C-F-S-H crystal nucleus early strength agent for offshore wind power grouting material and preparation method of C-F-S-H crystal nucleus early strength agent
The invention discloses a C-F-S-H crystal nucleus early strength agent for an offshore wind power grouting material and a preparation method of the C-F-S-H crystal nucleus early strength agent. The C-F-S-H crystal nucleus early strength agent comprises soluble calcium salt, soluble ferric salt, soluble silicate and dispersing agents, and the dispersing agents are sodium polyacrylate and polyethylene glycol; the preparation method comprises the following steps: respectively preparing a soluble calcium salt aqueous solution and a soluble silicate aqueous solution, and adding soluble ferric salt into the soluble calcium salt aqueous solution to prepare a mixed solution; and mixing the mixed solution and a soluble silicate aqueous solution, adding a sodium polyacrylate aqueous solution, then adding polyethylene glycol, adjusting the pH value, and carrying out a stirring reaction to prepare the C-F-S-H crystal nucleus early strength agent. The C-F-S-H crystal nucleus early strength agent has good long-term dispersion stability, can significantly improve the mechanical properties and durability of the offshore wind power grouting material at each age, especially can significantly improve the early strength of the offshore wind power grouting material, and has no adverse effect on the durability of the offshore wind power grouting material.
本发明公开了一种用于海上风电灌浆料的C‑F‑S‑H晶核早强剂及其制备方法，该C‑F‑S‑H晶核早强剂包括可溶性钙盐，可溶性铁盐，可溶性硅酸盐及分散剂，分散剂为聚丙烯酸钠和聚乙二醇；制备时分别配制可溶性钙盐水溶液和可溶性硅酸盐水溶液，并将可溶性铁盐加至可溶性钙盐水溶液中配制成混合溶液；将混合溶液、可溶性硅酸盐水溶液混合后，加入聚丙烯酸钠水溶液，随后加入聚乙二醇，调节pH并搅拌反应，制得该C‑F‑S‑H晶核早强剂。本发明的C‑F‑S‑H晶核早强剂长期分散稳定性好，能显著提高海上风电灌浆材料的各龄期力学性能和耐久性，尤其是能显著提升海上风电灌浆材料的早期强度，且对其耐久性没有产生不利影响。
