Marine concrete high-corrosion-resistance admixture and preparation method thereof
The invention provides a marine concrete high-corrosion-resistant admixture and a preparation method thereof. The marine concrete high-corrosion-resistant admixture is prepared from the following raw materials in parts by weight: 3-5 parts of a sulfate corrosion resistant material and 6-8 parts of a chloride ion corrosion resistant material. The chloride ion erosion resistant material comprises a high-dispersity modified calcium-aluminum-based material; the sulfate erosion resistant material comprises a capsule wall component of an ethyl cellulose membrane inlaid with barium alginate fibers and a capsule core component composed of nano silicon dioxide. The preparation method comprises the following steps: adding a nano silicon dioxide and barium nitrate mixed suspension into an ethyl cellulose modified sodium alginate solution, and reacting to obtain a sulfate erosion resistant material; reacting the zeolite molecular sieve, sodium hydroxide, aluminum hydroxide and calcium oxide to obtain a chloride ion erosion resistant material; the sulfate corrosion resistant material and the chloride ion corrosion resistant material are mixed according to the weight ratio of (3-5): (6-8) to prepare the marine concrete high-corrosion-resistant admixture.
本发明提供了一种海工混凝土高抗蚀外加剂及其制备方法，所述海工混凝土高抗蚀外加剂的制备原料按重量计包括如下组分：抗硫酸盐侵蚀材料3‑5份和抗氯离子侵蚀材料6‑8份。所述抗氯离子侵蚀材料包括高分散性改性钙铝基材料；所述抗硫酸盐侵蚀材料包括镶嵌海藻酸钡纤维的乙基纤维素膜的囊壁组分和纳米二氧化硅组成的囊芯组分；其制备方法包括：将纳米二氧化硅硝酸钡混合悬浮液加入乙基纤维素改性的海藻酸钠溶液反应得抗硫酸盐侵蚀材料；将沸石分子筛、氢氧化钠、氢氧化铝和氧化钙反应得抗氯离子侵蚀材料；将所述抗硫酸盐侵蚀材料和抗氯离子侵蚀材料按3‑5：6‑8的重量比混合后制得所述海工混凝土高抗蚀外加剂。
