Geopolymer Brick Using Sludge Waste

Geopolymers are produced by a polymerization reaction of strong alkaline liquids such as sodium hydroxide (NaOH), sodium silicate with the source material of geological origin or by product material such as fly ash, GGBS, metakaolin. The mixture can be cured at room temperature or heat cured. This innovation is mainly focused on the ambient temperature cured geopolymer bricks produced from the Sludge and Industrial waste fly ash, GGBS geopolymer is an alternate material for the construction industry reducing environmental pollution leading to sustainable environment satisfying all the properties. Disposal of sludge waste reduces environmental pollution due to suspended particulate matter (SPM). This experimental investigation deals with the optimum utilization of tannery sludge in production of geopolymer bricks. From the results of compressive strength, water absorption it has been concluded that 30% of tannery sludge can be replaced into industrial waste in production of geopolymer bricks, leading to the sustainable environment.
