    Abstract :

    India holds second largest producer of cement in the world. The current capacity of cement production is 366 million tonnes. It is expected to reach 550 – 600 million tonnes by the year 2025. Approximately 1 ton of cement production liberates 0.8 ton of Co2¬ to the atmosphere, which pollutes the environment. In this scenario, the geopolymer concrete plays into role, this doesn’t use any quantity of cement.The Main aim of this project is to find out the Strength and Durability characteristics of Geopolymer Concrete especially in Coastal Environment by using combination of Fly Ash, GGBS and M – Sand. The characteristic of fly ash, GGBS and M – Sand is studied and M – Sand was confirmed in Zone III. In this a Mix Design was adopted using M25 grade and then a mix proportion of 1:1.31:1.96 was formulated. The different Molarities of sodium hydroxide solution of 8M and 12M were taken for the preparation of different mixtures. The Test specimens of size 100 x 100 x 100mm Cube, 100 x 200mm Cylinder and 500 x 100 x 100mm Beams were carried out. For the above process steam curing method was used. The Compressive strength of Geopolymer concrete specimen was at 7, 14 and 28 days. The Durability characteristics were also studied.
