HCSA concrete expanding agent
Telephone Bargaining
Main Features:
1. High expansive performance: 7d between the water limit expansive ratio can reach 0.15 - 0.2%. It is 4 - 8 times the expansive volume of ordinary expansive agent.
2. Expansive rate is proper: the 3d water limit volume of expansion can be up to 70 - 80%, 7d was above 85%.
3. Under the condition of 100% dry, it can still maintain larger expansive volume.
4. The performance is stable.
