The Investigation of Easy-Softening Alkali-Slag Wasteland Disposal by Building Artificial Mountain

The project used the Tanggu alkali-slag wasteland in Tianjin as a case-study of ecological restoration engineering project, researched the characteristic of alkali-slag and status of the unproductive land, manufactured the alkali slag soil to fill the low-lying-land, covered with exogenous planting soil and planted artificial vegetation which dominated by native plant which could survive easily, investigated the method of wasteland disposal by building artificial mountain of easy-softening alkali-slag.
