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

本项目探讨了利用大量工业废弃物安全回收CLSM的开发与应用。首先，用一种特殊类型的水泥和由日本城市生活垃圾制成的骨料对新开发的CLSM（受控低强度材料）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污水污泥制成。本文所使用的骨料也是由城市生活垃圾焚烧炉的炉渣制成的。还使用了大量不合规格的粉煤灰。这种新型的绿色CLSM将是一种有前途的可持续材料，可以减少二氧化碳的排放。工程结果表明，其强度发展充分，流动性合理，特别是配合比设计合理。本文对这种新型CLSM的渗滤液特性进行了评价。两种标准测试显示渗滤液水平是可接受的。从这些试验结果证实，广泛的城市生活垃圾可能适用于新型绿色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.
