Utilisation of Waste Plastic Bottles for Manufacturing of Blocks

Abstract

Plastic is light weight and resistant material capable of being fabrication in various ways. Nowadays, large number of plastic bottles are wasted and disposed every day. To construct building the plastic bottles are useful. Waste plastic bottles provides thermal comfort while being sustainable. Waste plastic bottles are nonbiodegradable and its disposal has always been a problem therefore utilizing the waste plastic bottles for manufacturing of concrete block, we are using the plastic bottles in the form of crushed mixed in the concrete material in three different grades (M15, M20, M25). Normal concrete cubes are made up of all the conventional concrete materials such as cement, sand, water, coarse aggregate and fine aggregate. Plastic is economical and lightweight material and hence used as binding material in the concrete cubes. Concrete blocks are prepared with normal concrete materials and concrete materials with waste plastic bottles. Compressive strength of normal concrete block and concrete block with plastic bottle are tested at 7 days, 14 days and 28 days. It is found that compressive strength is more for concrete blocks with plastic bottles than concrete blocks with normal materials.
