ABSTRACT This paper concern for the Durability study on Geo-polymer Concrete made with Ground granulated blast furnace slag and Back rice husk ash. We are aware that the production of cement causes significant environmental impact. It involves a significant amount of carbon emissions as well as other substances. According to studies, every tonne of cement produced emits half a tonne of carbon dioxide, indicating that there is an immediate need to limit cement use. On the other hand, materials wastes like BRAH (Black rice husk ash) are difficult to dispose of, posing an environmental risk. BRAH (Black rice husk ash) is a by-product of Thermal Power factories discovered after burning Rice husk, which is discovered after all economically valuable Stream Power has been extracted from Rice husk & GGBS which is produced by grinding Granulated Blast furnace Slag to a controlled fineness.. Because of the increased construction activity in the country, most construction materials, particularly cement, are in short supply, resulting in a steady rise in price. As a result, this study was carried out to see if Black rice hush ash and GGBS (Ground granulated blast furnace slag) may be used as a cement substitute. Black rice husk ash samples were initially gathered from a Thermal Power Plant and their chemical characteristics were studied. Black rice husk ash and GGBS was used in place of Ordinary Portland cement. For 25MPa concrete. Geopolymer concrete is very helpful in providing us a new approach towards sustainability in which various industrial waste products can replace OPC as a binder completely. Reviews specific to Fly ash based and GGBFS based geopolymer concrete have been highlighted. Research findings as mentioned in this paper successfully established geopolymer concrete as a better alternative to OPC based concrete.

INTRODUCTION Concrete is the most predominantly used construction material in the world. The principal ingredient of concrete, Ordinary Portland Cement (OPC) is unfortunately found to be associated with some adverse effects. At the same time, a lot of industrial and agro wastes with inherent cementitious properties are produced abundantly but mostly dumped into landfills. Employing such by-products as alternates for cement has multiple benefits including conservation of environment, sustainability of resources and solving the disposal problem of by-products. One such promising alternative is ‘Geopolymer Concrete’ (GPC) which completely eliminates OPC in its production. Dr. Joseph Davidovits coined the term ‘geo-polymer’ in 1978 to describe a family of mineral binders that can be produced from the polymerization reaction between an alkaline liquid and a source material containing silicon (Si) and aluminium (Al). The source materials of geopolymer could be of geological origin like metakaolin or by- product materials like Black rice husk ash, Ground Granulated Blast furnace Slag (GGBS), silica fume, fly ash, etc. The alkaline liquid used is a combination of sodium or potassium hydroxide along with sodium or potassium silicate correspondingly. GPC (Global product classification) is proven to have superior strength and durability over conventional concrete. Black Rice Husk Ash (BRHA) is an agro-industrial waste obtained by incinerating the rice husk and has a high content of unburnt carbon. Consequently, the use of BRHA as a construction material is very limited, even though it has high silica content about 90%. But, some researchers have reported that the addition of BRHA in concrete has improved its durability property. There are no published works available related to the use of BRHA in Geo-polymer concrete. Most of the research works related to GPC have
