Study for Engineering Utilization of Slag Soil in Tianjin Alkaline Factory

Large amount of dregs has been generated during the manufacturing of pure alkali in Tianjin Alkali Works. The urban environment is seriously affected by this material. So studies on the behavior and the utilization of the alkali residues and its influence on the environment were conducted by using simulated tests in laboratory and field as technical measures. Meanwhile, the influences on environment are evaluated through specific projects. This research shows that alkali residue may be used as soil of engineer. Not only to be used in large scale for filling low land areas and beach zones in Tanggu, but also to be used to improve the ecological environment. This utilization would solve the problem associated with the storage of alkali residue. It also has remarkable social, economic, and environmental benefits.
