Scrap which is a waste can be used as reinforcing material in concrete to enhance the various properties of concrete. Scrap from lathe machine act in a same way as steel fiber. In every lathe industry, wastes are available in form of steel scraps which are produced in different manufacturing processes of lathe machine works and dumping of these wastes in the barren land causes the contamination of soil and ground water which builds an unhealthy environment. In this paper, M40 concrete is used and lathe scrap fiber is added with different proportions (0.5%, 1.0%, 1.5%, and 1.75%) to check the strength variations in concrete. In this experiment, three different types of waste metal have been compared with commercial 40, 60 and 72 graded steel reinforcement bar. The fiber used is irregular in shape and with varying aspect ratio.The main idea of this research work is to use waste scrap steel fiber in concrete which provides cost-effective and eco-friendly sustainable development.
