Recently, the strenuous industrial waste is scattered and one of the oyster also make the serious environmental contamination. The purpose of this study is investigating an utilization ability as calcium binder of the oyster with Hwang-To according to a rate(10%, 20%, 30%, 40%, 50%). This study grasp physical properties of the oyster powder, bake production of the paste, and conduct the flow test, stiff time test and strength test. According to baking condition, strength of $1000^{\circ}C$(120minutes, rate 30%) is higher than any other condition. The oyster powder from above $900^{\circ}C$ seem possibility as binder hereafter. It is thought that the continuous research will be necessary.
