Confined concrete column based on TRC prefabricated shell made of sea sand and seawater and preparation method
The invention discloses a confined concrete column based on a TRC prefabricated shell made of sea sand and seawater and a preparation method. The confined concrete column comprises the TRC prefabricated shell and a core concrete column poured inside the TRC prefabricated shell, wherein the TRC prefabricated shell comprises a corrosion-resistant lining and a TRC composite material bonded to the periphery of the corrosion-resistant lining; the TRC composite material comprises fine aggregate concrete and at least one layer of fiber woven mesh pre-buried in the fine aggregate concrete; the fine aggregate concrete is made of the sea sand, the seawater, cement and the like; a plurality of hollow grouting holes are formed in the surface of the corrosion-resistant lining, and the interior of eachhollow grouting hole is filled with the fine aggregate concrete; and the core concrete column is made of seaside gravel, the sea sand, the seawater and the cement. According to the confined concrete column, all the composition materials are resistant to marine corrosion environment, the main raw material can be drawn locally, and construction is convenient, green and environmentally friendly; andthe TRC prefabricated shell can serve as a pouring formwork of the core concrete column and generates a confinement effect on the core concrete column, and therefore the total axial compression bearing capacity is improved.
本发明公开了一种基于海砂海水TRC预制外壳的约束混凝土柱及制备方法，包括TRC预制外壳和浇筑在TRC预制外壳内的核心混凝土柱；TRC预制外壳包括耐腐蚀内衬和粘接在耐腐蚀内衬外周的TRC复合材料；TRC复合材料包括细骨料混凝土和预埋在细骨料混凝土中的至少一层纤维编织网；细骨料混凝土采用海砂、海水和水泥等制成；耐腐蚀内衬的表面均开设有若干个镂空灌浆孔，每个镂空灌浆孔内均充填有细骨料混凝土；核心混凝土柱采用海边碎石、海砂、海水和水泥制成。本发明中所有组成材料均耐海洋腐蚀环境，主要原料可以就地取材，且施工便利、绿色环保。TRC预制外壳既能充当核心混凝土柱的浇筑模板，又对其产生约束作用，从而提高总轴压承载力。
