AN EXPERIMENTAL INVESTIGATION IN CONCRETE BY PARTIAL REPLACEMENT OF COARSE AGGREGATE BY PET BOTTLE CAPS

concrete

Due to rapid growth of population in countries like India the disposing of solid waste is a major problem in our daily life. Solid waste management is one of the major environmental concerns. Among the waste material, plastic is the material that is the major concern to most of the environmental effects. There are different types of plastic which are classified on the basis of the physical property. As the plastic waste is non degradable, it must be recycled or reused. The objective of study is to study the behavior of the concrete which is made of the recycled plastic materials along with the study of the some of the physical properties that are related. Usually M20 grade of the concrete is the most commonly used in the constructional works, hence in this study M20 cement concrete is considered in which the waste plastic bottle caps is used as the replacement of coarse aggregate in the concrete. Concrete cubes were casted taking 10% , 20% and 30% of plastic as partial replacement of coarse aggregate and tested for 7, 14 and 28 days of compressive strength of concrete.
