Method of mixing steel fiber reinforced concrete

摘要

A method of mixing a steel fiber reinforced concrete comprising the steps of subjecting steel fibers each having a surface to weight ratio of over 900 mm2/g to a pretreatment so as to orientate said steel fibers in a predetermined direction, randomly directing said orientated steel fibers through grating means having a grating space which is about two to four times the length of each of said steel fibers, and thereby introducing said steel fibers into components of a concrete or into an uncured concrete made up of the same.
