Featuring on low adding amount, high strength, high expansion rate and short time to reach steady expansion. It is applicable to resist permeation and leaking under ground, corrosion resistance construction, compensate dry shrinkage with self-stressing and develop new special engineering materials. Now it has been exported in batch. The main physical properties are as follows. |
