Salt-corrosion-resistant admixture for marine concrete and preparation method of salt-corrosion-resistant admixture
The invention discloses a salt-corrosion-resistant admixture for marine concrete and a preparation method of the salt-corrosion-resistant admixture, and belongs to the technical field of concrete admixtures. The corrosion-resistant seepage-proofing coating is prepared from the following raw materials in parts by weight: 40 to 60 parts of a corrosion inhibitor, 20 to 30 parts of a seepage-proofing agent, 60 to 80 parts of mineral micro powder, 0.5 to 1 part of filler, 1 to 3 parts of a corrosion-resistant auxiliary agent and 0.3 to 0.5 part of a water reducing agent. Through the combined action of various raw materials, on one hand, from the aspect of improving the density of the concrete, various raw materials are blended for use, so that the working performance of the concrete and the internal compactness of the concrete can be remarkably improved; on the other hand, part of inhibitor materials are added from the perspective of physical and chemical reactions, so that the erosion reaction can be reduced, the capability of the marine concrete for resisting chloride ions, sulfate ions and other salt harmful ions in seawater from entering the concrete is improved, the damage to marine concrete test pieces is reduced, and the service life of the marine concrete is prolonged. The marine concrete has relatively high early and later strength and excellent durability.
本发明公开了一种海工混凝土用抗盐类侵蚀外加剂及其制备方法，属于混凝土外加剂技术领域。它是由以下重量份的原料组成：抗蚀剂40‑60份、防渗剂20‑30份、矿物微粉60‑80份、填料0.5‑1份、抗蚀助剂1‑3份、减水剂0.3‑0.5份。本发明通过多种原料共同作用，一方面从提高混凝土致密度的角度，多种原料掺合使用，可显著提高混凝土的工作性能及混凝土的内部密实度；另一方面还从物理化学反应的角度添加部分抑制剂材料，可以减少侵蚀反应的发生，从而提高了海工混凝土抵抗氯离子、硫酸根离子等海水中盐类有害离子进入混凝土内部的能力，减少对海工混凝土试件的破坏，使海工混凝土具有较高的早期、后期强度和优良的耐久性能。
