This study aimed at developing polyethylene fiber-reinforced concrete (PEFRC) with high flexural toughness and sufficient slump for precast concrete. Experimental investigations were conducted regarding influences of mix proportion of matrix, fiber volume fraction, and shape of short fiber on slump and various mechanical characteristics of the PEFRC. As a result, PEFRC with more than 40kN・mm in flexural toughness and 10cm in slump could be derived, due to applying high-fluidity matrix and loosely bundled short fiber to the PEFRC. Moreover, it was shown that the PEFRC possessed generally good mechanical characteristics and durability as compared with steel fiber-reinforced concrete and plain concrete, respectively.
