Early Age Stresses and Creep-Shrinkage Interaction of Restrained Concrete

The analysis revealed stress-induced shrinkage as a major mechanism of drying creep for plain and fiber reinforced concrete (FRC). Microcracking forms a significant portion of drying creep of plain concrete, but it is less significant in FRC. Therefore, creep of FRC is dominated by real mechanisms, whereas apparent mechanisms induced by microcracking is significant in plain concrete. The real creep mechanisms are beneficial because they provide tensile stress relaxation, but the apparent mechanisms are associated with microstructural damage and are detrimental. Therefore, FRC enhances stress relaxation and delays the time of shrinkage cracking.
