The invention discloses a reinforced concrete material suitable for ocean coral island. The reinforced concrete material comprises rebar and concrete, wherein the concrete contains the following raw materials: a corrosion inhibitor accounts for 0.1-0.5% of the cement mass; the mass ratio of the cement to coral sand aggregate is (1:3)-(1:4); and the water-cement ratio is (2:5)-(3:5). For the reinforced concrete material disclosed by the invention, in combination with the characteristics of ocean coral island, the materials are obtained nearby, and the seawater is directly mixed for maintenance; by adopting coral sand as coarse aggregate and fine aggregate, the quantity demand for the building raw materials transported from the mainland is reduced, the transport cost is lowered, the island construction cost is saved, and the island construction is accelerated; by adopting 2205 duplex stainless steel with excellent corrosion resistance as reinforcement and combining a corrosion inhibitor taking aluminum tripolyphosphate as a main agent, the corrosion resistance of the stainless steel rebar is further enhanced, the service life of the reinforced concrete material is prolonged, later maintenance is convenient, and the maintenance cost is low.
