Tortuous pore structure of GGBFS and limestone powder blended concrete described by multi-cycle mercury intrusion porosimetry

Author

Abstract
The tortuosity of the pore structure is an important factor affecting transport of species in cement-based materials; hence it constitutes a valuable tool for predicting their durability performance. A textural analysis of the pore structure of GGBFS and limestone powder blended concrete is assessed by multi-cycle mercury intrusion porosimetry (MIP). The synergy between the mineral admixtures is inferred from the comparison of results to those of equivalent Portland cement concrete, and binary blended concretes containing only GGBFS or limestone powder. Water-to-binder ratio was 0.4 in all cases. Three intrusion-extrusion cycles were applied to each sample. Upon consideration of the possible causes of the hysteresis during the experiments, the evaluations include quantifications of the total porosity, pore-neck size distribution, threshold pore sizes, and pore entrapment. The results depict the advantages of using multiple intrusion-extrusion cycles during MIP experiments, with an evaluation of the relative tortuosity of the blended mixes as a significant outcome.
