RECYCLING FIBER REINFORCED CONCRETE AND MANUFACTURE METHOD THEREOF
The present invention relates to recycled fiber reinforced concrete using recycled plastic fiber, which comprises: concrete mixed by a predetermined mixing ratio; and a recycled plastic fiber reinforcing material added to the concrete, wherein the recycled plastic fiber reinforcing material is formed in a specific gravity of 0.80-0.92, a length of 15-30 mm, and a diameter of 0.6-1.3 mm, and is mixed by 0.5-2.5% compared to the volume of the concrete. In addition, the present invention relates to a method for manufacturing recycled fiber reinforced concrete using recycled plastic fiber, which comprises: an aggregate and cement injection step of injecting aggregate and cement; a dry mixing step of mixing materials for the injected aggregate and cement to be evenly mixed; a material injection step of injecting and mixing water and an admixture when the dry mixing step is completed; a primary mixing step of mixing the aggregate, cement, water and admixture when the material injection step is completed; a recycled plastic fiber injection step of injecting and mixing a recycled plastic fiber reinforcing material after the primary mixing step; and a second mixing step of additionally mixing the mixture after the recycled plastic fiber injection step is completed.
