Description
Geopolymer/alkali-activated concrete uses industrial by-products such as fly ash and slag activated with alkaline solutions to form a cementitious binder. In Australia, products such as Zeobond E-Crete and UniqueCem LCC are used as lower-carbon alternatives to OPC in slabs, panels, and precast elements.
Primary Sectors
[Transport & Infrastructure][Industrial]
Typical Uses
- Structural floor slabs and suspended slabs
- Precast wall panels and facade elements
- Marine structures and coastal infrastructure
- Industrial floors requiring chemical resistance
- Infrastructure projects (bridges, tunnels)
- Fire-rated separating walls and floors
- Thermal mass walls for passive design
