Abstract：
Through the experiment on the durability of sea sand concrete beam which is subject to long-term chlorine salt corrosion and bending load, the change of deflection, beam load-deflection curve, ductility and crack are studied. The results show: compared with ordinary concrete beam, the sea sand concrete beam which has been subject of chlorine salt corrosion and bending load has a higher rigidity; the deflection amount and the width of crack of this concrete beam all fall in the confines of ultimate service state under use load; and the beam displays a better ductility in failure.
