Calibration of Shrinkage Behavior of High-Strength Concrete (HSC) Subjected to Accelerated Curing at Early-Age

A research study was undertaken to determine the effect of early-age accelerated steam curing on the shrinkage behavior of High–Strength Concrete (HSC). Typically, accelerated steam cured specimens will exhibit less shrinkage than conventionally cured specimens due to reduced drying shrinkage. In this study, specimens were subjected to various accelerated curing temperatures, including laboratory and moist curing conditions. The variables included were: two water–cementitious materials (w/cm) ratios typically utilized for HSC, fly ash replacement of cement, and partial application of a surface sealant to retain moisture. Results from this study were compared to the current NCHRP 496 shrinkage prediction model for HSC used in the determination of prestress losses. Correction factors are presented to account for reduced shrinkage in accelerated steam cured specimens.
