Partial Replacement of Fine Aggregates with Waste Plastic in Concrete

Due to the rapid growth of population in many developing 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 basic of the physical property and how they react with the temperature. As the plastic waste is non-degradable, it must be recycled or reused. The objective of the study is to study the behaviour 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 recycled plastic waste is used as the replacement of the sand in the concrete. Concrete cubes were casted taking 20% to 50 % of plastic as partial replacement of sand and tested for 7, 21, 28 days of the compressive strength. These test revealed that the optimum replacement of the recycled plastic material was 20% to 30% of the weight of the sand used in the concrete.
