An attempt to develop a tool based on analysis of the air void system in concrete for an early assessment of salt frost scaling resistance of concrete is presented. Relations between the air void system parameters and scaling are discussed. A new technique based on the accumulated surface area of all air voids is presented. This is a short description of the project. The full report is available from our division and also includes a) a study of the rate of water absorption at above-knick point level in capillary suction tests, b) a technique for improving the image analysis procedure with respect to edge objects and c) a comparison between different ways of analyzing the air void system
