Effect of Partial Utilization of Wastepaper Sludge on Strength of Concrete
Galam Ajay Gopi
Abstract: Due to the increase in industrialization, the production of waste generation in the industries is also increasing .to dispose of this waste generated from the industries a large amount of land is needed .to minimize this problem certain effective methods are to be adopted to reduce this problem. One of the methods is utilizing the waste from paper industries in the cement production. Wastepaper sludge is a by-product of papermaking in the paper mill industries considering the physical and chemical properties of waste lime sludge and a series of possibilities for their use in concrete, this work demonstrates the possibilities of using wastepaper sludge together as a partial replacement of cement in concrete. This work represents the compressive strength, split tensile strength, and fire resistance of concrete by adding wastepaper sludge as a partial replacement of cement in various percentages. In this work, cement has been replaced by four proportions of wastepaper sludge i.e., 5%, 10%, 15%, and 20%. It has been observed for the 7 & 28 days test of compressive strength, split tensile strength, and fire resistance of concrete that compressive strength and split tensile increases up to the 10% of waste paper sludge replacement and thereafter a further increase in % of waste paper sludge the compressive strength and split tensile strength decreases compared to nominal mix .on placing the concrete cubes in the furnace at 1000 c and 2000 c temperature for 60 min the compressive strength of concrete is negligible. A considerable decrease in the compressive strength is observed at 3000, 4000, and 5000 respectively.
