Het-Crete: High-Grade Chemical-Treated Heterogeneous Recycled Concrete

在每年产生的2000多万吨混合拆建废物中，只有5%被回收利用，不到1%被用于低等级建筑活动。这项创新研究旨在解决澳大利亚建筑垃圾和拆迁垃圾混合处理的问题，同时降低其温室气体排放。这项研究开发了Het-Gregate，使用新型化学外加剂和温室气体排放来创建Het-Crete，并采用新的搅拌技术来实现其最佳性能的高标号混凝土。将进行生命周期分析，以生成该行业的Het-Crete规格。这将显著提升澳大利亚在再生混凝土研究领域的世界地位。

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.
