This document presents a study on the use of lathe scrap and treated waste water in concrete. The objectives were to study the impact of adding 2% lathe scrap by weight of cement and replacing potable water with treated waste water in concrete. Tests conducted on M20 grade concrete cubes at 7 and 28 days showed increases in compressive, flexural, and split tensile strengths compared to normal concrete. The results indicate that lathe scrap and treated waste water can be used in concrete with potential benefits for construction industry waste reduction and water conservation.
