Shrinkage Properties of Cement Solidified Sludge with High Water Content

Abstract:

Article Preview

Solidified sludge as backfill material exists serious phenomenon of shrinkage and cracking, and the project's strength, permeability and stability will be adversely affected. The material used in this study is sludge with high water content from the Metro construction sites in Hangzhou. In this paper, our main research is the influences of the initial water content of sludge, curing period and cement content on the curing shrinkage of silt. The results show that the shrinkage increases with initial moisture content, decreases with the increase of the cement content, and increases with curing period. Strength decreases with the increase of initial water content, increases with cement content, and increases with curing period. The test has a certain reference value to the engineering practice.
