INTRODUCTION Geopolymer concrete is study investigates about the replacement of ordinary concrete. It is not that much possible for the ordinary concrete to serve as a High Performance Concrete (HPC). So we have to provide some special concrete. Here one such a special concrete is used i.e. Geopolymer concert. This combination will further improve the durability and strength of the concrete and it will increase performance of the concrete than the ordinary concrete. 1.2 NECESSITIES OF GEOPOLYMER CONCRETE Geopolymer concrete is mostly used in highway construction, projects and so on. As per the present world statics day to day and every year millions tons of cement are required. Ordinary Portland Cement is commonly used in concrete. While producing one ton of cement, approximately one ton of carbon di oxide (CO 2 ) will be emitted to the atmosphere, which causes major environmental problems. The high amount of energy is also required for the production of cement. Hence it is very important to find alternative binder. The Thermal Industry produces a waste called as fly ash, which is dumped on the earth and it occupies large areas. The waste water is discharged into the ground from the Chemical Industrieswhich makes impure to the ground water. By the production of Geopolymer Concrete, all the mentioned issues can be solved by rearranging them. Waste Fly Ash from Thermal Industry plus Waste water from Chemical Refineries is equals to the Geo polymer concrete. In this way The production of cement can be reduced and therefore the pollution of atmosphere by the production of carbon di oxide can be decreased. 2. GEOPOLYMER CONCRETE 2.1 GEOPOLYMER THEORY Geopolymer concrete is a concrete that is made by reacting aluminate (Al)and silicate (Si) bearing materials with a Sodium hydroxide. Waste materials such as slag from iron and metal production are used, which helps in leading to a clean environment. Geopolymer concrete does not require any heat for making it and also it does not produces carbon dioxide(CO 2 ). Standard Portland cement concrete are requires both, heat and carbon dioxide. By the contact of the pozzolanic material and the alkaline solutionDissolution occurs immediately, And allows for ionic interface between Species and RESEARCH ARTICLE OPEN ACCESS Abstract: The compressive strength increases with the increasing of fly ash fineness and thus the reduction in porosity can be obtained. Fly ash based geopolymer also provided better resistance against aggressive environment and elevated temperature compared to normal concrete. As a conclusion, the properties of fly ash-based geopolymer are enhanced with few factors that influence its performance. This paper tends to explain constituents of Geo-polymer concrete, its quality and potential applications.
