Waste Upcycling in Construction: Geopolymer Bricks at the Vanguard of Polymer Waste Renaissance

Abstract

Geopolymer concrete is one of the new aged concrete that is widely being studied and applied due to its sustainable approach achieved by its low CO2 emission by eliminating the utilization of cement in concrete. Geopolymer is cement less concrete made out of industrial by products like fly ash, GGBS, Rice husk ask , Mine tailing waste etc. or any other waste material that constituent the Si:Al that can be dissolved and polymerise in the alkaline solution. In the present study we have utilized rice husk ash to develop the geopolymer concrete as rice husk ash is one of the major challenge of handling and large emission of CO2. The geopolymer concrete made out of Rice husk ask is tested against all the standard codal provision for the conventional concrete. Compressive strength results align with the special mix design made out for the geopolymer concrete. The Study was conducted at the ambient temperature as well at the 60°C and microscopic studies were performed to analysis the change in the internal structure using SEM images
