Compression-resistant and corrosion-resistant concrete material for ocean engineering and preparation method of compression-resistant and corrosion-resistant concrete material
The invention discloses a compression-resistant and corrosion-resistant concrete material for ocean engineering and a preparation method of the compression-resistant and corrosion-resistant concrete material. The material comprises a solid waste-based cementing material, coarse aggregate, fine aggregate, sulfate-resistant cement, ceramsite, broken glass slag, slag powder, nano silicon dioxide, asphalt, steel fibers, alkali-resistant glass fibers, an expanding agent, a concrete preservative, a silane dipping coating, a metal antirust agent, a scale and corrosion inhibitor, a thickening agent, a defoaming agent and a proper amount of water. According to the method, the solid waste-based cementing material prepared from the solid wastes such as alkaline residues, red mud, carbide slag and ardealite is applied to the concrete and has the properties of high strength, low expansion rate, excellent sulfate resistance and low chloride ion permeability, the wastes are reused, the production cost of the concrete is reduced, and the overall performance of the concrete is also improved; and the steel fibers, the alkali-resistant glass fibers and the broken glass slag are combined with the concrete, so that the cohesiveness of the concrete is improved, and the compressive strength and the impact resistance of the concrete can also be improved.
本发明公开了一种抗压耐腐蚀的海洋工程用混凝土材料及其制备方法，包括固废基胶凝材料、粗骨料、细骨料、抗硫酸盐水泥、陶粒、玻璃碎渣、矿渣粉、纳米二氧化硅、沥青、钢纤维、耐碱玻璃纤维、膨胀剂、混凝土防腐剂、硅烷浸渍涂料、金属防锈剂、阻垢缓蚀剂、增稠剂、消泡剂和适量的水。本方法利用碱渣、赤泥、电石渣、磷石膏等固体废弃物制备的固废基胶凝材料应用在混凝土中具有强度高、膨胀率低，抗硫酸盐性能优异、氯离子渗透率低的性能，让废物再次利用，降低混凝土的生产成本，也提高混凝土的整体性能；利用钢纤维、耐碱玻璃纤维和玻璃碎渣与混凝土结合，不仅提高混凝土的粘聚性，而且还能增加混凝土的抗压强度和抗冲击性能。
