Title: Effect of Frozen Rebar on Surrounding Concrete During Cold Weather Placement
Author(s): Ronald L. Kozikowski
Publication: Web Session
Appears on pages(s):
Keywords: cold weather concreting
Abstract:The current model for cold weather concreting operations is based on the Thermos Concept–make the concrete hot and then keep it hot. The bulk of the technical aspects of the current ACI 306 document are based on work done over 30 years ago. The practice of cold weather concreting has changed significantly since that time. The changes in cement chemistry and fineness, the widespread use of slower-reacting materials in the interest of sustainability, as well as the ubiquity of the Internet and electronic sensors needs to be incorporated into the revisions to the guide to cold weather concreting as well as to the specification currently under development.
