Eka Sai Kumar PG Student, Civil Engineering Department, K L University, A. P, India V. Raju Assistant Professor, Civil Engineering Department, K L University, A. P, India ABSTRACT Background/Objectives: Water utilisation is the major technological trend in today’s era. India is one of the leading producers of rice and one of its by product rice husk that is obtained during its processing is used mostly as fuel in boilers. With Methods/ Statistical analysis: The concept of new development and thinking, the present paper is done by replacement of cement with rise husk ash (RHA) partially which is an environmental threat is being introduced to concrete mix to reduce the land damage. Addition of RHA may influence it properties. Findings: Concrete mix with different percentages of RHA (i.e., 0%, 5%, 10%, 15%, 20%&25%) the grade used is M25and strength of 7days and 28days are determined by the codal provision. Applications/Improvements: The strength properties are calculated. The main concept of using RHA is economical. In present scenario it may be a unique concept but in near future has a wide range of importance will exist. Key words: Rice husk ash, OPC, Mechanical properties. Cite this Article: Ch.

INTRODUCTION Cement is one of the main ingredient of Concrete. Cement is responsible for 5% of global warming. During manufacturing of cement, one of the green house gases CO2 is emitted. This problem can be minimized by using pozzolonas as replacement of cement. Some of the research works are on going to use industrial wastes such as fly ash, ggbs etc and agro waste like rice husk ash, sugar cane bagasse ash, ground nut shell ash etc were replaced in cement partially. Various researchers had proved rice husk having good pozzolonic properties. India is the second largest country producing rice. Rice husk is the by product obtained in rice mills. Nearly 20-30% of Rice husk is obtained for one tonne of rice grains. Around 20 million tonnes of Rice husk ash is obtained per annum. Its disposal is creating lot of
