Grouting material resistant to high saline-alkaline environment and preparation method of grouting material
The invention discloses a grouting material resistant to a high saline-alkaline environment and a preparation method thereof. The grouting material comprises the following components in parts by weight: 40-60 parts of modified gypsum slag cement, 30-50 parts of modified aggregate, 1-3 parts of a polycarboxylic acid water reducer, 2-8 parts of a composite expanding agent, 0.2-1 part of a functional additive and 0.4-2 parts of hybrid fibers. The grouting material can effectively solve the problem of poor saline-alkaline tolerance of the existing grouting material.
本发明公开了一种耐高盐碱环境的灌浆料及其制备方法，该灌浆料包括以下重量份的组份：改性石膏矿渣水泥40‑60分、改性骨料30‑50份、聚羧酸减水剂1‑3份、复合膨胀剂2‑8份、功能助剂0.2‑1份和混杂纤维0.4‑2份。该灌浆料可有效解决现有的灌浆料存在的耐盐碱性能差的问题。
