Paper Details

This research study presents the experimental work carried out to study the effect of plastic strips on shearbehavior of sand. Here, in this study sand has been used as base material and plastic strips as reinforcement material.Small direct shear box applied as indicator test on sand in reinforced and plain/unreinforced conditions. Grain sizedistribution tests and modified proctor tests were conducted on sand specimens in plain condition. In first attempt directshear tests were conducted under different normal stress conditions on representative specimens of sand inplain/unreinforced conditions and various parameters of direct shear tests were considered. In second attempt sandspecimens were reinforced with random inclusions of plastic strips of different sizes and concentration of 0.1% and 0.2%of the weight of dry soil specimen. Direct shear tests were repeated under different normal stress conditions as followedin case of unreinforced conditions, and various parameters of direct shear tests were considered as followed in case ofplain/unreinforced sand specimens. Results of reinforced and unreinforced conditions specimens were matched. It wasobserved that reinforced sand specimens yields better results than unreinforced sand specimens. An improvement inangle of internal friction of sand was found as 16.67% with plastic strips dimensions of 6x15mm and at concentration of0.2% of weight of sand specimen, so graphs of compression/dilation, shear stress and Mohr-Coulomb envelops of thecorresponding plastic strips dimension and concentration have been presented in this paper.
