Application/Uses: |
- Uses:
- 1. It offers higher corrosion resistance due to the inhibitors added to it.
- 2. By using this technology, the service life of concrete structures increased by several folds.
- 3. It does not affect the bond strength in RCC structures.
- 4. The chemicals to be used are available indigenously.
