About the Research

Internal curing (IC) is a practical way of supplying additional curing water throughout the concrete mixture. This water can improve the hydration of cement, reduce autogenous shrinkage, and improve durability. The purpose of this document is to provide guidance for the development of project specifications for internally cured concrete projects. The guidance in this document is designed to supplement the agency’s standard specifications for concrete pavement. If the standard specifications are outdated, modifications other than those provided in this document may be necessary to produce a high-quality, long-lasting concrete. This document contains IC specification language, references to IC resources, references to IC instructional videos, and references to tools that can be used for IC of concrete or providing quality control.
