Tensile properties of cement-treated clay

This paper presents the direct tension test results providing the tensile properties of cement-treated clays. The direct tension test was conducted for the cement-treated clay specimens prepared with several cement contents in a laboratory. The local displacement transducers were used to measure the deformation of the specimen accurately. The unconfined compression test was also conducted for the specimens prepared in the same manner as the tension test specimens. The direct tension test results shown that the stress-strain relationship of the cement-treated clays is nearly liner under the tensile loading. The tensile strain is around 0.05% at the peak tensile stress. The tensile strength increases with the cement contents. The ratio of the tensile strength to the unconfined compressive strength is around 0.2. This ratio is the same as that for the cement-treated sands.
