기포제 적용 빛 감성 친화형 콘크리트의 휨 특성 예측 모델

Concrete, which is the most widely used building material in modern times, has been improved not only in strengthbut also in structural performance such as increase in toughness and ductility, weight reduction, and improvement inquality of human life. Due to the surge in demand for the building, there is a tendency to be used variously fromarchitectural panel and architecture to interior accessories. In Korea, a light-transmitting concrete, LEFC(LightEmotion Friendly Concrete), that insert plastic rods to stimulate emotional sensation through the combination of lightand concrete has developed. In previous research, it was confirmed that the use of a synthetic foam agent rather thanan animal foam agent did not cause a fogging phenomenon. In this study, lightweight by applying foaming agent toLEFC and two types of fiber (Nylon Fiber, Polyvinyl Alcohol) were compared to achieve to investigate the fiber tobe applied in future. An equation that can predict the loss and adhesion reduction of the concrete section accordingto the diameter of the rod (5mm, 10mm) and the interval (10mm, 15mm, 20mm) was proposed.
