Researchers A/Prof JG Sanjayan

Brief description This project will develop an alkali-activated slag (AAS) based construction material for tunnel construction. In tunnels, conventional concretes are likely to ?spall? in a hydrocarbon fire accident, possibly resulting in a tunnel collapse. The project is set to develop a spalling-resistant AAS as an alternative to conventional Portland cement, which is responsible for 6.5 million tons of greenhouse gas emissions in Australia per year, whereas AAS is based on slag, an industrial waste product. The project also seeks to provide better understanding of the spalling phenomenon so that the engineers can design fireproofing for conventional concrete tunnels with confidence.
