A Review on Partial Replacement of Fine Aggregate by Waste Paper Sludge in Concrete

The rapid increase in construction activities leads to scarcity of conventional construction materials such as cement, fine aggregate and coarse aggregate. Researchers are being conducted for finding cheaper materials. In India, there are many industries producing large amount of effluent treatment paper waste sludge which leads in problems of disposal. In the Pulp and Paper Industry several types of solid wastes and sludge are generated. Solid waste is mainly produced from pulping, deinking processes and wastewater treatment. The waste generation is strongly affected by the production process and wastewater treatment technologies. Paper manufacturing is a highly capital, energy and water intensive industry. In India, around 905.8 million m3 of water is consumed and around 695.7 million m3 of wastewater is discharged annually by this sector. The amount of waste generated in paper production varies greatly within different regions, because of different recycling rates. The purpose of this study is to find an alternate source for Fine aggregate, cement and as an admixture. In this project concrete was tested with w/c ratio of 0.45.
