Abstract

Since there are plenty soils in the nature that sodium chloride is a part of their constituent materials, or they are affected by sodium chloride due to the proximity to saline water sources, and on the other hand because cementation is one the most common methods for soil stabilization due to its availability and abundance, in this study we have tried to evaluate the effects of sodium chloride in solution form on CBR resistance and compaction parameters of the initial selected soil as well as soil stabilizing by cement mixes (according to the proportion of different cement percentages). The obtained results indicate that, adding the sodium chloride in solution form to the initial soil as well as soil stabilized with cement (considering different percentages) will increase the maximum dry density and also decreases optimum moisture, compared to its initial state. Also, adding this solution to the soil will increase the CBR resistance of both types of soil samples (initial and stabilized) considering the amount of different effectiveness on the initial soil and soil stabilized.
