Internally Cured Concrete

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.
