The ocean underwater concrete column structurally comprises an RPC composite material shell, a core concrete column is poured in the RPC composite material shell, and spiral stirrups are buried in the core concrete column; the RPC composite material is a mixture of RPC and hollow microspheres according to a mass ratio of 100: (0.1-5), the particle size of the hollow microspheres is 20-50 [mu] m, and the hollow microspheres are selected from one or a combination of more than two of carbon hollow microspheres, silicon dioxide hollow microspheres and ceramic hollow microspheres. A pouring material of the core concrete column is a cementing material containing carbon hollow microspheres and circulating fluidized bed fly ash. The hollow microspheres are creatively added into the shell and the core material of the underwater concrete column, so that the mechanical property of the concrete column can be improved, and the corrosion resistance of the concrete column can be enhanced.
本发明公开一种海洋入水混凝土柱，所述海洋入水混凝土柱结构包括RPC复合材料外壳，在RPC复合材料外壳内部浇筑核心混凝土柱，核心混凝土柱内埋有螺旋箍筋；所述RPC复合材料是RPC和中空微球按照100：(0.1‑5)质量比的混合物，所述中空微球粒径为20‑50μm，选自碳中空微球、二氧化硅中空微球、陶瓷中空微球中的一种或两种以上的组合。所述核心混凝土柱的浇筑材料是包含碳中空微球和循环流化床粉煤灰的胶凝材料。本发明创造性的在入水混凝土柱外壳和核心材料中加入空心微球不仅能提高混凝土柱的力学性能，而且能增强其耐腐蚀性能。
