摘要：India is a major rice producing country, and the husk generated during milling is mostly used as a fuel inthe boilers for processing paddy, producing energy through direct combustion and / or by gasification. In reality manyof concrete structures exposed to severe environmental condition exposed to mineral acids present in soil and severeaggressive condition in case of industrial area where there the durability of concrete structure is important. In thepresent study, variations such as water absorption and compressive strengths for 0%, 5%, 7.5%, 10% and 15%replacements of RHA concrete when cured with normal water and 5% NaCl solution is investigated. Forexperimentation process M25 and M35 grade of concrete are selected and variations are studied for 3days, 7days,28days and 56days respectively. It was concluded that RHA concrete cured with 5% NaCl absorbs less water withincrease in replacement proportions of RHA when compared to ordinary concrete. Nacl exhibits early compressivestrength that cannot sustain for longer durations, and maximum strength is obtained at 10% replacement which can beadopted as optimum level.
