Abstract

One of the several methods for ground improvement is adding different materials to soils. Accordingly, two materials, including glass fibers and nanoclay, are used in this experimental research to stabilize aeolian sand in Yazd city in Iran. In this study, the standard compaction test and the direct shear test were carried out to investigate the effect of additives mentioned on aeolian sand. The aim of this study was to use a percentage of glass fibers, which produced the highest internal friction angle in the soil, with three different percent of nanoclay. The results of the compaction test showed that by increasing percentages of glass fibers, the optimum moisture percentage is increasing, too. It was concluded that adding these materials to the soil was increasing the shear strength parameters of the soil. Moreover, soil composition with selected percentages of additives causes the cohesion of natural soil to double.
