Geopolymer concrete and method of preparation and casting

摘要

A method of forming a geopolymer moulded product comprising: forming a geopolymer concrete composition comprising an alkali or alkaline earth metal silicate component, an alkali or alkaline earth metal hydroxide, aggregate and water wherein the water content is insufficient to provide a slumped concrete and the ratio of SiO₂ to M₂O is at least 0.8; and casting the concrete into a mold and subjecting the moulded concrete to consolidation in the mold.
