This paper aims to quantitatively evaluate concrete quality factors according to the application of thermal insulated gang form. As a result of the experiment, it was found that the amount of calcium hydroxide produced increased in the insulated gang form than in the general gang form, and the thicker the insulation of the insulated gang form, the greater the amount of calcium hydroxide produced.

This paper examines the efficiency of the application of conventional and insulated gang forms for curing and protection of concrete by comparing the amount of electric energy required therefor. In addition, a thermal vision camera was used to identify heat loss from surfaces of the gang forms after each placement of concrete. Experimental results, show that the heat loss at the submerged temperature was large at the submerged surface due to the large calorific value at the surface of the mold. The insulated gang form had some heat loss in the horizontal bars. In the case of adiabatic reforming, the pattern shows a constant calorific value over time. In conclusion, the insulation performance is better than that of general gang form.

This study examine Effect of Change of Compressive Strength of Concrete Members with Insulating Gang form on Temperature History of Concrete Positions. Test show, insulating gang forms differences and gang forms have 10℃ on peak point temperature of surface and Center if temperature history have 24Mpa by change of compressive strength. In addition, there have 14℃(16℃) on peak point temperature of surface and Center if temperature history have 40(60)Mpa. Therefore, insulating gang forms have an effect insulating performance.

본 논문은 동절기 콘크리트 보양 시 투입되는 에너지(전력) 소비량과 콘크리트 발열량 변화를 통해 단열갱폼의 단열성능을 검토하고자 하였다. 실험결과에 따르면, 일반갱폼은 콘크리트 타설 이후 12시간동안 에너지(전력) 소비가 3회 발생하게 된다. 반면 단열갱폼은 콘크리트 타설 후 21시간 동안 에너지(전력) 소비가 발생되지 않았다. 최종 전력 소비량은 일반갱폼이 단열갱폼보다 3.7배 높게 나타나 에너지(전력) 소비에서 단열갱폼의 우수한 성능을 확인할 수 있었다. 발열량 검토결과는 일반갱폼에서 콘크리트 타설 후 외기 온도변화에 따라 발열량이 크게 변하는 것을 알 수 있었다. 하지만 단열갱폼의 경우 프레임 일부에서 미비한 열손실이 발생했을 뿐 콘크리트 타설 직후부터 거푸집 탈형까지 일정한 발열패턴을 보여주고 있었다.

Korean traditional houses have been developed in harmony with natural environment and comfortable indoor condition by using the natural resources including building layout, space composition and materials. Originally Korea traditional architectures have used wood lintel constructions and loess walls through the many years. Theses loess have many strength such as highly heat capacity, controling of humidity, a deodorant than any other materials. Nowaday it is recommended to use exterior and interior walls in loess wall to meet the eco-friendly materials to improve our residental environmental. Thus this study aims to research the sound insulation performance of traditional loess brick wall varied with thickness, thermal insulation materials and cavity wall. The sound insulation performance of these loess walls are compared with other masonry wall's and sound insulation performance of th walls were tested in anechoic laboratory to measure the sound transmission loss of these walls. The loess brick wall with 75mm thickness of cavity is shown the sound insulation performance with Rw 57 which is nearly same performances of 1B brick wall and cement 8' block wall, The improving effect of insulation materials is shown in the high frequency bandwidth. Especially, there is improving as much as 11 dB using the extruded poly stylene form(75mm) and poly ethylene film(0.7mm).

Recently energy management measures at the political level, for the purpose of reducing energy consumption in the building sector, are being actively introduced. As a practical method, the exterior insulation method, which is proven to effective in reducing the energy loss through walls, has been favored. In this study, detailed implementations are suggested to activate exterior insulation system which can improve the housing insulation performance. The newly designed Gang-form system with hanging scaffolding was suggested to revamp constructability for finishing outer wall. The research results are based on a multifaceted analysis of the current problems of exterior insulation systems, and on recommendations proposed by exterior insulation experts in the Charrette discussion. The study has indicates that the customized TACT schedule considering the site condition has shortened the construction period to 5 months from 7.5 months. Through utilizing the suggestions of this study, the prevalence of exterior insulation systems is expected to become widespread.

본 논문은 단열갱폼의 공동주택현장 적용을 통해 단열갱폼 동절기 보양우수성을 확인하고, 현장 적용에 따른 경제적 타당성을 분석하고 있다. 실험결과에 따르면 실제 보양투입 비용은 사전계획대비 약 5천 2백만 원을 절감하였으며, 기존 일반갱폼대비 약 1억 6천만 원을 절감하였다.(참고 - 변경전 갱폼 자재비는 2억 6천만 원에서 변경 후 3억 1천만 원으로 약 5천만 원 증가함) 결과적으로 단열갱폼으로 변경하여 약 1.1억 원 가량의 공사비를 절감할 수 있었다. 현장마다 층수, 동수, 면적이 달라짐에 따라 보양공사비가 변경될 수 있으니 단열갱폼 적용 예정인 현장에서는 사전에 충분한 검토가 이루어져야 할 것으로 판단된다.
