Internal Curing – Supplying water throughout a freshly placed cementitous mixture using reservoirs, via pre-wetted lightweight aggregates, that readily release water as needed for hydration or to replace moisture lost through evaporation or self-desiccation. – American Concrete Institute (ACI)

Benefits of Internally Cured Concrete Include:

• Reduce the potential for cracking
• Reduce chloride ingress and delay corrosion
• Improve construction robustness (plastic cracking, thermal cracking, etc.)

There are 120 citations regarding Internal Curing on the National Institute of Standards and Technology (NIST) website.
