Fiber-reinforced concrete.

摘要

A fiber-reinforced concrete comprising a concrete matrix including two kinds of short fibers (A,B) one being a short fiber (A) having a Young's modulus higher than that of concrete, the other being a short fiber (B) which has a Young's modulus lower than that of concrete a showing good adhesiveness to concrete. The said fibers are mixed in a predetermined ratio and are dispersed in the concrete matrix. A reinforcing material for concrete is also dislcosed, such material consisting of a mixture of the fibers (A.B) as mentioned above.
