Of over 20 million tons of mixed construction and demolition waste generated annually, only 5% is recycled and less than 1% is adopted for low-grade construction activities. This innovative research aims to solve Australia’s mixed construction and demolition waste disposal problem and lower its greenhouse-gas emissions at the same time. The research develops Het-Gregate with novel chemical admixtures and greenhouse-gas emissions to create Het-Crete, with new mixing techniques for its an optimal performance high-grade concrete. Life-cycle analyses will be conducted to generate Het-Crete specifications for the industry. This will significantly elevate Australia’s world standing in recycled concrete research.

在每年产生的超过2000万吨的混合建筑和拆卸废物中，只有5%被回收，而用于低级建筑活动的不到1%。这项创新研究旨在解决澳大利亚建筑和拆除废物混合处理的问题，同时降低温室气体排放。该研究开发了Het-Gregate，采用新型化学外加剂和温室气体排放来制造Het-Crete，并采用新的混合技术来实现其最佳性能的高等级混凝土。将进行生命周期分析，以生成该行业的Het-Crete规格。这将大大提升澳大利亚在再生混凝土研究领域的世界地位。
