Stress-Strain Behavior of Cement-Improved Clays

Quiroga, Allison J. / Muraleetharan, Kanthasamy K. / Cerato, Amy B. / Miller, Gerald A.

Chemical improvement techniques are used to increase strength and decrease deformability of soils. Addition of cement slurry changes the engineering properties of soft clays. In this paper, laboratory test results of an unimproved soft clay are compared with those of cement-improved samples. Laboratory testing of these specimens included one-dimensional consolidation testing and undrained triaxial compression, extension, and cyclic loading tests. Results of the laboratory testing show a change in the stress-strain behavior of the material due to the influence of the cementitious bonds formed during the improvement process. An indication of the strength of these bonds was estimated by determining an “apparent pre-consolidation pressure,” via the Casagrande method from the one-dimensional consolidation test results, and an artificial stress history was observed. Due to the range of triaxial confining stresses used in this study, all of the laboratory-improved soil triaxial test results exhibited behavior similar to those of heavily overconsolidated clays including high initial strength and dilation behavior.
