Hi, hydrogen is a cross-linked polymer which is water absorbed and holds due to its hydrophilic properties.
Nowadays, the hydrogel is used as a curing method but it is very expensive so not used worldwide. the hydrogen curing method is only used for very small and important works.
The hydrogel of type sodium acrylate co-acrylamide is basically used for curing.
This is a superior curing method gives has following advantages:
- This avoids the bleeding in concrete members.
- Rate of evaporation of water reduced from inside the concrete.
- Avoids shrinkage problems.
- This allows water to retain inside the concrete for a long time.
