Low-temperature environment cement-based grouting material and preparation method thereof
The invention belongs to the field of building materials, and concretely discloses a low-temperature environment cement-based grouting material and a preparation method thereof. The cement-based grouting material is prepared from, by weight, 40-55% of cement, 35-60% of aggregate, 6-16% of a mineral admixture, 0-6% of fibers and 2-4% of an additive; and the sum of the weight percentages of the components is 100%, and the cement-based grouting material further comprises water accounting for 10.5-14.5% of the sum of the weight percentages of the components. The low-temperature environment cement-based grouting material provided by the invention has the advantages of high strength, self-compaction, micro-expansion, high durability and the like.
本发明属于建筑材料领域，具体公开了一种低温环境水泥基灌浆材料及其制备方法。所述水泥基灌浆材料按重量百分比计，其原料组成如下：水泥40％～55％；骨料35％～60％；矿物掺合料6％～16％；纤维0％～6％；外加剂2％～4％；以上各组分重量百分比之和为100％，以及水，为以上各组分重量之和的10.5％～14.5％；本发明提供的低温环境水泥基灌浆材料具有高强、自密实、微膨胀、高耐久性等优点。
