Abstract

This paper presents the development of the unconfined compressive (qu) and the splitting tensile strength (qt) of a chemically stabilized silt soil. For this, specimens with a volume of 196,35 cm3 were prepared using cement contents of 3%, 5%, 7% and 9% and then tested after 7 days of cure. The porosity/volumetric cement content (η/Civ) was used as the main parameter of the results analysis. The results show that with the decrease in the ratio η/Civ the values of qu and qt increase. Thus, the decrease in porosity meant an increase in qu and qt. A general estimation equation for qu and qt was developed to estimate the resistance of the mixtures with the use of η/Civ adjusted to a scalar equal to 0,45. The equations showed that it is possible to estimate the value of qu and qt of treated soil among the amounts of cement, η/Civ ratio and curing time employed in the present work. Finally, a constant ratio of qt/qu=0,15, which is independent of the voids and the volumetric content of cement, was calculated.
