Abstract—This project work emphasis on the study of using lathe scrap as fibre reinforced concrete in the innovative construction industry. Every day about 8 to 10 kg of lathe waste are generated by each lathe industries in the Pondicherry region and dumped in the barren soil there by contaminating the soil and ground water, which creates an environmental issue. Hence by adopting proper management by recycling the lathe scrap with concrete is considered to be one of the best solutions. The test were conducted as per the Indian standard procedure for its mechanical properties such as flexural, split tensile, compressive, and impact strength and compared conventional PCC. The 7 days strength of the Lathe scrap reinforced concrete shows an increase in its compressive strength when compared with PCC, and almost become equal to the strength when tested on 28 days under normal curing. The addition of lathe scrap in concrete has increase the performance of beam in flexural by 40% when compared with PCC. There is only a considerable increase in the split tensile strength of concrete with lathe scrap when compared with PCC. The workability of fresh concrete that containing different ratios of lathe scrap was carried out by using slump test. The result showed that addition of lathe scrap in to PCC mixture enhanced its compressive strength while it decreased the workability of the fresh concrete containing the lathe scrap. The impact strength of concrete mixed with lathe scrap shows increased impact strength when compared with PCC.
