Seawater and sea sand ultra-high performance concrete as well as preparation method and application thereof
The invention discloses seawater and sea sand ultra-high performance concrete as well as a preparation method and application thereof, and belongs to the technical field of building materials. The seawater and sea sand ultra-high-performance concrete comprises a cementing material, sea sand, seawater, basalt fiber bundles, nano sol and auxiliaries, wherein the auxiliaries comprise a high-performance water reducing agent, a defoaming agent, a retarder and a wetting agent. Seawater and sea sand are adopted as raw materials, on one hand, the problem of shortage of fresh water and common sand resources is solved, and on the other hand, expensive raw material transportation cost is saved for port engineering/maritime engineering structures; the seawater, the sea sand and the basalt fiber bundles cooperate with one another, corrosion of chloride ions and sulfate ions in the seawater and the sea sand to the fibers is avoided, and the compressive strength, the breaking strength and the permeability resistance of the seawater and sea sand ultra-high-performance concrete are further improved by cooperatively using specific auxiliaries.
本申请公开了一种海水、海砂超高性能混凝土及其制备方法与应用，属于建筑材料技术领域。该海水、海砂超高性能混凝土包括胶凝材料、海砂、海水、玄武岩纤维束、纳米溶胶和助剂，助剂包括高性能减水剂、消泡剂、缓凝剂和润湿剂。本申请采用海水海砂作为原料，一方面缓解淡水及普通砂资源短缺的问题，另一方面为港工/海工结构节省昂贵的原材料运输费用；海水、海砂与玄武岩纤维束配合作用，避免了海水海砂中的氯离子和硫酸根离子对纤维的腐蚀，配合使用特定的助剂，进一步提高海水、海砂超高性能混凝土的抗压强度、抗折强度和抗渗透性。
