EARTH STABILIZATION METHOD Russian patent published in 2000 - IPC

FIELD: construction engineering. SUBSTANCE: method is used for stabilization of earth at erection of road bases. According to method, local earth is mixed with filler that is briquettes produced by pressing mixture of sludge obtained after chemical water purification at thermoelectric generation plants with 10-15% of cement and lime binding agent that is calcined mixture of carbonate sludge from thermoelectric generation plants with calcium chloride in amount of up to 2%, with subsequent compaction up to density of 0.95-0.98 of maximal value. Proportioning of local earth, briquettes, and lime binding agent can be like this 6:3:1-4:3:1. Application of aforesaid method allows for stabilizing earth together with utilizing sludge from thermoelectric generation plants according to simplified and cost-saving technology. EFFECT: higher efficiency. 1 cl, 1 ex
