Anti-corrosion waterproof cement-based grouting material and preparation method thereof

The invention belongs to the technical field of building materials, and particularly relates to an anti-corrosion waterproof cement-based grouting material and a preparation method thereof. The technical key points are as follows: the anti-corrosion waterproof cement-based grouting material comprises the following components in parts by weight: 750-1000 parts of cement, 80-200 parts of a viscosity reducer, 5-30 parts of a modified nano silicon oxide dispersion liquid, 50-150 parts of metakaolin, 50-100 parts of superfine quartz powder, 20-100 parts of an anti-corrosion curing agent, 20-50 parts of a water reducing agent, 1-3 parts of a defoaming agent, 10-30 parts of a shrinkage reducing agent, 900-1100 parts of sand, 160-240 parts of water and 2-4 parts of synthetic fibers. By adopting the nano silicon oxide dispersion liquid, the metakaolin, the shrinkage reducing agent and the anti-corrosion curing agent, the cement-based grouting material with excellent anti-corrosion performance and good waterproof effect can be obtained under conventional curing conditions, and the cement-based grouting material has good economic benefits and practical values.
