Experimental Study on Strength Characteristics of Concrete with Partial Replacement of Cement by Hypo Sludge
Abstract
The increasing amount of wastes is a concerning reality that has arose the sustainability issues for the environment. Large amount of hypo sludge (from paper mill industry). Are generated around 300 million tons annually. Their disposal generally by landfills leads to environmental pollution. Also, the production of cement accounts the global warming by releasing carbon dioxide. The present project work is directed towards developing low cost concrete from paper industry waste. It is carried out with M30 grade concrete with W/c ratio of 0.45 as a control specimen and hypo sludge is replaced in different %ages such as 10%, 20%, and 30% by weight of cement. Cubes of 150mm x 150mm size and Cylinders of 100mm dia and 200mm height, are casted for conventional concrete and RPH (Replacement of hypo sludge by weight of cement) test specimen respectively. Test was conducted to study the mechanical properties of concrete, such as compressive strength and split tensile strength. The curing period should be 7, 14, 21 and 28 days.
