Abstract:

There are more and more reports of construction on municipal solid waste landfills. But there are no systematic experiences and perfect design method for improvement of municipal solid waste. According to statistical results from national municipal solid waste landfills, artificial municipal solid waste was made. The unconfined compressions of artificial municipal solid waste were tested in under-degradation or in-degradation or past-degradation, mixed with cement 25 %, 35 %, 45 % at different maintenance periods. It is obtained that hardening stress strain curves and the strength law of artificial municipal solid waste mixed with cement versus maintenance period and cement content as well as degradation phase. The test results show that the organic constitute in artificial municipal solid waste can reinforce and weaken the artificial municipal solid waste mixed with cement. There are different strength characteristics of artificial municipal solid waste mixed with cement at different degradation phases. Only municipal solid waste at past-degradation can be better improved. It is suggested that the cement content is more than 35 %.

Key words: unconfined compression test, artificial municipal solid waste, cement, degradation phase, maintenance period
