Compositions of clay suspensions for fixing moving sands and soils
Abstract
This article discusses the development of compositions of new, effective, water-soluble fixatives-reagents based on local raw materials and industrial waste. A technology has been developed for obtaining and using new types of complex additives-fixers based on hydrolyzed polyacrylonitrile polyelectrolyte, which can be recommended for implementation when fixing saline soils and sands of the Aral region. Chemical reagents and materials have been selected to create a structured crust and a three-dimensional structure in a system of moving sands and soils. The processes of creating compositions of clay suspensions for fixing moving soils and sands were studied, for which alkaline bentonites of the Krantau deposit and alkaline earth bentonite of the Beshtyubenskoye deposit were selected. As a result of the studies carried out, the features of the chemical fixation of moving sands using local raw materials were established to prevent salt and dust release into the environment and improve its environmental conditions.
