Abstract:

The objective of present work is to find out the effectiveness of the Hypo sludge based concrete. In this investigation it was proposed that the partial replacement of ordinary Portland cement by hypo sludge in concrete at variable temperatures. Hypo sludge is the waste material from paper industry that has some chemical properties similar to that of cement. In this investigation percentage of cement replaced partially is (5%, 10%, 15%, & 20%) with Waste paper sludge. Compressive strength of cubes and Split tensile strength of cylinders at 7days and 28 days of duration are studied. The tests are carried out to evaluate the mechanical properties like compressive strength and split tensile strength at 7days and 28 days. And parameter investigated was the time in hours to cause strength deterioration factor at 1000c, 2000c, 3000c, 4000c and 5000c temperatures. Based on the results the optimum level of replacement of waste paper sludge was found to be 10% and change in strength of partially replaced concrete at 100c and 200c is very nominal when compared to the concrete cube tested at normal temperature. Considerable change (decrease) in the Strength of Concrete at 300c, 400c and 500c is observed.
