Abstract
Long-term drying and autogenous shrinkage were measured on 66 HPC mixtures produced during the CONLIFE project. The results were evaluated and compared to existing shrinkage prediction models. The analysis found that drying shrinkage was more of a concern in mixtures with a high w/b ratio, while autogenous shrinkage was dominant for low w/b ratio mixtures. The mineral admixtures played a role in altering the shrinkage due to the water demand and refinement of the pore structure. The existing models typically over-predicted the drying shrinkage. More extensive testing of HPC should be done in order to modify the shrinkage prediction tools to account for low w/b ratios and the use of mineral admixtures.
