DEODORIZING AND FORTIFYING BAD-SMELLING WATER-CONTAINING SOFT GROUND

PURPOSE:To deodorize bad-smelling water-containing soft ground efficiently and economically and fortify the ground, by dispersing an aqueous solution of divalent iron salt directly in the ground and adding specified two inorganic hardeners to it. CONSTITUTION:An aqueous solution of divalent iron salt is dispersed directly in bad-smelling water-containing soft ground and then additive A (gypsum dihydrate) and additive B (a mixture of 40-55wt% cement and 60-45wt% granulated blast furnace slagt with a particle size nearly the same as or smaller than that of cement) are added separately or simultaneously. A and B are used in the ratio of 10:90-30:70 by weight. The method deodorizes bad-smelling water-containing soft ground efficiently and economically and increases its strength.
