Abstract

See full text

Provided is a fiber reinforced cement based mixed material capable of securing high tensile strength and high toughness even after development of a crack. A fiber reinforced cement based mixed material contains cement, a mineral admixture, water, a chemical admixture, aggregate particles, and fibers, the aggregate particles contained in the fiber reinforced cement based mixed material in a proportion of 50 to 95% in terms of a weight ratio to the total weight of the cement and the mineral admixture, wherein a mean particle diameter of the aggregate particles is 0.2 to 0.8 mm, and at least some of the fibers is formed to be a bumpy fiber having asperities formed in the surface thereof, and a ratio (h/H) of a depth h of each of recessed portions among the asperities of the bumpy fiber to a smallest cross-sectional diameter H thereof is 0.05 to 0.8.
