It is not possible to replace the paper waste for innumerable number of times. Since the paper fiber, after multiple recycling processes, becomes weak broken and unsuitable for manufacturing paper high quality. Thus the broken and low class paper fibers are alienated in order to make waste sludge known as hypo-sludge, which is available at very negligible rate and in huge quantity from paper industry. Hypo-sludge has a very good content of CaO from CaCO3, SiO2, and MgCO3.This study probes the feasibility of using hypo-sludge by partially replacing the lime in making fly-ash bricks. The replacement of hypo-sludge by weight among lime of 5%, 10%, 15% and 20% is done in this study. These bricks were tested in compression test and water absorption test as per Indian Standards. The research aims at making economical and green bricks so as to maintain environmental balance and avoid the problem of ash disposal. Countries like India suffer from low availability of non-renewable resources and huge need building materials like cement and brick earth. Therefore it is essential to develop eco-efficient utilization of paper sludge. Combined with various proposition of mix and various tests are to be done make same the compressive strength, water absorption and the economical feasibility of the bricks.
