MAP Brief: Internal Curing

A recent MAP (Moving Advancements into Practice) Brief written by Jason Weiss of Oregon State University outlines how internally cured concrete mixtures can be designed using the mixture proportions of conventional concrete with properties of fine lightweight aggregate.

The article discusses the primary concepts behind internal curing, describes tools for use in mixture proportioning and quality control, and discusses potential concrete pavement applications.

About Internal Curing

For the last two decades, the concept of internal curing has been a subject of laboratory research. Recently, however, internal curing has made the transition from the laboratory to field trials and finally to field implementation. Field experience has shown that, in general, internally cured concrete has similar workability, similar strength and mechanical property development, reduced stress development and cracking, and improved durability when compared with conventional concrete.

About MAP

The Long-Term Plan for Concrete Pavement Research and Technology (CP Road Map) is a national research plan developed and jointly implemented by the concrete pavement stakeholder community. Publications and other support services are provided by the Operations Support Group and funded by TPF-5(286). Moving Advancements into Practice (MAP) Briefs describe innovative research and promising technologies that can be used now to enhance concrete paving practices.
