Fiber Reinforced Concrete (FRC) clearly improves the load carrying capacity and energy absorption compared to normal concrete. Various types of industrial fibers such as steel, carbon, glass, polypropylene, nylon and others have been used to reinforce the thick concrete in which lathe scrap waste is not explored as compared to other wastes. In this work, lathe scrap steel fibers has been mixed in different proportion in M25 concrete mix design and mechanical properties of the produced material has been evaluated by measuring slump, compressive strength and flexural strength of the moulds manufactured. Sieve analysis has been carried out both for coarse and fine aggregates used in the mixture. Materials are prepared by mixing and casting 0.0%, 0.1%, 0.25%, 0.5%, 0.75%, 1%, 1.5% and 2% ratio of scraped steel fiber produced from lathe waste in M25 concrete mix design by weight of cement. Cube specimens of size 150 mm3 are prepared to test compressive strength of the moulds after 7, 14 and 28 days of curing. Similarly prism specimens are prepared of size 500*100*100 to test flexural strength of the materials. Workability has been check by taking slump test which falls in 50-60 mm. Experimental results shows increase in compressive strength after 28 days of curing from 33.32 kN/mm2 to 38.53 kN/mm2 when 0.25% and 2% of lathe scrap fiber is used respectively. Similarly increase in flexural strength is noted after 28 days of curing which is 1.88 Mpa (MegaPascal) for material having .25% of scrap fiber and 2.28 Mpa for 2% of lathe scrap fiber.
