Стабилизация песчаных грунтов инъекцией синтетических смол

Abstract

It is presented results of laboratory tests of sandy soils stabilized with polymer resins. Comparison was done of properties of no modified carbamide resins with properties of modified carbamide resins. Such properties of solution of resins have been investigated: density, viscosity, pH (alkalinity level), evaporation of components from solution. During the investigations properties of alluvial medium dense sand stabilized with no modified and modified resins have been compared. Such properties of reinforced soil have been investigated: uniaxial strength, evaporation of components of resin from soil, time dependent strength of soil. Addition of active components increases density and pH of solution of carbamide resin, decrease viscosity. Uniaxial strength of sands stabilized with polymer resins is time dependent and increased from 2,2 MPa after 7 days to 2,9 MPa after 2 months.
