This is an experimental study on the structural behavior of reinforced concrete beams using of the oyster shells as a substitute fine aggregate of concrete. In this study, the main factors consist of the grain sizes, the percentage of substitution of oyster shells to fine aggregate and the water cement ratio in the same size beams. The results of the study showed as followed. The initial load value of them represented similar constant within 10% of the maximum load value in each test beam. But the maximum load value and the ultimate load value decreased with increased grain size and the rate of substitution. As the grain size of oyster shells became smaller, the load values of them were somewhat higher. The deflection of reinforced concrete beams with oyster shells represented typical curve like that of normal reinforced concrete beam. In the deformation of the steel and concrete, the deformation was proportionated to the load until the yield point and after the yield point it was approached the ultimate load point.: One type was typical curve of the load and the deformation and the other type irregularly was changed to very small deformation with the load increase centering around load axis. It also has proved the good coincidence between the results of the experiment and them of the theory. After analyzing the structural behavior about the above mentioned test beams, the most excellent grain size of oyster shells represented 5.0mm and less with taking the uniform quantity, and the percentage of practicable substitution of them to fine aggregate was about 30% in other to make superior reinforced concrete beams containing oyster shells.
