Improving Construction Engineering Properties of Soils Stabilized by a Cement Binder with Techno-Genic Products

The article considers the method of stabilizing roadbed soils by introducing metallurgical waste in the structure of the composite binder. It was established during the analysis and experimental research that construction engineering properties are improved as a result of the method. The article provides the obtained results of laboratory tests. The optimum amount of ground blast furnace slag as a component to replace part of Portland cement in a soil cement mix is determined. The dependence of strength gain on the hardening time at different proportions of the composite binder is given. The efficiency of the considered method of soil hardening is estimated.
