This study is performed to evaluate the physical and mechanical properties and acid-resistance of oyster shell concrete. The result shows that the unit weights of concrete with oyster shell are decreased by 1∼2% than that of the normla cement concrete. The highest strength is achieved by 2.5% oyster shell filled oyster shell concrete, it is increased compressive strength by 4% , tensile strength by 6% and bending strength by7% than that of the normal cement concrete, respectively . The acid-resistanceis increased with increase of the content of oyster shell. It is 1.6 times of the normal cement concrete by 15% oyster shell filled oyster shell concrete. Accordingly, oyster shell concrete will improve the properties of concrete.
