500			_aABSTRACT Compared with other materials, concrete is the most indispensable building material used in construction, and cement is one of the main constituent of concrete. Mainly to save cots, protect the environment and reduce resource consumption, the use of by-products in the construction industry are being considered to use by-products rather than cement. This environmental threat has forced researchers to use industrial by-products as additional cementations for concrete product ion. I n t h is study, fly ash and rice husk ash were used as a partial replacement of cement at 7 days and 28 days to study the flexural behavior of reinforced concrete beams. Water cement (W I C) ratio remains stable or constant at 0.50. The entire samples were divided into seven batches of B-1, B-2, B-3, B-4, B-5, B-6 and B-7. The dosage or FA & RHA was used in concrete with replacement level of 0% and 10% and 1 5% with an increment level of (50%FA+50%RHA) & (75%FJ\+25%R HA) & (25%FA+75%RHA). Each specimen was cured i n water and tested to evaluate ultimate load and ultimate deflection at 7 and 28 days. The experimental results showed that the maxi mum ultimate load of this concrete containing Fly ash and R ice husk ash was 25.03 KN, minimum ultimate deflection was found to be 2.10 mm with partial cement replacement of 10% (75%FA+25%RH A) at 28 days. Th results reveal that the 10% replacement of cement with FA and RHA (75%FA+25%RHA) may be considered as optimum.
