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.

Example Embodiment

[0039] Preparation Example corrosion waterproof cement-based grout having 1 to 5 comprising the following steps:
[0040]. S1 was added sand, cement, viscosity reducer, metakaolin, superfine quartz powder, preservative curing agent, synthetic fibers, stirred for 1 ~ 2min;
[0041]S2. The resulting product was then added to the step S1 antifoaming agent and water-soluble reducing agent, stirred for 3 ~ 5min, was thoroughly mixed to form the cement-based grout mix was controlled by water-reducing agent and water, of the flow is maintained within the range of 320 ± 30mm;
[0042]. S3 to cement-based grouting material obtained in step S2 mix was then added modified nano-silica dispersion and a shrinkage-reducing agent, 2 ~ 3min stirred mix was obtained;
[0043]. S4 step S3 the resulting mix was charged molding, ≥95% relative humidity environment of room temperature curing 1 ~ 7d;
[0044] S5. Finished form removal after curing, room temperature curing for 7 ~ 14d at a humidity of ≥95%, a temperature of 10 ~ 40 ℃ of.
