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 3 includes the presentations covering “Mechanical and Transport Properties,” and “Improving Sustainability with Internal Curing.”

1. Understand the changes that occur in concrete due to internal curing.
2. Understand the influence of internal curing on durability of concrete (transport, freeze-thaw, and corrosion).
3. Explain how service life can be improved by using internal curing.
4. Discuss potential ways that internal curing can be used in sustainable design.
