Foam concrete is widely concerned because of its excellent performance of heat insulation, fire prevention, sound absorption and low density.
Conventional foam concrete uses ordinary Portland cement (OPC) as the binder, but the energy consumption of cement production is high.
Each ton of cement emits about 0.
85 tons of CO ₂, accounting for nearly 8% of global anthropogenic CO ₂ emissions.
Geopolymer foam concrete (GFC) combines the lightweight and thermal insulation characteristics of foam concrete and the environmental protection and high-performance characteristics of alkali activated bonding system, and uses industrial by-products such as fly ash (FA) as the main binder to significantly reduce greenhouse gas emissions.
