Geopolymer composite and geopolymer matrix composition

摘要

A dry-mix composition for forming an ambient temperature cured, strain hardening geopolymer composite (SHGC) is disclosed. The dry-mix composition consists of (a) aluminosilicate material that is rich in silica and alumina in an amorphous form and (b) an alkali activator powder. Furthermore, the dry-mix composition is selected to (i) enable the ambient temperature cured SHGC to be formed without addition of liquid activator and (ii) exhibit strain hardening behavior accompanied by multiple cracking behaviour. Also disclosed is An ambient temperature cured, strain hardened geopolymer composite (SHGC) formed by adding water and a method of forming an ambient temperature cured SHGC.
