Experiment research on the mechanics properties of urban garbage blocks

摘要

A municipal solid waste treatment method named stacking landfill of garbage block is brought forward. Garbage blocks were made and a series of tests have been carried out by orthogonal tests method in lab. Test results indicate the early compressive strength of garbage blocks increases quickly, and more slowly in the later period. The compressive strength for 3 days curing age is about 40% ～ 45%s of that for 28 days curing age. The compressive strength for 5 days curing age is about 50% ～ 60% of that for 28 days curing age. The compressive strength for 7 days curing age is about 60%～70% of that for 28 days curing age. The rank of the influence degree of the accession material to the compressive strength for 5 days curing age was are the mass of cement, the mass of waste type, compressive stress size, the mass of water, the mass of lime. Stacking landfill of garbage blocks differs from traditional landfill disposal which is a new type of classifier ecological landfill method. It can effectively reduce the volume of urban waste, and the waste can easily be stored and disposed.
