Abstract

In this study, the engineering characteristics of outer wall insulation panels according to type of insulation materials, their combination, and the contents of insulation materials were tested. Vermiculate, ceramic bead, perlite and expanded polystyrene were used as insulation materials. Flexural strength and thermal conductivity depending on the insulation materials used were measured. It was found that the flow of fresh mortar significantly decreased with an increase in the contents of insulation materials. In terms of the effect of insulation materials on thermal conductivity, an increase in insulation materials resulted in a decrease of thermal conductivity. In particular, PL and EPS, when used together, have lower thermal conductivity than other materials. Regarding the flexural strength of the hardened mortar, the strength showed a tendency to gradually decrease according to the increase in contents of insulation materials, compared to that of the plain mortar. In terms of the flexural strength depending on various types of insulation materials and its combination, it was found that the flexural strength of cement mortar containing 3% of vermiculate(V)+ceramic bead(CB)+perlite(PL) was the highest among the specimens tested.

본 연구에서는 단열소재 종류 및 조합의 치환률 변화에 따른 외벽단열패널의 공학적 특성에 대하여 분석하였는데, 그 결과 굳지않은 모르터의 플로우의 경우 단열소재 치환률이 증가할수록 급격히 저하되는 결과를 나타내었으며, 공기량의 경우 단열소재 치환률이 증가될수록 점차 증가되는 결과를 나타내었다. 경화 모르터의 휨강도의 경우 단열소재 치환률이 증가될수록 전반적으로 플레인에 비해 점차 강도가 저하되는 경향을 나타내었으나 PL 2% 치환 시 증가되는 결과를 나타내었다. 열전도율의 경우 단열소재 치환률이 증가될수록 급격히 낮아지는 경향을 나타내었으며, 단위용적 질량과 열전도율의 상관관계의 경우 단위용적질량이 감소할수록 열전도율은 우수한 결과를 나타내었다. 단열소재 종류 및 조합에 따른 휨강도의 경우 전반적으로 플레인과 유사한 강도값을 나타내었으나 V+CB+PL을 3% 치환한 조합의 경우 모르터 내부가 밀실해짐에 따라 강도값이 증가되는 결과를 나타내어 단열소재 종류 및 조합 가운데 가장 우수한 결과를 도출할 수 있었다.
