Abstract: This paper is aimed at investigating permeation-related properties of high performance concrete utilizing fly ash and microsilica as cement replacing materials. Oxygen permeability, porosity, and sorptivity of concrete incorporating fly ash and microsilica prepared with various water-binder ratios were determined. In order to investigate the influence of curing conditions, moist curing, air curing, and curing at 5°C were employed. A mixing procedure of blended systems has been proposed. Based on the experimentally obtained results, prediction models were developed. These enabled the establishment of isoresponse contours showing the interaction between the various parameters investigated. It was found that there is an interaction of fly ash and microsilica with the level of replacement. The incorporation of 8–12% microsilica as cement replacement yielded the optimum permeability, porosity, and sorptivity values.
