Effect of Different Stabilization Agent on Shear Behavior of Sand

Abstract

Stabilisation of soils is one of the area that catch interest of many research. Making soil more stable and ready to resist again more loading are the reasons behind the applications. Recently usage of by-product in soils gained a momentum due to the positive environmental effect in terms of removing waste. In this research, three different stabilsation samples were prepared. The stabilization materials effect on the shear strength of sand were compared. The samples were properly blended and checked for homogeneity. All of the mixes apart from sand, had 10% of either flyash or fibre. In order to investigate the effect, direct shear test was used and run in different normal stresses (i.e.50 kPa,100 kPa,150 kPa). After running the direct shear test, the peak values of shear at failure was recorded relevant to each sample and normal stresses. Then the failure envelope plotted for each trial and the results of cohesion and friction angle were compare. The results showed that powder form of material were more effective due to their bonding forces with sand particles.
