Abstract - Concrete is the world’s most versatile, durable & reliable construction material. The production of Portland cement contributes at least 5 to 7% of carbon dioxide which polluted the atmosphere. We try to reduce the pollution by the usage of industrial waste products. We use the fly-ash as a replacement of cement but not used as total replacement which is used as a 10%, 20%, 30%. Alkaline material used as binding material which is sodium hydroxide (NaOH) and sodium silicate with different molarities i.e. 8M, 10M, 12M are taken to different mixes. The cube sizes of 15 × 15 × 15 𝑐𝑚 are for compressive strength of geopolymer concrete. The specimen tested after 7, 14, 28 days. The result shows that strength of geo-polymer concrete is increasing with increase of molarity of alkaline material. The use of Portland cement in concrete construction is under critical review due to high quantum of carbon dioxide gas released to the atmosphere during the product of cement. In recent times, attempts to increase the application of cover ash to incompletely replace the use of Portland cement in concrete are gathering instigation. Utmost of this by product material is presently ditched in tips, creating a trouble to the environment. Fly ash was chosen as the introductory material to be actuated by the geo-polymerization process to be the concrete binder, to completely replace the use of Portland cement. The binder is the only contrast to the usual Portland cement concrete. To spark the Silicon and Aluminum content in cover ash, a combination of sodium hydroxide result and sodium silicate result was used.

Key Words: Polymer concrete, fly ash, compressive strength, tensile strength, Temperature.
