Quick Details
Specifications
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 admixture.
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.
