Description

Geopolymer composite panels can be produced using Australian geopolymer concrete technologies such as Zeobond E?Crete, which use fly ash and slag to reduce embodied CO2 by around 80% compared to OPC. E?Crete is specified using standard concrete strength grades (e.g., 20?50 MPa), indicating typical compressive performance for geopolymer panels and precast products.

Geopolymer technology was developed in the 1970s by Joseph Davidovits. Australian commercial application began in 2013 with Wagners Earth Friendly Concrete at Brisbane West Wellcamp Airport. Zeobond (Melbourne) pioneered E-Crete technology. Current applications focus on infrastructure and structural elements rather than thin panels. Port Kembla breakwater (2023) and various Queensland Transport projects demonstrate marine durability. Thin panel applications (15-25mm) remain in development phase requiring custom manufacturing through established producers.
