Geopolymer cement - Wikipedia

Production. Production of geopolymer cement requires an aluminosilie precursor material such as metakaolin or fly ash, a user-friendly alkaline reagent (for example, sodium or potassium soluble silies with a molar ratio MR SiO 2:M 2 O ≥ 1.65, M being Na or K) and water (See the definition for "user-friendly" reagent below). Room temperature hardening is more readily achieved with the

What is calcium-aluminate cement?

The cements of higher alumina content are suitable for higher-temperature appliions. Calcium-aluminate cements are primarily used for high heat refractory appliions. Other uses include moderate acid-resistant appliions, high-early-strength and quick-setting mixtures, and as part of the expansive component in some shrinkage-compensating
