    Abstract

    A method is derived that makes possible the determination of the fraction of hardened cement paste within any stipulated distance of the nearest air void as a means of determining the extent to which the paste is protected from the damaging effects of freezing. The required input consists of the total air content and the number of air voids per unit volume. Both can be determined from a Rosiwal linear traverse performed by microscope on a polished section of concrete. Determining the void density requires a count of chord intercepts in two or three small size groups.
