Portland cement is the most important ingredient of concrete and is a versatile and relatively high cost material. Large scale production of cement is causing environmental problems on one hand and depletion of natural resources on other hand. This work examines the possibility of using waste paper sludge ash to produce a low cost concrete by blending various ratios of cement with paper sludge ash and to reduce disposal and pollution problems due to waste paper sludge ash. The innovative use of waste paper sludge ash in concrete as a supplementary cementitious material was tested as an alternative to fibre reinforced concrete. In this study waste paper sludge ash was partially replaced from 5 %, 10 %, 15 % in cement to get optimum point and from this optimum point addition of glass fibres with different proportions i. e from 0.1 %, 0.2 %, 0.3 %, 0.4 % and also steel fibres with different proportions i. e from 0.5 %, 1 %, 1.5 %, 2 % are used in concrete for M25 mix and tested for its compressive strength, splitting tensile strength and flexural strength up to 28 days of strength and compared with conventional concrete. Durability tests are also conducted for these mixes with 5 % of H2So4 and HCl. Test results indicate that use of waste paper sludge ash in concrete has improved the performance of concrete in strength aspect
