Utilization Of Paper Industry Residue For Producing Supplementary Cementation Material In Concrete - Based On Experimental Investigation

Abstract

Every year almost 300 tons of industrial waste is produced from chemical and agricultural industries. A huge amount of solid waste is generated in paper industry. Recycling of paper fibres can only be done few times before they lose their capacity to generate high quality paper. Therefore, there is a need to investigate about the usage of this waste to produce profitable building materials. Phosphogypsum, flurogypsum, lime sludge, hypo sludge, red mud, and mine tailing pose critical threat to environment. Therefore, generating building materials from these elements would be beneficial for building constructions and it would help to overcome the environmental problems caused by the disposal of this industrial waste. This manuscript deals with production of concrete by utilising cement and different proportions of lime sludge. The aim of this manuscript is to know the concrete compressive strength, acid and sulphate resistivity by replacing cement with 0 %, 10%, 20%, 30%, 40%, and 50% lime sludge.
