A study on Partial Replacement of Sand using Waste Plastic and Steel Fibers

The increase of population in world has led to the generation of large amount of waste products such as waste plastic. These waste plastic will remain in the environment for hundreds of years, this has become inevitable problem in the present world. There is an immediate need for solution for such problem. To bring down the waste products many methods has been proposed and one of them is usage of these waste plastic in concrete which may reduce the environmental problems up to certain extent. This work aims to study possibility of disposing waste plastic as fine aggregate in concrete. In this study waste plastic mix concrete is also reinforced with steel fiber to get advantages of fiber reinforced concrete. For this an experimental study was carried out with M25 grade of concrete to evaluate the workability and mechanical property of waste plastic mix concrete with and without the addition of steel fiber. Sand is substituted with plastic waste at a dosage up to 15% by mass and we found that 5% dosage is an optimum percentage without considerable reduction in strength. Results show that adding steel fiber we can improve the quality of waste plastic mix concrete. Thus it can be concluded that replacement of sand by waste plastic up to 5% can be utilized so that disposal of used plastic can be done and hence deficiency of natural aggregate can be managed effectively.
