High-fluidity ultrahigh-strength cement-based grouting material and preparation method thereof
The invention discloses a high-fluidity ultrahigh-strength cement-based grouting material comprising the following ingredients in parts by weight: 10 to 30 parts of water, 50 to 150 parts of cementing materials, 60 to 100 parts of quartz sand, 1 to 5 parts of a water reducing agent, 0.1 to 3 parts of a coagulation accelerator and 0.01 to 0.1 part of an expanding agent. The cement-based grouting material has the characteristics of low viscosity, high fluidity, early strength, ultrahigh strength, high toughness, ultrahigh durability, micro-expansion, high compactness, shrinkage resistance and the like, is low in cost, and can meet the requirement of environmental protection. The chloride ion migration and diffusion coefficient of the high-flowability ultrahigh-strength cement-based grouting material is less than 10<-13>, and the high-flowability ultrahigh-strength cement-based grouting material has few pores and can well resist permeation of water and various zwitterions, so that the high-flowability ultrahigh-strength cement-based grouting material is suitable for offshore structure grouting construction. The invention also discloses a preparation method of the high-fluidity ultrahigh-strength cement-based grouting material, wherein the preparation method is simple, simple and convenient to operate, easy in control of preparation conditions and low in requirements on production equipment, and is a method for easily realizing industrial production.
本发明公开了一种高流动性的超高强度水泥基灌浆材料，包括以下重量份的各组分：水10‑30份、胶凝材料50‑150份、石英砂60‑100份、减水剂1‑5份、促凝剂0.1‑3份和膨胀剂0.01‑0.1份。本发明的水泥基灌浆材料兼具有低粘度、高流动性、早强、超高强、高韧性、超高耐久性、微膨胀、高致密性、抵御收缩等多种特性，而且成本低廉、能够满足环保要求。本发明一种高流动性的超高强度水泥基灌浆材料的氯离子迁移扩散系数<10‑13,其孔隙很少，能够很好地抵御水及各种阴阳离子渗入，故极适用于海上结构灌浆施工。本发明还公开了上述高流动性的超高强度水泥基灌浆材料的制备方法，该制备方法简易、操作简便、制备条件容易控制，对生产设备要求较低，是一种容易实现工业化生产的方法。
