Ultrahigh-strength offshore wind power grouting material containing solid waste-based cementing material and preparation method thereof
The invention relates to an ultrahigh-strength offshore wind power grouting material containing a solid waste-based cementing material and a preparation method of the grouting material. The grouting material comprises a solid raw material and a liquid raw material, the solid raw materials comprise Portland cement, a solid waste-based cementing material reinforcing agent, ultrahigh-activity silicon powder, fly ash microspheres, designed graded fine sand, a high-performance composite water reducing agent, a composite expanding agent and a defoaming agent; the mass ratio of the liquid raw material to the solid raw material is (0.08-0.085): 1. During preparation, 90% of the measured liquid raw materials are poured into a stirring pot, then the mixed solid raw materials are poured into the stirring pot and stirred until slurry is uniform, then the rest 10% of the liquid raw materials are added, and stirring continues to obtain the grouting material. The offshore wind power grouting material disclosed by the invention has the characteristics of large flow regime, adjustable slump retaining time, slight expansion, ultrahigh early and later strength, high elastic modulus and excellent durability, and is a grouting material product which is good in comprehensive performance and more suitable for offshore wind power compared with a common grouting material.
本发明涉及一种含固废基胶凝材料的超高强度海上风电灌浆料及其制备方法，灌浆料包括固态原料和液态原料，固态原料包括硅酸盐水泥、固废基胶凝材料增强剂、超高活性硅粉、粉煤灰微珠、设计级配细砂、高性能复合减水剂、复合膨胀剂和消泡剂；液态原料和固态原料的质量比为(0.08‑0.085):1。制备时，将量取的90％的液态原料倒入搅拌锅，然后倒入混合好的固态原料搅拌至浆体均匀，之后加入剩余的10％的液态原料，继续搅拌得到所述灌浆料。本发明所述海上风电灌浆料，具有大流态、保坍时间可调节、微膨胀、超高早期后期强度、高弹性模量、耐久性优异的特点，相比于普通灌浆料，是一种综合性能好、更适用于海上风电的灌浆料产品。
