Saviour, the Future Concrete

Sustainable development. As India is a fastest growing country in the world. Therefore developing nation the prime requirement is the infrastructure for the industries and offices. Geopolymer concrete is such a one and in the present study, to produce the geo-polymer concrete the Portland cement is fully replaced with fly ash and the fine aggregate is replaced with quarry dust and alkaline liquids are used for the binding of materials. The alkaline liquids used in this study for the polymerization are the solutions of Sodium hydroxide (NaOH) and sodium silicate (Na2Sio3). Different molarities of sodium hydroxide solution i.e. 8M, 10M and 12M are taken to prepare different mixes. The compressive strength is calculated for each of the mix. The cube specimens are taken of size 150mm x 150mm x 150mm. The Geopolymer concrete specimens are tested for their compressive strength at the age of 7days.Mix proportion of M20 grade i.e 1:1.5:3 and w/c of 0.46 was selected and 30% of mix proportion of concrete gives maximum strength than natural aggregate concrete i.e 19.8 N/mm2 on 28 days.
