Internal curing is a method of curing the concrete from the inside by “hiding” water in the lightweight aggregates. The benefits of internal curing include a well distributed network of water to cure as needed throughout the mixture. A long term benefit is the potential extension of the concrete’s service life. Mixture proportioning for concrete designed with internal curing is as simple as replacing a portion of the sand with prewetted, fine lightweight aggregate.

Part 2 includes the presentation covering “Shrinkage and Shrinkage Cracking.”
