Levenko H. Fixing soil bases contaminated with peracetic acid

Object - deformation of ground foundation of foundations under the influence of solutions of peracetic acid; the purpose is to study the changes in the physical and mechanical properties of soil bases contaminated with peracetic acid, and to develop a method of their fixation; novelty - the general scheme of the reaction of formation of silicate-peracute gels was established and the most effective ratios of components of one-soluble, two-component technology of fastening of soil bases contaminated with peracetic acid were recommended; the model of behavior of the soil base contaminated with peracetic acid in the conditions of reconstruction is proposed; the calculation of parameters of chemical fixation of soil bases of foundations contaminated with peracetic acid has been improved; Physical and mechanical properties of acidified soils fixed with silicate-peruxeous solutions are investigated; results - the quality of chemical fixation of soils contaminated with acid industrial wastewater has been raised, in case of application of recommended formulations, the ecological state of contaminated soils of soils has been improved by cleaning them from the pollutant, a model of the soil substrate contaminated with peracetic acid has been developed, the formulations of working fixing solutions have been developed, allowing to provide dirt to the contaminated array of grenades strength, which is close to natural values and durability; industry - construction. Methods - experimental methods for studying the influence of solutions of peracetic acid on the properties of ground soils; standard methods for determining the physical and mechanical properties of soils; mathematical modeling of the stress - strain state of the "base - foundation" system using the finite element method (FEM).
