Internal Curing
Internal curing is the process of “curing concrete from the inside out” by using prewetted lightweight aggregates that gradually release water throughout the concrete mix.
This technique, defined by the American Concrete Institute (ACI) as “a process by which the hydration of cement continues because of the availability of internal water that is not part of the mixing water,” helps reduce shrinkage, cracking, and permeability in concrete.
Arcosa Lightweight’s expanded shale and clay aggregates provide an efficient solution for internal curing, resulting in more robust, durable concrete with extended service life.
