     Concrete is the fundamental material in civil engineering industry. This project deals with the effect of geopolymer concrete by replacing cement. Cement is the important ingredient in the conventional concrete is the Portland cement. The production of cement in the factory emits enormous amount of carbon-dioxide which pollutes the environment, to prevent this low calcium fly ash based geopolymer concrete is used. Here geopolymers cement is used which is obtained from the reaction of low calcium fly ash with the alkaline solution (i.e.) sodium hydroxide and sodium silicate. It does not pollute the environment and so it is eco-friendly. Metakolin is obtained by Thermal treatment of China clay. It increases the long term strength, durability and resistance to attack in peaty/acidic environments. Fiber reinforced concrete (FRC) may be defined as a composite materials made with Portland cement, aggregate, and incorporating discrete discontinuous fibers. Polypropylene fibers increases the durability of geopolymer concrete. To enhance the curing Metakolin is added. It is proposed to determine and compare the differences in properties of geopolymer concrete with Metakolin and Polypropylene fiber. The investigation are to be carried out using several tests which include workability test, impact value test, sieve analysis, specific gravity test, compression test, split tensional strength and flexural strength.
