Internal Curing

Because hydration occurs for a longer period of time due to an internal moisture source, internally cured concrete bridges continue to get stronger.

This continued hydration also results in a reduction in permeability.

Early shrinkage of concrete can be mitigated due to the presence of additional internal moisture, and by reducing shrinkage, internal curing enables unwanted cracking to be delayed or eliminated.

Internal curing can increase the service life of high performance concrete (HPC) bridge decks by almost ten years, due to the absence of initial cracking.

​The use of HPC with internal curing in bridge decks can bring an additional economical benefit by delaying the times at which repairs and rehabilitation of the reinforced concrete deck are required.
