Development of an Alkali Activated Slag based Construction Material for High Fire Risk Infrastructures

该项目将开发一种用于隧道施工的碱矿渣（AAS）基建筑材料。 在隧道中，传统的混凝土很可能在碳氢化合物火灾事故中“剥落”，可能导致隧道坍塌。 该项目将开发一种抗剥落的AAS，作为传统波特兰水泥的替代品，波特兰水泥每年在澳大利亚造成650万吨温室气体排放，而AAS是基于矿渣，一种工业废物。 该项目还旨在更好地了解剥落现象，以便工程师能够有信心地设计传统混凝土隧道的防火措施。

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.
