ABSTRACT The production of cement results in the formation of carbon dioxide gas which causes the environmental pollution. About 7% of co2 gas is evolved from cement industries into atmosphere; to decrease the liberation of those gases we are partially replacing cement with rice husk ash. Now days the scarcity of sand is the bigger problem in construction industry and fine aggregate is not readily available, hence there is a need to find an alternative material to replace the fine aggregate, such that harm to the environment is prevented. Sugar-cane bagasse is one such fibrous waste product of sugar refining industry which we can use as a replacement of fine aggregate. In this present investigation we are replacing rice husk ash by 5%, 10%, 15% weight of cement and bagasse ash by 10%, 20%, 30% weight of fine aggregate. At optimum percentages of rice husk ash and bagasse ash we are going to add S glass fibers. Here cubes and cylinders are casted for M40 grade of concrete, compression and split tensile tests are conducted and compared with conventional concrete. Keywords: Rice Husk Ash, Bagasse Ash, Compressive strength, Split tensile strength.

INTRODUCTION
Any development action requires a few materials, for example, solid, steel, block, stone, glass, mud, mud, wood, etc. Be that as it may, the concrete solid remains the primary development material utilized in development enterprises. For its reasonableness and versatility as for the evolving condition, the solid must be with the end goal that it can monitor assets, ensure the condition, streamline and lead to legitimate usage of vitality. To accomplish this, major accentuation must be laid on the utilization of squanders and results in concrete and cement utilized for new developments. In current overall business sectors and expanding complement on quality, necessity for concrete having high quality with moderate expense has expanded various folds. Over the previous decades, research on concrete has entered wide based territories of exercises to improve the solid exhibition. The purpose for this isn't just to the immense scope of applications that solid offers, yet additionally because of its extraordinary reasonableness, quality, strength, and flexibility. Various technique has been applied and various types of cement has been presented like, Self - Compacting Concrete (SCC) was presented that improves the strength of the solid, high quality concrete(HSS) was presented that give super high quality. In any case, such cement is seldom accessible and significant expense. The need to diminish the significant expense of Conventional Portland Cement with the alluring attributes a few materials must be changed. From the increased examination into locally accessible items and decrease in cost halfway supplanting of the OPC with rice husk debris is demonstrated to be compelling satisfying necessity. Rice husk Ash is a farming item on which rice husk is singed into remains. RHA is found to be acceptable material which satisfies the physical attributes and concoction sythesis of mineral admixtures. A limited quantity expansion of RHA (lesser than a few by weight of the concrete), to a given water concrete proportion, is adequate and accommodating to improve the dependability, strength too as the functionality will in general increment the compressive quality and toughness of the solid. Utilization of the fine rice husk debris diminishes the temperature when contrasted with the typical opc temperature. As per the scientist perception is was discovered that appropriate proportionate apportion RHA can decrease the starting setting time and furthermore it gets its most extreme quality with a couple of days. RHA depends mostly on silica content, silica crystallization stage, and size and surface territory of debris www.irjmets.com
