Effect of CCWC on the Self-Healing Action and the Microstructure of Cement-Based Materials
The performance of Capillary Crystalline Waterproofing Coatings(CCWC) was measured by its impermeability and self-healing ability. At the meantime, the microstructure of mortar treated by CCWC was researched with SEM and XRD. The results showed that Ionic transmission could cause a chemical reaction, generate a great quantity hydrate products to block up the pores and cracks in cement-based materials, endow it with self- healing ability, and increase its durability. With increment of the coverage rate, pores and cracks of cement-based materials can be better healed with ionic transmission.
