Experimental Study on Paper Sludge as Cement Replacement in Cement Concrete

Waste paper sludge is waste product of paper industry, during manufacturing of paper white mud comes out during the process is called paper sludge or hypo sludge or brine sludge. This project is based on the viability of use of waste paper sludge, an industrial waste comes out during manufacturing of paper as partial replacement of cement in cement concrete. Concrete is widely used building material which is used all over the world. Cement which is used as a binding material in concrete contain silica, this cement release poisonous gages during hydration of cement and pollute environment. Although cement is also a costly material, using waste material as partial replacement of cement can save environment and also make concrete economical. Particular this study is based on utilization of paper sludge as partial replacement of cement in concrete, M30 and M40 concrete is manufactured which contains paper sludge 5% to 40% at interval of 5%. Concrete which contains waste paper is tested for compressive strength, flexural strength and split tensile strength, also slump cone test to check workability.
