A Study on the Friction Angel of Cox’s Bazaar Sea Sand by Adding Recycled Plastic Chips

Abstract

Sea sand is that type of soil which is abundantly available, does not contain any organic content; the gradation of this soil is naturally good and can be mined at a low cost. The strength of this soil can be improved by using various methods. This study is mainly focused on the strength behavior of sea sand by adding recycled plastic chips of various percentages. The main reason for using plastic chips is that plastic materials should be used in a constructive way. As the usage of plastic materials is increasing day by day, it has become a great threat to our society and environment. In this study, used plastic bottles are altered into plastic chips and then these are mixed up with sea sand which was collected from Cox’s Bazar and plastic chips of 5, 10 and 15 percent were mixed. Direct shear test has been conducted to check the friction angel the sea sand. According to the results it is seen that the angle of internal friction of sea sand does not improve much by adding different percentages of plastic chips with the mother soil.
