The use of waste materials as replacement of natural resources is one of the best approaches to improve sustainability. Paper mill sludge (Hyposludge) is a major economic and environmental problem for the paper and board industry. Most of the wastes sent to dumping sites and landfills. These waste materials could be incorporated in concrete manufacturing as a replacement for cement due to its similar pozzolanic property. From the literature studied it was clear that use of hyposludge in concrete increases compressive strength but on the other hand decreases flexural strength. In order to overcome the decreased flexural strength, fibers could be used. This project involves partial replacement of cement with Hyposludge and also adding steel fibres to improve the flexural strength in M25 grade of concrete mix. The hyposludge replacement percentage was chosen to be 10% and the fibres were added on two different percentages i.e., 0.5% and 1%. The prisms were made and tested for flexural strength. The test showed that 0.5% usage of steel fibres given 7.4% improved flexural strength compared to conventional concrete mix and the 1% fibre proportion showed greater flexural strength of 18.4% higher strength compared to the conventional concrete mix.
