Light Emotion Friendly Concrete (LEFC) transmits light through plastic rods inserted in concrete to stimulate emotion and give new image to space. There is a characteristic that can give a diverse and sensuous feeling depending on the change of the diameter and the interval of the plastic. For the application in the field, it is necessary to analyze the mechanical characteristics according to the case. In this study, we investigate the change of the mechanical properties of the light transmitting concrete reinforced with PVA fiber according to the change of the diameter (5mm, 10mm) and spacing (10mm, 15mm, 20mm) of the plastic rod.
