A recent study published in a peer-reviewed journal has found that ambient-cured lightweight geopolymer concrete retains its structural integrity under high temperatures, making it a promising material for fire-resistant construction. The research, conducted by scientists at an undisclosed university, tested the concrete's compressive strength after exposure to temperatures up to 800Β°C.
The study reports that the geopolymer concrete, made from industrial byproducts like fly ash and slag, maintained over 70% of its original strength after heating, outperforming traditional Portland cement concrete, which often spalls and loses strength under similar conditions. The material's lightweight nature also reduces structural load, offering additional benefits for building design.
Experts note that while the results are promising, the paper is still awaiting final editing and should not be considered conclusive. Further research is needed to assess long-term durability and scalability for commercial use. The findings could impact the construction industry by providing a safer, more sustainable alternative to conventional concrete.
