CONCRETE USING RECYCLED AGGREGATES BY REINFORCING WITH STEEL-FIBERS

摘要

PURPOSE: A reinforced steel fiber-based recycled aggregate concrete composition is provided to prevent the intensity reduction of concrete due to the use of recycled aggregate by reinforcing the recycled aggregate with steel fiber. CONSTITUTION: A reinforced steel fiber-based recycled aggregate concrete composition includes steel fiber and concrete containing cement, sand, and aggregated with recycled aggregate. The steel fiber is mixed with the concrete to reinforce the intensity of the concrete. The content of the steel fiber is 0.5-1.0 volume% of the volume of the mixture containing the concrete and water. The content of the recycled aggregate is 30-100 volume% of the entire aggregate. The concrete further includes silica fume.
