Abstract

Concrete is a strong and tough material but it is a less porous material also which interacts with the surrounding environment. The concrete durability depends on the water movement and gas enters and moves through it.To produce low-cost concrete by blending various ratios of cement with paper sludge.At least to reduce the disposal and pollution problems because to paper sludge it is most essential to develop profitable building materials. The use of paper sludge in concrete preparations as a supplementary cementation material was tested as an alternative to conventional concrete. Present study is concerned with the experimental investigation on strength of concrete and optimum % 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 cement bonding capacity is slightly more than paper sludge ash.
