Deep cement mixing (DCM) method has been successfully adopted in a lot of construction projects. In the DCM method, cement has been widely used as the binder. However, carbon dioxide CO2 emissions in the cement manufacturing process have become a considerable issue in recent years. Ground granulated blast-furnace slag (GGBS) is a candidate for the low carbon emission binders in the DCM method. This paper presents the direct tension test for investigating the tensile properties of the sand stabilized with the GGBS. The GGBS was used as the binder of the stabilized sand and the Portland cement (PC) was used as an activator for the GGBS. The specimens used for the tests were prepared in the laboratory. The specimens with the different ratio of the GGBS to PC were prepared for the direct tension test. The tensile stiffness and strength were evaluated from the tensile stress-strain curve. The unconfined compression tests were conducted using the specimens prepared by the same method to investigate the relationship between the tensile and the compressive strengths.
