콘크리트 충전형 합성강관기둥의 현장실용화에 앞서 고강도측면과 초유동측면을 동시에 만족해야 하는 420 및 $560kg/cm^2$강도의 고강도-초유동 콘크리트의 최적배합비 도출을 위한 실내시험을 수행하고 그 결과를 바탕으로 레미콘공장에서의 콘크리트 생산에 다른 문제점 해결, 현장까지의 운반에 따른 경시변화등을 검토하기 위하여 실물크기의 강관기둥을 제작하여 현장실물모형시험을 실시하였다. 또한 현장적용시점이 동절기임을 고려하여 콘크리트의 경화지연에 대비한 연구의 필요성으로 인해 응결시간, 내부수화온도이력 및 초기강도의 발현정도에 관한 추가모형실험을 실시하여 현장적용에 적함한 고품질의 고강도-초유동 콘크리트를 얻고자 하였다.

This paper is to report the results of mock-up test for concrete during severe cold weather. The temperature is fixed at -20℃. The mock-up specimens were fabricated simulating slab, wall and column. Heating coil with different heat capacity with 5 W and 15 W were embedded at slab specimen. Test results revealed that at -20℃, temperature dropped below 0℃ since around 70 hours. It takes 7 days to gain 45°D·D of maturity for avoiding frost damage at early age.

Available daylight in inside offers comfortable view environment, and psychological and physical advantages to people in the room. But, it has a problem of an excessive direct sunlight. This study calculated daylight responsive dimming control slope by Roller Shade system with Mock-up test. With three 1/2 scale Mock-up rooms, we performed a test for calculation of daylight responsive dimming control slope in different shade height of each room through the different height of roller shade systems. This research will be used as a fundamental study for automated roller shade systems.

The techniques related to ultra-high strength concrete(UHSC) became the key issue in recent days since requirements of the high-rise building which story is over than 100 gradually increases. Therefore, for the development of 150MPa UHSC this research is generally categorized by 4 parts: development of pre-mixed binders, evaluation for the fire performance of coarse aggregate, optimization of the mixture proportion, and mock-up test. Finally, based on the optimized mixture and its laboratory tests, mock-up test for wall and column specimens were carried out to simulate and evaluate the UHSC in real situation. The mechanical properties of core specimens were compared with the cylinder specimens made in laboratory. For instance, it showed the reasonable the results that the strength at the age of 91 days is 183MPa.

This study is concerned with the root penetration resistance competence and constructability of a waterproofing and root penetration resistance layer of an eco-bridge which is applied with various types of seeding. For the review of root penetration resistance competence, the competence was tested using herbs, woody plants, and tall trees. As a result, there was no tear of or damage to the waterproofing and root penetration resistance layer as well as the sweeping-down phenomenon of a waterproofing and root penetration resistance layer by soil. Also, the effect of the root growth of herbs, woody plants, and tall trees on the root penetration resistance system was confirmed.

Recent construction method in mass concrete structures would depend on the control of hydration heats and thermal stresses by using the low heat cement, optimized block size and a lift height, or both. This experimental study aims at the possibility of thermal cracks according to the different types of cementations material and at the investigation of these effects. Four different types of cements are applied to the mock-up test and are evaluated in terms of temperature rises and thermal stresses with the use of thermocouples, strain gauges and effective stress gauges. As a result of this study, it was found that stresses measured from effective stress gauges agree well with ones form strain gauges, and the trend of stress occurrence can be well evaluated from theoretical analysis.

The waterproofing material can be roughly divided into a coating material and a sheet waterproofing material. In the case of coating waterproofing materials, sheet waterproofing materials, which are easy to use in terms of workability and quality control, have been recently used because of their incomplete use of coating thickness, long curing time and poor blending due to in situ blending. However, in the case of the sheet waterproofing material, since the sheet overlapping portion is inevitably generated, various defects (breakage due to the behavior) are frequently observed. Therefore, it is imperative to establish fundamental measures to minimize this.
