최근 $CO_2$ 배출의 저감을 위한 활동으로 시멘트의 사용량을 줄이고, 고로슬래그 및 플라이 애시 등과 같은 산업부산물을 적극 활용하여 건설분야에 적용하고자 하는 움직임이 활발하게 진행되고 있으며, 이를 통해 환경부하저감 및 자원재활용을 도모하고 있다. 이에 본 연구에서는 자원재이용 및 환경부하저감을 위한 기초적 연구로서 고로슬래그 및 플라이 애시를 사용하여 부산물의 치환율에 따른 경화성상 및 내구성상을 비교 분석하고 고로슬래그와 플라이애시의 3성분계를 치환한 콘크리트 성상을 검토함으로서 결합재로서의 상성관계를 평가하여 향후, 대량활용을 위한 기초자료를 제시하고자 하였다. 고로슬래그 미분말 및 플라이애시를 대체한 콘크리트의 압축강도는 재령 7일 초기강도에서는 무혼입 콘크리트에 비해 현저히 낮은 수준으로 발현하고 있으나, 28일 이후에는 무혼입 콘크리트에 비해 유사하거나 높은 압축강도를 발현하였다. 또한 고로슬래그 미분말의 대체율이 증가함에 따라 염해 저항성이 향상되는 것으로 나타났으며, 이는 기존 연구결과에 따라 고로슬래그 미분말에 의해 염화물 이온이 콘크리트 표면에 고정화됨으로서 염해 저항성이 향상되는 것으로 판단된다. Recently, reducing usage of cement and using by-product of industry such as blast furnace slag and fly-ash have been increased to reduce $CO_2$ gas emission. That apply to construction. As a result, reduction of environmental stress and recycling of resources are expected. In this study, as basic study to the reuse of resources and reduce Environmental Load, comparing and analyzing hardening characteristics and durability as using the blast furnace slag and fly-ash, examining concrete characteristics substituted the three elements for the blast furnace slag and fly-ash and evaluating the relationship as binder. Through this, it want to provide the basic data for mass utilization. Blast furnace slag powder and replaced at fly-ash compressive strength of concrete in the strength of the initial seven days material age lower level of expression significantly compared to the concrete, but, 28 days after the similar or higher compressive strength than the concrete expression of the was. In addition, the reserves replacement of blast furnace slag powder salt injury increasing resistance are seen improvements, according to the conventional blast furnace slag powder study by the chloride ions on the surface of the concrete are improved being fixation salt injury resistance is considered.

김규용,양현석,박영필,Kim, Kyu-Young,Yang, Hyun-seok,Park, Young-Pil 대한기계학회 1996 大韓機械學會論文集A Vol.20 No.10

Recently, the high-precision vibration attenuation technology becomes the essence fo the seccessful development of high-integrated and ultra-precision industries, and is expected to continue playing a key role in the enhancement of manufacturing technology. Vibration isolation system using an air-spring is widely employed owing to its excellent isolation characteristics in a wide frequency range. It has, however, some drawbacks such as low-stiffness and low-damping features and can be easily excited by exogenous disturbances, and then vibration of table is remained for a long time. Consequently, the need for active vibration control for an air-spring vibration isolation system becomes inevitable. Furthermore, for an air-spring isolation table to be successfully employed in a variety of manufacturing sites, it should have a guaranteed robust performance not only to exogenous disturbances but also to uncertainties due to various equipments which might be put on the table. In this study, an active vibration suppression control system using H.inf. theory is designed and experiments are performed to verify its robust performance. An air-spring vibration isolation table with voice-coil-motors as its actuators is designed and built. The table is modeled as 3 degree-of-freedom system. An active control system is designed based on $H_\infty$control theory using frequency-shaped weighting functions. Analysis on its performance and frequency responce properties are done through numerical simulations. Robust characteristics of$H_\infty$ control on disturbances and model uncertainties are experimentally verified through (i) the transient response to the impact excitation of the table, (ii) the steady-state response to the harmonic excitation, and (iii) the response to the mass change of the table itself. An LQG controller is also designed and its performance is compared with the $H_\infty$ controller.

김규용,민충식,이태규,미야우치 히로유키,박규연,이광준 한국건축시공학회 2011 한국건축시공학회지 Vol.11 No.4

High Strength Concrete (HSC) has weakness that in a fire, it is spalled and brittles. The phenomenon of spalling is made by water vapor's being confined in watertight concrete. This study is aimed to evaluate explosive spalling properties of high strength concrete with □100×100×200 mm specimen and □400×400×1500 mm column. To prevent spalling of concrete, fireproof coating and PP fiber are used. As a result, □400×400×1500 mm column was prevented spalling likes □100×100×200 mm specimen. When concrete protected failure to explosive spalling, quantity heat ratio (which fireproof coating specimen to pp fiber mixed specimen) between □100×100×200 mm and □400×400×1500 mm was maximum value at 20 minute, but difference of quantity heat ratio decreased and quantity heat ratio of each specimen is almost same at 30 minute.

김규용,양승훈 濟州大學校 師範大學 科學敎育硏究所 1997 科學敎育 Vol.14 No.-

We suggest the possibility of "historical teaching" as an effective strategy for teaching science in classroom. At first, we survey the historical background for historical teaching of science, and then present the possible merits of introducing the history of science into science class: (1) to overcome the misconceptions of students in science; ( 2 ) to bridge science and other disciplines; ( 3 ) to understand the social aspects of science; (4) to understand the nature of science and scientific method, etc. Finally, we present briefly the some limits of historical teaching.

고온 및 하중 재하조건을 고려한 콘크리트의 역학적 특성 평가

김규용,이태규,민충식,이계혁,남정수,김영선,Kim, Gyu-Yong,Lee, Tae-Gyu,Min, Choong-Siek,Lee, Kye-Hyouk,Nam, Jeong-Soo,Kim, Young-Sun 대한건축학회 2011 대한건축학회논문집 Vol.27 No.3

It was experimentally investigated in effects of high temperature and loading condition on the mechanical properties of concrete. This study is aimed to study the effect of elevated temperatures on mechanical properties of concrete according to compressive strength under loading. Tests were conducted on ${\O}100{\times}200mm$ cylinder specimens, which were tested under both stressed and unstressed conditions by steady-state test. The specimens were under-loaded to 0, 20, 40 percent of their ultimate compressive strength at room temperature and subjected to temperatures ranging from 100 to $700^{\circ}C$, and the residual compressive strength compared to that observed at $20^{\circ}C$. As a result, effect of mechanical properties of concrete at elevated temperature was especially subjected to transient creep more than thermal strain under loading in case of over $500^{\circ}C$.
