Due to the significant reduction in rebound rate, the alkaline cement dust in the air that pollutes and harms the human body is greatly reduced, protecting the environment and accelerating the construction progress. It has the effects of micro-expansion, shrinkage reduction and crack resistance, greatly improving the anti-seepage and waterproof performance, and at the same time has corrosion resistance and anti-corrosion function, and the corrosion resistance coefficient is increased by more than 50% compared with ordinary quick-setting agents. High-performance quick-setting agent is the preferred material for shotcrete, alkali aggregate active concrete, durable concrete and environmental protection projects.

[0004] There are two forms of alkali-free quick-setting agents, one solid and one liquid. From the user's perspective, the liquid is easy to use and does not need to be mixed at the construction site. It is very convenient to use right away. Utility Model Content
