ABSTRACT: Cement manufactured release large amount of carbon dioxide. So there is an instantaneous require to manage the use of cement. This research mainly deals with the replacement of cement by fly ash taken in variable proportions and analysing the effects of fly ash concrete. The concrete mix is prepared by varying the proportions of fly ash for 30%, 40% and 50% of cubes and prisms cured in normal water up to for 7 and 28 days. Compressive strength and flexural strength for hardened concrete are verified and the results are analysed. Key words: Fly Ash, Pozzolanic, Compressive Strength, Flexural Strength Cite this Article: V. Manohar and P.

INTRODUCTION Ordinary Portland cement is the most commonly used building material .It will retain its level in future because of its demand and expansion of construction of industry all over the world, future the greatest challenge faced by the concrete construction is to serve the insist needs of human society which include the environmental safety and gathering the infrastructure requirements of our increasing population. Less than that of cement for obtaining for good bond between cement and fly ash. This project discusses the practical exposure of fly ash. One of the main threats is sulphate attack against concrete structures resultant in loss of load and lessening the strength of concrete. Polluted ground water and sea water by industrial effluents represent some of the sources of sulphate that attack on concrete. The use of blended cement has shown quick results in resisting the sulphate attack on concrete. Fly ash which shows pozzolanic properties is being used as a partial replacement in concrete and is produces as a waste material from pulverized coal manufacturing units which is then finless.
