Concrete Made By Paper Sludge

Abstract

To produce low-cost concrete by blending various ration of cement with paper sludge and to reduce disposal and pollution problems due to paper sludge. It is most essential to develop profitable building materials from paper sludge. Innovative use of paper sludge in concrete formation as a supplementary cementitious material was tested as an alternative to normal concrete. In this study, paper sludge was physically and chemically characterized and partially replacement in the ratio of 0%, 20 %, 30 %, 30% of paper sludge +20% of fly ash by weight of cement, natural river sand as fine aggregate, and normal coarse aggregate were used to produce concrete. Present study gives us an idea about how concrete’s mechanical properties like compressive strength, split tensile test and flexural strength & fresh properties like slump behave if we replace a cement with hypo-sludge to a certain extent. keywords concrete , hypo-sludge, compressive and flexural strength, paper waste, _____________________________________________________________________________________________________
