FRP pipe alkali-activated slag-based seawater coral aggregate concrete column and preparation method thereof
The invention provides an FRP pipe alkali-activated slag-based seawater coral aggregate concrete column and a preparation method thereof. The FRP pipe alkali-activated slag-based seawater coral aggregate concrete column comprises an outer FRP pipe, an embedded FRP stirrup and an FRP longitudinal bar, and the FRP pipe is filled with alkali-activated slag-based seawater coral aggregate concrete. According to the alkali-activated slag-based seawater coral aggregate concrete, specific seawater and waste coral in open sea island reef areas are fully utilized as raw materials, and alkali-activated slag slurry with a compact slurry structure and good durability is taken as a cementing material, so that the bottleneck problems of low strength, insufficient durability and the like of traditional coral aggregate concrete are solved. Meanwhile, the corrosion-resistant FRP pipe confined concrete is adopted, so that the coral aggregate concrete is in a three-way stress state, and the bearing capacity, the ductility and the anti-seismic property of the coral aggregate concrete member can be effectively improved. The high-durability alkali-activated cementing material and the corrosion-resistant FRP are high combined, so that the FRP pipe alkali-activated slag-based seawater coral aggregate concrete column has the advantages of effective utilization of resources, greenness, environmental protection and the like.
本发明提出了一种FRP管碱激发矿渣基海水珊瑚骨料混凝土柱及制备方法，该混凝土柱包括外层的FRP管、内嵌FRP箍筋和FRP纵筋，FRP管内填充碱激发矿渣基海水珊瑚骨料混凝土。碱激发矿渣基海水珊瑚骨料混凝土充分利用远海岛礁地区特有的海水和废弃的珊瑚作为原材料，以浆体结构致密、耐久性良好的碱激发矿渣浆体作为胶凝材料来改善传统珊瑚骨料混凝土强度低、耐久性不足等瓶颈问题。同时采用耐腐蚀的FRP管约束混凝土，使珊瑚骨料混凝土处于三向受力状态，能有效提高珊瑚骨料混凝土构件的承载能力、延性以及抗震性能。本发明通过采用高耐久的碱激发胶凝材料与耐腐蚀的FRP“强强结合”，实现了资源有效利用及具备绿色环保等优点。
