Experimental Investigation On Properties Of Concrete Using Lime Sludge As Partial Replacement

Abstract

Paper industry produces an enormous amount of solid waste.The paper fibres can be recycled only for certain number of times to produce high quality paper.Hence, it is of prime concern to develop methods to use this waste to produce affordable building materials.Lime sludge can be used as a supplementary cementation material in concrete composition,which is tested as an alternative to standard concrete.This manuscript deals about generating low-cost concrete by combining various ratios of lime sludge with cement and to eliminate disposal and pollution problems caused by lime sludge.Various tests were undertaken to assess the mechanical parameters, like, concrete compressive strength, sea water resistivity and sulphate resistivity by replacing cement with 0 %, 10%, 20%, 30%, 40%, and 50% lime sludge.
