SOIL STABILIZATION BY MEANS OF »LENDUR EH« UREAFORMALDEHYDE RESIN

Abstract

Geomechanical behaviour of soil is determined by its physical and chemical properties. Sometimes geomechanical properties do not meet conditions required and improvements are necessary. Improvements can be made applying various soil stabilization methods depending on required conditions, type and properties of soil, and the material used for stabilization. Polymers can also be used for stabilization. In some cases ureaformaldehyde resins are used. The properties of a soil sample and ureaformaldehyde resin were determined. Several samples of soil and resin mixed in different ratios were prepared. Investigations of different parameters show that the resin significantly improves geomechanical soil properties. As a result the ureaformaldehyde resin applied in the tests can used for stabilization.
