This work aimed to verify the feasibility of reducing the drying shrinkage of concrete made with portland pozzolan cement. Major variables included slump, shrinkage-reducing admixture (SRA) brand and dosages, and specimen dimensions. Tests were conducted on 132 prism specimens and shrinkage strains were measured up to 360 days of drying. Compressive and splitting strength and static modulus of elasticity were also determined. Based on the obtained results, it was concluded that all 5 of the brand admixtures evaluated reduce drying shrinkage. One experimental admixture exhibited the best behavior and reduced up to 45% of the average free shrinkages of concrete at 360 days of drying. Results were compared with drying strain predictions of ACI, CEB, B3, GL, Sakata, and Sakata 2001 models. It was concluded that, in general, all the analyzed shrinkage models do not adequately represent the observed shrinkage behavior of concretes made with portland pozzolan cement and SRAs. Therefore, 2 prediction models to estimate drying shrinkage strains were developed based on ACI drying-time function and Sakata's ultimate shrinkage strain. One of the models is for use at a design level when no information about a particular SRA is known, and the other is applicable to concrete made with a particular admixture brand.
