A STUDY ON USE OF RECYCLED PLASTIC (HDPE, LDPE & AMP; VHDPE) IN CONCRETE AS A PARTIAL REPLACEMENT OF COARSE AGGREGATE TO OBTAIN LIGHT WEIGHT CONCRETE Abstract
The project aims at use of recycled plastic i.e. High density poly Ethylene (HDPE), Low density poly Ethylene (LDPE), Virgin High density poly Ethylene (VHDPE), in concrete as a partial replacement of Coarse aggregate to obtain light weight concrete. The waste plastic of HDPE, LDPE, and VHDPE is collected from Hyderabad and mixed with PPC and sand in varying proportions (0%, 10%, 20%, and 30%). The compressive strength for each variant is to be determined in laboratory. The rapid industrialization and urbanization in the country leads lot of infrastructure development. This process leads to several problems like shortage of construction materials, increased productivity of wastes and other products. As disastrous effects of waste plastic on the environment is noticed by the authors as its huge quantity pollutes the environment, therefore authors have taken up this study.
This study deals with the reuse of waste plastics as partial replacement of coarse aggregate in M20 concrete. Usually M20 concrete is used for most constructional works. Waste Plastics were incrementally added 0%, 10%, 20%, 30%, to replace the same amount of Aggregate. Tests were conducted on coarse aggregates, fine aggregates, cement and waste plastics to determine their physical properties. Cubes of concrete were cast and tested after curing them for 3, 7, 14 and 28 days for compressive strength. The result shows that the compressive strength of M20 concrete with waste plastics HDPE, LDPE, VHDPE is highest at the replacement of 20% for cube strength but still it is less than the normal concrete. Hereafter increment in percentage of it is decreasing the strength.
