Abstract

Early-age cracking can be a significant problem in concrete pavements, floors, and bridge decks. This paper describes restrained ring (i.e., restrained shrinkage) tests to assess how fiber reinforcement and a shrinkage reducing admixture (SRA) influence the residual stress development and potential for early-age cracking in a mixture. An analytical solution is provided to relate the strains that are measured in the steel ring to the residual stresses and crack widths that develop in the concrete ring. Results from passive acoustic emission are presented to illustrate how damage (i.e., microcracking) develops in these systems.
