Development and application of recycling CLSM with using a large amount of industrial wastes

本课题研究的是安全利用大量工业废渣的CLSM再生技术的开发与应用。首先，利用日本城市生活垃圾制成的一种特殊类型的水泥和骨料，对一种新开发的受控低强度材料(CLSM)的物理性能和渗滤液特性进行了评价。生态水泥在日本被称为生态水泥，是一种最新的绿色水泥，主要由城市垃圾焚烧灰和城市污泥制成。本文使用的骨料也是由生活垃圾焚烧炉的炉渣制成的。还使用了大掺量超标飞灰。试验结果表明，这种新型的绿色CLSM具有足够的强度发展和合理的流动性，特别是当混合料的比例经过精心设计时，将是一种很有前途的可持续减排材料。本文对这种新型CLSM的渗滤液特性进行了评价。两种类型的标准测试显示出可接受的渗滤液水平。根据这些测试结果，证实了广泛的城市固体废物可能适用于新的绿色CLSM的材料。

This project investigates the development and application of recycling CLSM with using a large amount of industrial wastes safely. First of all, the physical properties and leachate characteristics of a newly developed CLSM (Controlled Low Strength Materials) were evaluated with a special type of cement as well as aggregate made from municipal solid waste in Japan. Eco-Cement, so-called in Japan, is the latest green cement made primarily from municipal refuse incineration ash and sewage sludge. Aggregate used in this paper was also made from the slag of municipal solid waste incinerator. High-volume off-specification fly ash was also used. This new type of green CLSM will be a promising sustainable material to reduce CO2 emissions.The peoject results showed and adequate strength development and reasonable flowability, especially when the mixture proportion is carefully designed. The leachate characteristics of this new CLSM are evaluated in this paper. Two types of standard tests showed acceptable leachate levels. From these tests results it was confirmed that a wide range of municipal solid waste may be applicable for the materials of the new green CLSM.
