A porous material with a surface layer was fabricated from glass abrasive sludge and expanding agents. The glass abrasive sludges were mixed with expanding agents and compacted into precursors. These precursors were sintered in the range of $700-900^{\circ}C$ for 20 min. The sintered porous materials had a surface layer with smaller pores and inner parts with larger pores. The surface layer and closed pores controlled water absorption. As the expanding agent fraction and the sintering temperature increased, the porosity and pore size increased. The porous materials with $Fe_2O_3$ and graphite as the expanding agents had a low absorption ratio of about 3% or lower while the porous material with $CaCO_3$ as the expanding agent had a higher absorption ratio and more open pores.

Recently, prepackaged-type surface preparation materials using redispersible polymer powders are widely used for interior and exterior finishing in the construction work. The purpose of this study is to evaluate the performance and the quality of prepackaged-type surface preparation materials using a VA/E/MMA terpolymer powder. Surface preparation materials using a VA/E/MMA terpolymer powder were prepared with shrinkage reducing agent contents of 0, 4 % and cellulose fiber contents of 0, 0.5, 1.0 %, and tested for drying shrinkage, strengths, adhesion in tension, crack and impact resistance, water absorption, permeability. As a result, prepackaged-type surface preparation materials show outstanding performance depending on the shrinkage reducing agent and cellulose fiber contents.

In modern days when architectural materials have grave impacts on overall design expression, materials for architecture, modern architecture into the service facility for business, education, religion, cultural assembly and residence, and evaluates each finishing material mainly used in exterior, lobbies and entrances of the building since the 1970's. When being applied social images into firstly selected materials, the scopes for material selection will be more narrowed down in more practical way. High tensity materials are suitable for public and active space and low tensity are for private and static area. This principle enables us to use architectural materials as one of the important elements which express the whole characteristics of the area.

The indoor air quality of new apartment buildings, which is known to cause sick housing syndrome, has become a major concern among apartment residents as well as construction companies in Korea. In this study, the effects of environmentally friendly materials and ventilation system are evaluated to compare the strategies applied to improve indoor air quality at the pre-occupancy stage. Six residential units are tested under three conditions : one unit is consisted of environmentally friendly materials and ventilation system, another unit is consisted of environmentally friendly materials and non-ventilation system, and the other four units are consisted of common materials and non-ventilation system.

Insulation in buildings are one of the crucial factors for energy reduction, and depending on the application areas and properties of the insulation requirements, various different types of insulation materials are being developed, produced, and used. Amongst these is the aircaps often used as packing materials. Because of their porous nature, they are highly efficient in preventing heat and are consequently used overseas often as insulation materials and as part of cold water concrete insulation curing method. This paper studies the recently developed usage of aircaps in waterproofing materials and evaluated their performance as supplementary insulation materials.

외장재에 대한 기존의 연구는 디자인 측면에서 계획적인 접근이 많아 외장재의 성능보다 외장재의 색채나 질감 등에 초점을 맞춘 연구가 많았으며 용도에 따른 공학적인 접근에서는 환경과 설비, 화재 구조 등 일반적인 연구 주제들에 국한되어 건물 유형에 적합한 외장재 선정과 성능제시에 관한 연구는 많지 않았다. 물론 최근 환경에 대한 관심이 높아지면서 친환경적인 관점에서 건축물 외장재의 연구가 이루어지고는 있으나 친환경적인 외장재 선택에 대한 실무적인 관점에서의 연구는 초보적인 단계이다. 따라서 본 연구에서는 최근 10여 년간 국내에서 사용된 외장재에 대한 사용 현황을 분석하고 건물용도별 외장재의 특성과 친환경적인 요소를 도출하여 향후 국내 건설업체 및 설계사무소 등이 친환경적이면서 성능이 적합한 외장재를 선택할 수 있도록 기본적인 정보를 제공하고자 하였다. 외장재 사용현황은 정량적인 빈도수 분석, 친환경 성능은 복합적인(정성+정량) 분석을 통하여 이루어 졌다. 조사된 건물의 외장재종류 개수의 평균은 2.59개로 나타났으며 유리, 금속, 석재, 수지, 시멘트, 목재, 점토 순서로 많이 사용되고 있었다. 4개의 친환경 외장재 특성에 의거하여 5종류의 고친환경재료를 선정하였으며 8가지 친환경적인 요소를 제시하였다.

Although the clays were one of the major materials of building constructions, presently, its functions are lesser and the cements take its place as building materials. however, the IAQ problems such as $CO_2$ increase, Rn gas and VOCs occurrence should be imperative from production and construction processes of the cements. This study aims to develop the alternate clay compounds to cements and analyze its properties by experimental tests. For the study, the claymineral of Chungchong-bukdo 10 areas are used. The chemical and structural properties are experimentally analyzed and the pozzolan reaction possibilities of clays are executed.

Despite of its advantange on shortening framework period of a super-tall building, gangform is prone to high safety risk due to its heavy weight during operation. Thus, this study is conducted to investigate the applicability of a lightweight gangform made of engineering composite materials. Compared to the conventional gangform, the proposed gangform showed greater performance not only in reduction of safety accidents on-site, but also in constructability and environmental aspects. The results of this study are expected to be served as the basis for developing the lightweight gangform in future.

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.

Hazardous chemicals emitted from building materials and furniture have led to social problems such as sick house syndrome. Test methods for the evaluation of pollutant emissions from furniture-like products have been applied using various national and international standards and classifications, but they are not currently unified. This research has been done to organize the various standards and certification methods and to make new classification systems. Proper test methods have been proposed, tested, and analyzed through this research.
