摘要:
Geopolymer concrete in recent years has come up as an remarkable solution to reduce the carbon footprints of cement industry thereby reducing its production by completely replacing it with other binders alternatives and making use of polymerization process using alkaline activators such as Sodium silicate, Sodium Hydroxide which activates the alumino-silicate binder and forms a 3D polymeric chain which thereby helps in proper strength development of Geopolymer Concrete. Many cements like products which are mostly fine ashes are being brought into use to analyse their response of replacing it in the mix with cement to analyse their behaviour as to what makes the Geopolymer concrete mix more robust and also the noticing the change in the physiological and chemical aspect. After successful implementation of Fly Ash which is an industry by product, now the agricultural by-products which are fine to satisfactory level are being tested to make concrete strong, and durable. This crucial and necessary development has brought keeping in mind the environment's daily degradation because of the industries set up a carbon emitting source in their proximity which has to be readily dealt effectively over years. In this paper, we studied developments in Geopolymer concrete, design mixes and used agricultural as well as industrial by products for the use in the Geopolymer concrete and formulate all the research studies done on the production of most conclusive Geopolymer Concrete and make a standard comparison on what seems to be the most economical, durable and consistent mix of Geopolymer concrete, which comprises of various types of binders including Fly Ash, a byproduct of coal obtained from thermal power plant; Sugarcane Bagasse Ash, a byproduct of sugar mill industry; Rice husk ash, which is the ash obtained of the byproduct of rice mill industry.
