As the building is becomes bigger and larger, it can lead to big damage in case of fire. Also, tunnel, machine room and underground joint are spaces that can cause high temperature fire above 1,350℃ in case of fire. Therefore, a refractory material is need that can be withstand in high temperatures for long time. One side, the composition of oyster shell is CaCO<sub>3</sub> of 90% or more. It is expected that it will be possible to use it as a high calcium natural material which is the material of the refractory board. According to, Study on bending, compressive strength of mortar according to temperature and heating time change using classified oyster shell as aggregate.

Curtain wall means a non-bearing wall that forms the outer walls of a building to divide the exterior and interior space. The increased use of curtain walls is diverse, including structural safety, watertightness, and wind pressure. As the government's energy conservation policy and the aim of zero-energy houses, the importance of heat reduction is also greatly increased. So, the study of monotony is constantly being conducted. Thus, in this study, insulation performance was analyzed through simulation according to the shape of curtain wall and the shape of insulation inside, and the purpose of this study was to provide basic data on the application of insulation criteria by energy saving design of buildings.

As energy related problems continue to arise, Korea’s thermal insulation market for the zero energy homes is also demanding major changes, but there are no realistic countermeasures. Also, interest in inorganic insulation is growing as damage from multifamily housing fire using flammable insulation materials is increasing. On the other hand, many studies have been conducted on lightweight foam concrete, which implies a sufficient possibility as an insulation material by generating a large amount of air bubbles. However, studies of existion bubble concrete are not quantified by the experimental difficulty of using bubbles when compared. Therefore, in this study, the change in strength due to air pressure using a bubble foam, one of the types of air bubbles for the development of light foam concrete.

The strength of cement mortar is one of the most important factors in design and construction. Strength can vary widely depending on factors such as water cement ratio, aggregate and materials and curing. In the study, it was found that the standardized method of making the cement mrtar was different from the standard method of preparing the cement mortar by the different process of the cement mortar. I wanted to know the difference. Experiments were carried out to investigate the differences in strength, physical properies and performance depending on the points when the sample were made long in vertical form.

There are about 3,500 people living in the Seoul Dosshouse, including Namdaemun, Dongdaemun, Donui-dong, Changshin-dong, and Yeongdeungpo. The daytime temperature in the Dosshouse is 43 degrees and the indoor temperature is 35 degrees, which is also higher than the surrouding area. Most of them live in one-person the poor strata, where they have been fighting the heat and the summer. The old building is closely located and a 1.5-pyeong room without windows is a hot environment. Water, air-conditioning is difficult or impossible for people who are economically inferior and cannot solve their own solutions. The solution that can be provided by the country is to heat up once or twice a day by fire hose or shelter. However, there are many patients with discomfort, the distance is far, and the effect is insignificant. Therefore, through this experiment by using discarded banner, I would like to suggest a way to solve the summere heat of the Dosshouse.

Curtain wall is constructed in various forms and designs by forming the exterior walls of a building, and refers to non-bearing walls that divide the exterior and interior spaces of a building. Curtain walls require not only wind pressure, but also waterproof, insulation, insulation, and durability, as well as the effects of recent frequent earthquakes. Studies on the sleeve used to connect the vertical member mullions in the process of high-rise curtain walls are insufficient. In this study, sleeves connecting curtain wall mullions were developed to absorb external displacement, and the purpose of this study was to evaluate economic feasibility through comparison with existing construction methods.

The development of insulation, the most important factor, is slow. The curtain wall market is getting bigger as the bulidings are getting bigger, but the insulation of the window is getting a problem. In order to solve this problem, we want to develop the insulation block used in the window frames. We will examine the insulation effect by using the existing Azon insulation block and the thermal worm convex which is to be developed with Therm 7.4 program.
