AN EXPERIMENTAL INVESTIGATION OF PARTIAL REPLACEMENT OF CEMENT BY PAPER SLUDGE ASH

Concrete is strength and tough material but it is porous material also which interacts with the surrounding environment. The durability of concrete depends largely on the movement of water and gas enters and moves through it. To produce low cost concrete by blending various ratios of cement with paper sludge. It least to reduce the disposal and pollution problems because to paper sludge it is most essential to develop profitable building materials. The innovative use of paper sludge in concrete formulations as a supplementary cementations material was tested as an alternative to traditional concrete. This research work is concerned with experimental investigation on strength of concrete and optimum percentage of the partial replacement by replacing cement via 5%, 10% and 15% of paper sludge. These tests were carried out to evaluate the mechanical properties like compressive strength and split tensile test up to 28 days. As a result, both compressive and split tensile test shows that strength increased up to 5% and further increased in paper sludge reduces the strengths gradually. While testing more than 5% strength of concrete is decreasing because of cement bonding capacity is slightly more than paper sludge ash. So we can adopt 5%. The mix design was carried out for M25 grade concrete as per IS: 10262-2009.
