알데히드류는 실내 가정의 건축물 단열재, 실내가구의 칠, 접착제, 하드보드, 악취 제거제, 제지 등 생활 용품에서 공업용품에 이르기까지 광범위하게 사용되며, 그 사용량도 증가되고 있다. 특히, formaldehyde는 urea-와 Phenol-formaldehyde 수지를 합성하는 주요 화합물질이다. 알데히드류 중 포름알데히드는 1ppm 또는 그 이하의 농도로 노출될 경우, 눈, 코, 목의 자극을 유발하고, 농도에 따라서 피부 알레르기, 두통, 메스꺼움, 흥부 압박감, 기관지염, 폐염 및 폐부종을 야기하며, 동물 실험결과, 미국 환경보호처에서는 인체 발암 가능성 물질로 분류하고 있다(US EPA, 1999).

알데히드류는 실내의 다양한 오염원에서 발생되어 하루의 대부분을 실내에서 보내고 있는 현대인들에게 건강상 영향을 미치는 것으로 알려져 관심의 대상이 되어왔으며, 특히, 포름알데히드는 발암성 물질로 알려진 대표적인 실내 환경 오염 물질이기도 하다(Zhang junfeng et al., 1999). 포름알데히드는 urea 또는 phenol-formaldehyde 수지를 합성하는 주요 물질이며, 건축물 단열재, 가구의 염료 및 광택제, 접착제, 합판, particle board, 악취 제거제, 제지, 가스 스토브, 담배연기, 화장용품, 세제등 생활 용품에서 공업용품에 이르기까지 광범위하게 사용되며, 그 사용량도 증가되고 있다(Thomas J. Kelly et al., 1999). (중략)

The term 'thermal insulating materials' describes a class of materials which can improve the thermal efficiency by reducing the thermal conduction, convention and radiation between the inside and outside of the system. As a thermal insulating material, numerous industrial applications are possible including the automobile, aerospace, aviation, and petrochemical. Especially, the silica aerogel, with their superior thermal insulating behavior, has been widely used as thermal insulating materials. Because the mechanical properties of the silica aerogel cannot meet the industrial demand, use of the silica aerogel is limited. This article aims to review the thermal insulating materials and silica aerogel, and to introduce the silica aerogel/polymer composites.

건축물 내 외벽에 주로 사용되는 건축용 자재 중 샌드위치 패널은 양면으로 도장한 철판 사이에 심재로 단열재를 넣어 구성된 합성복합자재이다. 샌드위치 패널의 사용범위는 창고시설 및 공업용 건축 등의 용도로 많이 사용되고 있으며, 최근에는 시공에 따른 이점으로 주택 및 상업용등으로 널리 확대되어 사용되고 있다. 본 연구에서는 화재초기의 연기밀도는 인명 대피 시 시야확보에 있어 중요한 역할을 하기에 현재 국내에서 사용되는 건축용 외장재를 용도별로 선정하여 시간에 따른 연기밀도의 값을 구하고 용도에 따른 화재 연기의 확산 정도를 예측하는데 목적을 두었다.

Glass wool is a material that has been used as a heat insulator in various fields including construction industry. Since it is a nonflammable material, it does not generate toxic gases on fire, and thus public agencies recommend using glass wool as a heat insulator instead of other organic materials. However, repeated drying and wetting cycles can deteriorate thermal property of glass wool due to the shrinkage and reduction in pore size. For this reason, it needs to be replaced periodically, and waste materials are generated. This research aims to utilize waste glass wool as additives for increasing mechanical properties of concrete. According to the experimental results, it was found that glass wool has weak pozzolanic activity, and beneficial effect on both compressive and flexural strength. The optimum amount found in this experimental work was 0.5% volumetric addition to the concrete.

Nowadays in Korea, KS F 2271 has been using for the test of fire safety performance of sandwich panels. Smoke toxicity test is the test for the toxicity evaluation of smoke and hazardous gas, caused by combustion of building materials and finishing materials. Smoke toxicity can be evaluated by the mean incapacitation time of mice; however this method is not a quantitative way. This test result can be influenced by the health status of mice and test condition. Specific optical density can be quantitatively measured by ISO 5659-2 single chamber method and toxic gases can be quantitatively measured by FTIR analysis. In this study, specific optical density of sandwich panel insulations, which are widely used in Korea, were tested using the ISO 5659-2 single chamber test method and compared with each test. Also, in the second test of three tests for each specimen, FTIR analysis was performed and quantitative test results(HCl, $NO_2$, etc) were compared with each test result.

This study investigated the thermal insulation performance of Azon and Azo-Core, two materials commonly used in window frames, for potential application in window shutters. A three-pronged evaluation approach was employed, utilizing the Therm 7.4 software, confidential test results, and dedicated thermal insulation testing. The simulation data indicated that both Azon and Azo-Core offered superior insulating properties compared to conventional shutter insulation materials. When incorporated into shutters, these materials achieved a first-grade sealing performance and a measured average thermal conductivity of 2.018W/m²·K. While this thermal conductivity value surpasses the standard requirements of 1.5W/m²·K for central regions and 1.8W/m²·K for southern regions in Korea, it falls within the acceptable limit of 2.2W/m²·K established for the Jeju region. Based on these findings, Azo-Core, warranting further dedicated research, presents itself as a promising candidate for shutter insulation material, particularly in applications targeting the Jeju region.

Due to the big fire in Uijeongbu, the status of construction, fireproof materials and structural method were examined to prevent fire propagation through outside insulation parts of urban living homes. Through research and experiments, the following results were obtained. It was confirmed that outside heat-insulation wall method was used in a large number of urban living homes which were made of materials and structures spreading fire easily.Through experiments, it was revealed that lightweight plate material, as a fireproof material, can save the cost as well as the period of construction and obtain more than 30 minutes of evacuation time which is twice the maximum evacuation time.

The replacement ratio of waste EPS was varied, and its effect on compressive strength and absorption capacity was investigated. According to the experimental results, The 28th day compressive strengths for the W/C 50% specimens were 17.5~21.2MPa, which was relatively low compared to the 13.6~22.2MPa of the W/C 70%.

Recent government policies are increasing interest in zero-energy housing, a building that minimizes energy consumption (90% reduction). As the importance of building passive performance is emphasized, the role of insulation is increasing as a way to reduce indoor heat loss in order to minimize the use of cooling and heating energy. There are two main types of insulation. Organic insulation is widely used for various construction structures such as construction and industrial due to some merits such as the convenience of construction and construction cost. However, it has been pointed out as a main cause every time a fire accident occurs, Jecheon Sports Center', the fire damage of buildings caused by the use of organic insulation materials is expanding to social problems, so it is urgent to research on nonflammable inorganic insulation materials.
