydration of portland cement. Slag has latent hydraulicity, ie in the presence of alkaline materials such as portland cement, it will react with water to form hardened binder.
