Hypo sludge is a material procured from the chemical recovery process of paper production & waste steel scrap available from the lathe is used. In the present appraisal, the effects of Hypo-sludge as a limited renewal of 5%, 10%, 15% & 20% to the cement for M50 grade concrete with 0.4 as w/c and uniformly maintaining the addition of 1% lathe waste by weight of cement. Further, in this appraisal, properties of fresh concrete was assessed and prominently found to be workable in nature. Some of the mechanical properties were carried out for different ages (3, 7, & 28 days). Additions of lathe waste have some advantage effect on strength properties up to Mix- 3. From the results, Mix-3 was found to be an optimal replacement in which there is an enhancement in values of Compressive & Split- tensile strength, but Mix-2 showed enhancement in values in flexural strength. An additional durability test was studied by performing water absorption test & observed that increase in the variation of Hyposludge has more water absorption.
