| Research Abstract |
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.
