The amount of lathe waste generated by lathes and CNC machines is 1200 million tons per year, and they are difficult to recycle. The effect of adding Lathe machine waste without pre-cleaning (covered with production lubricants and cooling oils) on the properties of concrete was investigated. A total of 24 concrete castings were cast out of which 6 were without fibers and the remaining 18 were with fiber dosage of 0.4%, 0.8%, and 1.2% by weight of cement for the concrete of M30 grade and were tested for their compressive strength and split tensile strength as per relevant Indian standard specifications The slump cone, air content, pH value, density, compressive strength, tensile strength, tensile splitting strength, elastic modulus, Poisson’s ratio, and thermal parameters were tested. The results of the slump cone test indicates the addition of different weight dosages of lathe scrap fibers to concrete has various effects on the ultimate workability of the concrete. The results of the compressive strength test show that the compressive strength gradually increases when the percentage of fiber weight dosage is increased, it has a maximum value of compressive strength for 1.2% fiber weight dosage. Furthermore, the Tensile strength test shows that different dosages of lathe scrap fibers also affect the ultimate capacity of concrete in tension. It shows that a 0.4% fiber weight dosage rate was the optimum dosage applied to the concrete.
