Abstract:In the project of the comprehensive treatment of sewage system in the urban center of Yueyang City, by adding cement-based materials of solidification to solidify in laboratory simulations, this paper studies the various index parameters of the silt after the treatment. It shows that the silt can be used as the material for filling up subgrades after the cement-based treatment of solidification. Meanwhile, applying to the actual situation, the design and method of construction for solidifying the resource of sludge used to fill up subgrades are put forward, so as to solve the problem concerning the utilization of the resource in projects of dredging sludge.
