Antiseepage elements of plastic and hardening materials made on the base of local low-grade clays
Analyzed were the possibilities of complex use of polymineral clays in compositions of tixotropic solutions and ASM. Justified was the necessity to develop normative documents including the technology for solutions preparing, methods to increase solutions quality (chemical additives, dispergation and so on), development of criteria to determine clays good for solutions. There are given the examples of the objects where the tixotropic solutions and ASM, based on low-grade polymineral clays, were used.
