STUDY OF HORIZONTAL SCREEN STRENGTH CREATED BY INJECTION TECHNOLOGY CEMENT BINDER BASED

An important indicator in the planning of injection works is a particle size distribution of the soil and the very composition of injection. The ideal case is to comply with the injection optimum ratio between the size of particles in solution and injectable medium. This ratio corresponds to complete impregnation of the environment. Today in the field of building technologies known classical methods of grouting with the injection process [9]. This may be a cementation or silicification with different chemical compositions. Due to the fact that we have proposed an innovative technology of impervious curtain device, special attention should be paid to the performance and physical and mechanical properties of the resulting soil-injection. This is due to the fact that the proposed technology provides for lesser known technical solutions, the use of which should ultimately result in impervious screens with desired properties. Goal. The aim of this study is to investigate the properties of the resulting soil-concrete impervious screen. Such structures should have defined a number of physical and mechanical properties. In this paper, it was of interest to study the compressive strength of the resulting soil-concrete structure. Conclusion. As a result of experimentation and implementation of complex obtained experimentally-statistical models that describe the main soil-quality indicators. Based on these data is possible optimal selection of formulation and technological structure for sandy soils with different modules size of its particles.
