Special anti-erosion preservative for composite marine concrete and preparation method of special anti-erosion preservative
The invention relates to the technical field of marine corrosion prevention, in particular to a special anti-erosion preservative for composite marine concrete and a preparation method of the special anti-erosion preservative. The invention relates to a special anti-erosion preservative for composite marine concrete. The special anti-erosion preservative is prepared from the following raw materials in parts by mass: 16-20 parts of nano silicon powder, 3-5 parts of nitrite, 20 parts of calcium salt, 25-29 parts of coal ash, 13-15 parts of composite organic matter ash, 0.8 part of polycarboxylic acid, 0.2 part of sodium gluconate and 14-18 parts of superfine mineral powder. The anti-erosion preservative is obtained by mixing nano silicon powder, nitrite, calcium salt, coal ash, composite organic matter ash, polycarboxylic acid, sodium gluconate and superfine mineral powder according to a proper proportion. When the marine concrete is prepared, the anti-erosion preservative is added into the concrete according to a certain proportion, so that the compressive strength and breaking strength of the marine concrete can be improved, meanwhile, the erosion of chloride ions in the marine environment can be improved, the preparation process is simple, and the anti-erosion preservative has important application value for promoting the construction of infrastructures in the marine environment.
本发明涉及海洋防腐技术领域，具体涉及一种复合型海工混凝土专用抗侵蚀防腐剂及其制备方法。一种复合型海工混凝土专用抗侵蚀防腐剂，按质量份计由以下原料制备而成：16‑20份纳米硅粉、3‑5份亚硝酸盐、20份钙盐、25‑29份煤灰、13‑15份复合有机物灰分、0.8份聚羧酸、0.2份葡萄糖酸钠、14‑18份超细矿物粉。本发明将纳米硅粉、亚硝酸盐、钙盐、煤灰、复合有机物灰分、聚羧酸、葡萄糖酸钠和超细矿物粉以适当的比例混合得到抗侵蚀防腐剂。在制作海工混凝土时以一定比例加入上述抗侵蚀防腐剂添加到混凝土中，能够提高海工混凝土的抗压强度和抗折强度，同时能够改善海洋环境中氯离子的侵蚀，制备工艺简单，对促进海洋环境基础设施建设具有重要应用价值。
