In previous experiment, W/C was 50%, mixing ratio of BF (outer percentage based on the mass of mortar) was 0, 1, 3 and 5%. According to the observation of the fractured section of mortar, every BF slipped out without being cut, which means that the adhesion of BF and mortar was not enough and the primary tensile strength of BF was not shown. The compressive strength and bending strength of BF mortar was obtained in accordance with "Cement Strength Test" to confirm the strength improvement effect by BF. Authors has made short bamboo fiber (see Photo 1, BF for shot) by ourselves from Moso-bamboo, and it is the final purpose to develop the concrete for pavement which matrix is reinforced by this BF.
