  • 지구 온난화로 인해 온실가스 배출에 대한 규제가 강화되고 있는데, 온실가스의 주된 성분은 이산화탄소($CO_2$)이다. 건축 분야에서 $CO_2$ 발생량을 줄이기 위해서 저탄소 장수명화가 진행되고 있고 건축자재에 RFID(: Radio Frequency Identification)를 사용하여 자재관리 시스템을 구축하는 사례가 증가하고 있다. 기존의 RFID를 활용한 건축자재 관리 시스템은 건물의 신축단계에서 건설자재가 어디에 얼마만큼 사용되는지에 대한 연구와 실험이 대부분 이었고, 건물의 신축과 해체 시 재활용할 수 있는 자재에 대한 상태관리 시스템은 개발된 사례가 없다. 본 논문에서는 건물의 신축 혹은 해체 시 건설자재의 상태를 효과적으로 관리할 수 있는 RFID 시스템을 제안한다. 제안된 시스템은 900MHz 대역의 RFID를 사용하며 건축 자재 표면 또는 내부에 RFID 태그를 부착한다. 시스템의 구조는 RFID 리더부, 통신부, 저장부로 구성된다.

  • Domestic construction materials market was about 65 trillion won and it occupied 45% level of total construction cost by 2007. In addition, due to the recent rapid rise of crude oil and iron ore price, fluctuation of raw material cost has a great influence to the cost of construction industry. This means that smooth performance is closely related to construction materials. And among them, because of high putting rate of metal materials, it can be seen that the fluctuation of metal material prices is an important variables. So in this study, for the pre-study to analyze the impact of metallic material prices to construction cost, the researcher analyzed a causal relationship between metal material prices and construction cost.

  • This study aims to review the research trends of landscape construction and materials, and to discover the research characteristics in Korea. The research scope was limited to the 905 articles lin the Journal of Korean Institute of Landscape Architecture between 1973 and 2003. The results of the research were as follows. The number of articles concerning landscape materials and construction were few(5.8%), compared to other research fields. The articles were categorized by sequences of the structures, the construction and management, the development of engineering and the development of materials. The articles concerning construction and construction management were categorized into 3 types of quality management; construction and materials, the cost estimation and the work classification and processes. The soils was studied together with plants suited to such soil characteristics as layer, structure, and composition.

  • 국내 건설공사의 규모가 점점 대형화, 복잡화, 전문화 되어가면서 품질향상, 원가절감, 안전 확보, 공기단축 등의 요구는 날로 증가하고 있다. 공기지연 없이 좋은 품질로 공사를 수행하기 위해서는 실시간 건설자재 관리가 매우 중요한 사항이므로, 최근 건설자재관리의 효율성을 위하여 RFID(Radio Frequency Identification)를 이용하는 다양한 연구들이 진행되고 있다. 이에 본 연구는 이러한 RFID의 기술적 특성을 파악하고 RFID에 대한 기존 연구들을 분석한 바탕위에, 건설현장에서 이루어지고 있는 자재관리 현황에 대한 조사를 통하여 문제점을 도출하고, RFID를 적용한 건설자재관리 방안을 제안하고자 한다. 본 연구는 건설자재의 효율적 관리를 통해 정확한 공정관리에 따른 필요자재를 적시에 공급할 수 있는 가능성을 제시할 것이며 이는 건설생산성의 향상으로 귀결될 것으로 예상된다.

  • The purpose of this study is to develop standard reference materials for safety control of construction materials considering the required performance of standard materials including flow performance incorporating particles. The flow characteristics of concrete are very complicated depending on mixing proportions of constituent materials, admixtures, amount of mixing, type of mixer, time of mixing, temperature and so forth. Uncertainties and multidimensional properties of concrete have been evaluated through various studies but there are few researches for the development of standard reference material. In this study, based on the rheological concept, the flow performance of construction materials was evaluated to understand the properties of standard reference materials and was finally obtained representing materials which simulate the standard reference materials.

  • Since the protection the of human being from natural disaster and atmospheric factors have become an essential requirement, some attempts have been taken place to provide shelter and create a safe environment to a more comfortable life with welfare. For this purpose, using existing resources in nature and exploiting them in a different manner have been taken into account. Initially, the performed exploitations for construction had the least damage to the environment, but over time and as a result of population growth, aggressive exploitation of nature has led to destroying effects on the environment and resulted in consequences such as pollution and environmental destruction. Thus, the construction industry has been identified as the top pollutant factors of the environment. Among various construction factors, the building materials used in this industry are considered as the most important effective factors on the environment, as they have direct influences on the environment from the beginning of construction of the final steps. This research focuses on the review of the most of the existing green materials definitions and various approaches towards using eco-efficient construction materials. It presents and discusses possible ways of reducing the destructive effects on the environment by selecting and using green materials, review current literature and highlight the necessity of applying such materials in future constructions in all communities. This paper provides a base for this purpose that sustainable development communities and environment is realized by elimination of environmental pollution and approaching the criteria of green building by using sustainable materials.

  • Changes in the price of materials in construction projects is one of the important variables. Therefore, measures are necessary to respond to the demand and supply of materials and price instability. In previous studies, mainly of ready-mix concrete and steel beam analysis was carried out. However, a study of non-ferrous material prices are still insufficient. So, in this study, the researcher identified the causal relationship between the construction cost and non-ferrous materials prices. Construction Cost Index was selected as a proxy variable of construction cost.

  • 본 연구에서는 EN 13823 기준을 적용한 시험방법인 SBI(Single Burning Item)을 이용하여 스티로폼 샌드위치패널의 화재특성에 대한 실험을 실시하였다. 현재 국내에서는 샌드위치패널 화재특성 평가방법으로 ISO 5660-1(콘칼로리미터 시험방법)과 KS F 2271(난연성시험)이 사용되고 있지만 이러한 시험방법들은 시험 스케일과 시험편 및 가열조건의 한계점 등을 보이고 있다. 따라서 본 연구에서는 1세트를 3개로 하여 총 9개의 75mm 두께인 스티로폼 샌드위치 패널을 이용한 실험을 실시하였다. 이를 통해 공학적인 화재 물성 값인 FIGRA(FIre Growth RAte, kW/s), SMOGRA(SMOke Growth RAte, m2/s2)등을 측정하였다.

  • Construction work in island areas requires the materials to be transported by ship and plane, and it causes an increase in the construction costs. In addition, the construction work near marine zones may produce the marine pollution due to the harmful substances in the cement. Recently, nature-friendly construction materials are increasingly used, and there is a need to select and develop appropriate construction materials. In this study, the compressive strength, tensile strength, flow and chloride content of the mortar mixed with cement and muddy tidal flat were measured to reduce the amount of cement by applying the natural materials, muddy tidal flat and marine sand, and the results were provided as the basic construction material data.
