FIBER REINFORCED CONCRETE AND MANUFACTURE METHOD THEREOF

摘要

PURPOSE: A fiber reinforcement concrete and a manufacturing method thereof are provided to solve the phenomena of a fiber ball and a cement ball generated from a conventional fiber reinforcement concrete and to improve production ability by reducing mixing hours. CONSTITUTION: A manufacturing method of a fiber reinforcement concrete is composed of the following steps of: the step(ST11) of a first input wherein a fine aggregate(As), a thick aggregate(Ab), and a fiber reinforcement are input into a mixer or a batcher plant; the step(ST12) of a first mixing wherein the fine aggregate(As), the thick aggregate(Ab), and the fiber reinforcement input into the mixer or the batcher plant are mixed for five to fifteen seconds at the first input step; the step(ST13) of a second input wherein cement(Ce) and a admixture(Am) are input to a first mixture mixed at the first mixing step; the step(ST14) of a second mixing wherein the cement(Ce) and the admixture(Am) input into the mixer or the batcher plant are mixed with the first mixture for five to fifteen seconds at the second input step; the step(ST15) of a third input wherein water(W) and an admixture(Ag) are input to a second mixture mixed at the second mixing step; the step(ST16) of a third mixing wherein the water(W) and the admixture(Ag) input to the mixer and the batcher plant are mixed with the second mixture for ten to twelve seconds; and the step(ST17) of discharging wherein the final mixture mixed at the third mixing step is discharged from the mixer or the batcher.
