In this study, the quality properties according to the ratio of magnesia and potassium phosphate of the magnesia composite were evaluated to control the quality of the parent material in terms of materials when designing living concrete panels. The quality properties are 7 levels (30, 35, 40, 45, 50, 55 and 60%) for W/B, 4 levels for P:M (1:0.5, 1:1.0, 1:2.0 and 1:3.0 vol. %) was prepared and evaluated. As a result of evaluating the flow of the magnesia complex, as W/B increased, the flow showed a tendency to increase, and the flow showed a tendency to decrease as the P:M increased. As a result of the evaluation of the compressive strength of the magnesia composite, the strength showed a tendency to decrease as P:M increased. In addition, it was confirmed that an optimal P:M ratio exists.
