Abstract

This study analyzes the thermal performance of insulating concrete based on material combinations aimed at carbon reduction. The study compares the thermal and structural properties of insulating concrete enhanced with perlite and EPS (Expanded Polystyrene) beads to conventional concrete, with a focus on the impact of insulation properties on thermal conductivity. The results indicate that the content of EPS beads is critical to the insulating performance, and increased moisture absorption significantly reduces the energy efficiency of the insulating concrete. These findings provide valuable insights for the design and application of insulating concrete to enhance energy efficiency and reduce carbon emissions. This study offers guidance for further developing insulating concrete as a carbon-reducing building material.

본 연구는 펄라이트와 EPS Beads를 활용한 단열 콘크리트의 열전도율과 구조적 특성을 분석하고, 물 흡수와 단열 성능 간의 상관관계를 규명하였다. 실험 결과, EPS Beads의 함유량이 4.2%일 때 가장 낮은 열전도율을 나타냈으며, 펄라이트의 함유량 증가에도 불구하고 열전도율의 변화가 나타나지 않았음을 확인하였다. 또한, 단열 콘크리트의 물 흡수를 최소화하는 것이 단열 성능 향상에 중요한 요소임을 발견하였으며, 이를 통해 도시의 탄소 중립 실현에 기여할 수 있음을 제시하였다. 이 연구는 지속 가능한 건축 재료 개발과 에너지 효율 향상에 기여할 수 있는 중요한 시사점을 제공한다.
