Abstract

The present study evaluated the physical, mechanical and thermal properties of the foam glass aggregate and insulation foundation with this, in order to promote the use of insulated foundations using domestically produced foamed glass aggregates. As a result of the evaluation, the compacted foam glass aggregate showed at the same level as overseas products in terms of unit volume mass, particle size and other characteristics, and a compressive strength of 40.6 N/cm2, which was superior to the existing organic insulation materials such as XPS. And the thermal conductivity of the foam glass aggregate was 0.84 W/mK, and the thermal transmittance of the specimen simulating the insulation foundation was 0.37 W/mK, so the thermal conductivity of the foam glass aggregate was estimated to be 0.80 W/mK. With these results, it was found that it is possible to use the insulation foundation with re-producted foam glass aggregate by crushing the waste from the process of producing foam glass products.

본 연구는 국내 생산 발포유리 골재를 활용하여 단열바닥기초로 활용하기 위해, 발포유리 골재로 구성된 단열부의 물리역학적 특성 및 열적특성을 평가하였다. 평가 결과, 압축강도는 기존 유기단열재인 XPS, EPS 등에 비해 높은 40.6 N/cm2로 나타났으며, 열전도율은 0.84 W/mK로 나타났다. 또한 단열바닥구조를 모사한 시험체의 열관류율은 0.37 W/m2K로 나타나 실제 발현되는 발포유리 골재의 열전도율은 0.80 W/mK으로 평가되었다. 본 연구를 통해 발포유리 골재를 사용한 단열바닥구조의 활용가능성을 확인할 수 있었다.
