The invention relates to the technical field of building materials, is used for enhancing the strength and the flowing effect of a grouting material and reducing the expansion rate, and particularly relates to a high-strength tank grouting material and a preparation method thereof, the high-strength tank grouting material comprises the following components in parts by weight: 420-460 parts of cement, 370-390 parts of sand, 25-35 parts of aluminum sulfate, 25-35 parts of anhydrite, 0.5-1.5 parts of a defoamer, 1.5-2.5 parts of a water reducer, 0.1-0.3 part of hydroxypropyl methyl cellulose (HPMC), 40-60 parts of secondary fly ash, and 40-60 parts of a mixture of silica powder and steel slag micro powder; the preparation method comprises the following steps: adding the components into a proportioning tank according to the dosage ratio, and uniformly stirring and mixing to produce the grouting material. According to the grouting material, the problems that an existing grouting material islarge in volume shrinkage and prone to generating microcracks, so that the lower portion of a support plate is not compact after a support is installed, and the strength is low are solved, and the prepared grouting material is better in fluidity, smaller in expansion rate and higher in strength by controlling the dosage ratio of all the components and through synergistic cooperation of all the components.
本发明涉及建筑材料技术领域，用于增强灌浆料的强度和流动效果，降低膨胀率，尤其涉及一种罐体高强灌浆料及其制备方法，按照重量分数计包括以下组分：420‑460份的水泥，370‑390份的砂，25‑35份的硫酸铝，25‑35份的硬石膏，0.5‑1.5份的消泡剂，1.5‑2.5份的减水剂，0.1‑0.3份的羟丙基甲基纤维素(HPMC)，40‑60份的二级粉煤灰，40‑60份的硅微粉和钢渣微粉混合物；制备方法：按照用量比将各组分加入到配料罐内搅拌混匀即可生产出该灌浆料；解决了目前的灌浆料存在体积收缩较大，易产生微裂纹，导致支座安装后支座板下产生不密实，而且强度低的问题，该灌浆料通过控制各组分之间的用量比，以及通过各组分之间的协同配合，使制得的灌浆料流动性更好、膨胀率更小、强度更高。
