Reaction mechanisms and kinetics in geopolymers incorporating strontium salts

Year: 2025

Type: article

Abstract: Strontium salts reduce the rate and extent of reaction of geopolymers due to (1) reduced metakaolin dissolution due to lower pH and sorption of Sr 2+ to metakaolin surfaces, and (2) a ‘filler effect’ arising from insoluble strontium salt particles.
