Abstract: Provided is a high-strength and high-performance permeable concrete using low-grade iron ore, which recycles waste resources, saves natural aggregates, preserves environment, and has improved strength and resistance against freezing and thawing. The high-strength and high-performance permeable concrete using low-grade iron ore is obtained by mixing low-grade iron ore of 1470-1680kgf/m^3 having a particle size of 5-13mm, water of 150-180kgf/m^3, cement of 540-650kgf/m^3, a high-performance water-reducing agent of 0.65-2.7kgf/m^3, and admixtures of 60-72kgf/m^3 and has a slump less than 2.5cm, a strength of 210kgf/cm^2 or more, and a permeability coefficient of 0.1cm/sec or more.
