Fly Ash is one of the major waste materials available from thermal power plants. Fly ash based geopolymer concrete has suitable properties for its use as a construction material. So here a review has been carried out about the performance of concrete using fly ash as the major binding material with nanosilica and silica fume. This study revealed the Properties, Performance, and applications of geopolymer concrete in the real world. the geopolymer concrete can be used as a building material in a effective ways and it is one the way to reduce the dumping of fly ash waste in environment. Key Words: Geopolymer Concrete, Fly Ash, Strength, Curing, Applications 1. INTRODUCTION Ordinary portland cement (OPC) has been traditionally used as the binding agent in concrete. However, it is also necessary to search for alternative low- emission binding agents for concrete to reduce the environmental impact caused by manufacturing of cement. Geopolymer, also known as inorganic polymer, is one such material that uses by-product material such as fly ash instead of cement. fly ash based geopolymer concrete has suitable properties for its use as a construction material.[1] In 1978, Davidovits et al proposed that an alkaline liquid could be used to react with the silicon (Si) and the aluminium (Al) in a source material of geological origin or in by- product materials such as fly ash and GGBS to produce binders.[2] Therefore ,the objective of this paper is to review the study of the different strength properties of geo-polymer concrete and mix proportion of Geo-polymer concrete with fly ash, silica fume and nanosilica. 2. REVIEW OF LITERATURE 2.1 GEOPOLYMER CONCRETE V.Bhikshma et.al (2012) this demonstrates that range of NaoH molarity of the NaoH range the 8 to 16 were done and standard cubes of 150*150*150 mm size were cast and tested for the compressive stress at the age of 28 days of their casting the test result of the trial mixes the experiment has been taken. Totally 5 mix proportions with chemical ratio’s range from Ͳ.͵Ͳ to Ͳ.ͳͷ were adopted. The compressive strength of the concrete is found to be ranging from 25.00 Mpa to 30Mpa. Splitting tensile strength of concrete is found to be ranging from 4.00 mpa to 5.00 mpa. Similarly the flexural strength of the concrete is ranging from ͷ.ͲͲmpa to ͸ .ͲͲ mpa. )t’s higher the concentration of sodium hydroxide solutions results in higher compressive strength of the fly ash based geopolymer concrete[16]. Raijiwala.d et.al (2011) reported in this paper that an attempt is made to study strength properties of geopolymer concrete. Compressive strength of geopolymer concrete increase over controlled concrete by 1.5 times. The split tensile strength of geopolymer concrete increased over controlled by 1.45 times and flexural strength of gpc increased over controlled concrete by 1.6 times. In durability test, there is decrease in weight loss by 10 times (at 56 days % loss in weight has reduced from 5.66% to 0.66%). Good structural properties can be achieved with increase in polymerization temperature along with prolonged curing period in oven [17]. Joseph davidovits (1991) discussed the result of an the ceramic material like in their structure and properties. These materials can polycondense just like organic polymers, at temperature lower than 1000 c geopolymerization of the chemical reaction alumina- silicate oxides(A13+in iv-fold co ordination) with alkaline polysilicates,yielding polymeric si-o-a 1 bonds the amorphous to semi –crystalline three dimensional silico- aluminate structure are of the policy(sialate) type(-si-o-ai-
