Development of a shrinkage performance specifications and prediction model analysis for supplemental cementitious material concrete mixtures

Based on a comparison of the unrestrained drying shrinkage and restrained cracking tendency, it was determined that the potential for cracking could be minimized by limiting the unrestrained shrinkage of the concrete mixtures. The recommended percentage length change specification limits for the supplemental cementitious material mixtures are 0.0400 at 28 days and 0.0500 at 90 days.
