摘要：合成了一种丙烯酸-环氧树脂涂层，研究了海水浸泡条件下涂覆丙烯酸-环氧涂层混凝土的力学性能、耐久性能，并对其水化产物及微观结构进行了分析。结果表明：在海水浸泡条件下，相较于无涂层对照组，涂覆丙烯酸-环氧树脂涂层的混凝土抗压、劈裂抗拉强度均相对较高，表面pH值减小幅度较小，抗氯离子渗透性能较好，可以保持混凝土内部的高碱性，水化产物中水化硅酸钙含量相对较高，基体结构致密，孔隙和微裂纹较少。涂覆丙烯酸-环氧树脂涂层可使海工混凝土具有优异的力学性能和耐久性能。 Abstract: A acrylic epoxy-resin coating was synthesized, and the mechanical and durability properties of concrete coated with acrylic epoxy-resin coating under seawater immersion conditions were studied. The hydration products and microstructure of the concrete were analyzed. The results show that under seawater immersion conditions, compared with the uncoated control group, the concrete with acrylic epoxy-resin coating has relatively higher compressive and splitting tensile strength, smaller reduction in surface pH value, better resistance to chloride ion penetration, and can maintain high alkalinity inside the concrete. The content of hydrated calcium silicate in the hydration product is relatively high, the matrix structure is dense, and there are fewer pores and microcracks. The marine concrete coated with acrylic epoxy-resin coating has excellent mechanical and durability properties.
