1 Overview With the high-speed development of urbanisation construction, the output of engineering waste slurry is increasing, which not only seriously pollutes the environment and wastes resources, but also exceeds the city's ability to dispose of engineering waste slurry and hinders the development of urban construction. According to the engineering waste slurry composition test weight of 70% ~ 80% is water, the rest is solid phase. Waste slurry in...
