Experimental Study On Partially Replaced Concrete With Automobile Industries Wastes

Abstract

In recent days, the major threat to our environment is waste management. As a contribution to save our environment many research works are happening to utilize waste in their manufacturing process to reduce waste as well as reducing the cost involved in the process. Waste utilization will partially help us to protect our environment. In this paper, for manufacturing concrete with partially replaced fine aggregate is experimented. The objective is to reuse the locally available polypropylene fibre generated as waste by automobile industries. The adhesion between polypropylene fibre and cement matrix is considered as an important factor. To give proper matrix between the fibre and cement, shredded polypropylene fibre is used as partially replaced fine aggregate. The replacement percentages used are 20%, 40% and 60%. The specimens were prepared with water cement ratio 0.5 and tested after 7days and 24 days of curing period. The influences of polypropylene fibre in concrete in fresh and hardened state are compared with conventional concrete properties. The results obtained shows increase in the strength and workability property for 20% replacement of polypropylene fibre as fine aggregate in concrete. Hence the disposal of polypropylene waste from automobile industry can effectively be used in shredded form as partial replacement of fine aggregate in concrete.
