A Study on the Physical Properties of Cement Composites with High-strength Vinylon Fibers

고강도 비닐론 섬유로 보강된 빛 투과 콘크리트의 투명 봉 간격 변화에 따른 물리적 특성 연구

LEFC(Light Emotion Friendly Conceret) was developed in Korea with demands of esthentic requirements in line with the recent developmental trend of concrete technology. The LEFC is made by inserting transparent transparent rods, and this forms a heterogeneous structure in the concrete matrix causing the LEFC substrate to crack due low adhesion between the rod and the cement. In this study, as a way to strengthen the bonding to the rod inserted in the LEFC, high strength vinylon fibers of varying mixture ratios were applied and physical properties were tested accordingly. To study the effect of different spacing of the bars on the LEFC, physical property testing was conducted on respective specimens with two different diameters (5mm, 10mm) inserted in different intervals of spacing (10mm, 15mm, and 20mm).
