Underwater Non-Dispersible Grouting Material

Product Overview

Underwater Non-Dispersible Grouting Material is a specially formulated cement-based material developed for underwater repair and reinforcement. It features excellent anti-dispersal performance, high fluidity, self-compacting ability and rapid strength development, ensuring stable construction quality in underwater environments.

Product Features

Excellent Anti-Dispersal Performance
Does not easily disperse or wash out during underwater construction, maintaining material stability and ensuring underwater grouting quality.
Fast Strength Development
1d compressive strength 15-40MPa, 28d 50-90MPa, quickly meeting underwater structural load-bearing requirements.
Excellent Flowability
Initial flowability β‰₯342mm, 30min β‰₯338mm, suitable for pouring into complex underwater spaces.
Micro-Expansion Performance
3h vertical expansion rate 0.1%-3.5%, compensating for shrinkage and ensuring dense filling.
Self-Compacting Performance
Self-leveling without vibration, autonomously filling complex underwater gaps and voids.
Low Chloride Ion Content
Chloride ion content <0.1%, no corrosion risk to rebar, ensuring long-term durability of underwater structures.
