Abstract:Cement stabilization is one of the most widely used soft ground improvement methods, with Portland cement being the most commonly employed binder. However, there are significant environmental impacts associated with the production of PC in terms of high energy and no-renewable resources consumption as well as CO2 emissions. In order to mitigate this effect, the incorporation of industrial by-products in partial or full cement replacement as soft soil stabilization has been encouraged. The production process, chemical properties, application and soft soil stabilization mechanism of an industry by-product/waste-ground granulated blastfurnace slag (GGBS) are introduced. The utilization of GGBS in stahilization of soft soils stabilization can reduce the significant environmental impacts associated with Portland cement production and increase the soft soil stabilizing efficiency and reduce the engineering cost.
