✦ Synopsis

Based on experimental data, this paper presents an empirical strength criterion for jet grouted soilcrete. Cylindrical specimens drilled from construction sites were tested to investigate the strength characteristics of soilcrete. Experiments conducted include the uniaxial compression test, Brazilian test and the triaxial compression test. It was found that soilcrete density increases with increasing depth. The uniaxial compressive strengths obtained were significantly greater than the design values suggested by the JSG Association of Japan. Experimental Poisson's ratios varied from 0.12 to 0.22, which are closer to that for concrete than that for native soil. Based on test results, a parabolic-type empirical criterion "cff=N'cyff+ To) M is proposed to describe the strength behaviour of soilcrete under low and tensile stress regions.
