Experimental studies of physical and mechanical properties of soil-cement based on homogeneous sands of one fraction

Abstract

The article considers the technology of jet cementation of soils as a method of reconstruction of port hydraulic structures, substantiates the relevance of its application. An overview of the Jet Grouting technology and the history of its development is given. Examples of the application of the technology of jet cementation of soils in hydraulic engineering construction are considered. The analysis of the dependencies of density, uniaxial compressive strength and deformation modulus of soil-cement manufactured in laboratory conditions is carried out. In the course of the analysis, the authors proposed a new concept of "Pore filling coefficient" and described the effect of this coefficient on the characteristics of soil-cement. Based on the results of the analysis, conclusions were drawn and recommendations for further research were given.
