Relation between working properties and structural properties from 27Al, 29Si and 31P NMR and XRD of acid-based geopolymers from 25 to 1000°C
Résumé
Highlights: (maximum 85 characters, including spaces, per bullet point). Acid-based geopolymers display different processing-dependent working properties. Acid-based geopolymers are mostly composed of Al-O-P and Si(OH)4 networks. The quantities of Al-O-P and unreacted metakaolin govern the thermal resistance. The increase of the Young's modulus is related to a higher thermal resistance. Ordered structures and low amounts of physisobed water lead to water resistance.
