HYPO SLUDGE AS A PARTIAL REPLACEMENT OF CEMENT IN CONCRETE

Present day's development of solid structures has been expanded because of which we need lot of cementing materials has been increased .In this paper we are using Hypo sludge as a partial replacement of cement in concrete. Hypo sludge is the waste produced from the paper industry. In this paper we utilized 5%,10% of Hypo sludge as a partial replacement of cement. At 5% replacement we have noticed that the strength of concrete has increased by 6% to the nominal mix of M-30. On further increment in percentage of Hypo sludge the strength of concrete decreases.
