Investigation of Geopolymer based Concretes for the Construction of High Fire Risk Infrastructures

地聚合物混凝土是一种新兴的新材料，有望获得优异的耐火性和耐久性，而且可能比广泛使用的高强度混凝土便宜，后者也消耗大量的波特兰水泥。生产1吨波特兰水泥会释放1吨温室气体。此外，澳大利亚目前生产的650万吨/年水泥不足以满足行业需求。该项目调查了在不使用任何波特兰水泥的情况下使用飞灰制造大地聚合物混凝土的情况，以找到澳大利亚燃煤电厂每年产生的1100万吨飞灰的一部分用途。

Geopolymer concretes are emerging new materials promising superior fire resistance and durability and potentially cheaper than the widely used high strength concretes, which also consume high levels of Portland cements. Production of 1 ton of Portland cement releases 1 ton of green house gases. Further, the 6.5 million tons/year of cement currently produced in Australia is insufficient to meet the industry demand. This project investigates the use of fly ash to make geopolymer concrete, without using any Portland cement, to find usage for part of the 11 million tons/year of fly ash produced as a waste from coal power stations in Australia.
