Abstract

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.

본 연구에서는 리빙 콘크리트 패널 설계시, 재료적 측면에서 모재료의 품질을 제어하기 위하여 마그네시아 복합체의 마그네시아 및 인산칼륨 비율에 따른 품질특성을 평가하였다. 품질특성은 W/B는 7수준(30, 35, 40, 45, 50, 55 및 60%), P:M 4수준(1:0.5, 1:1.0, 1:2.0 및 1:3.0 vol. %)에 따라 제조하여 평가하였다. 마그네시아 복합체의 플로우 평가결과, W/B가 증가할수록 플로우가 증가하는 경향이 나타났으며, P:M 증가에 따라 플로우가 감소하는 경향이 나타났다. 마그네시아 복합체의 압축강도 평가결과, P:M이 증가함에 따라 강도가 감소하는 경향이 나타났으나 최적의 배합비율이 존재함을 확인할 수 있었다.
