GROUND MIXTURE Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: this ground mixture can be used in erection and reconstruction of bases for roads and airfields, for foundations of buildings and structures, creation of counterfiltration screens and cast-in-place piles. Ground mixture has stabilizing agent consisting of waste from processing of perchloroethylene, and binding agent. Ratio of components is as follows, mas.%: stabilizing agent, 0.003-15; water, 5-30; ground, the balance. Used in function of binding agent are hydraulic binders for example cement or binders of inorganic or organic origin and their amount is not over 10% of mass. Technological additives can be introduced into mixture such as screenings of rock materials, and/or salts of metals with valence not less than 3 and in amount not over 30% in mass. Application of aforesaid ground mixture allows for obtaining high strength and compacting capacity together with low water-permeability. EFFECT: higher efficiency. 7 cl, 2 tbl
