Frost resistance and pore structure of concrete -- Relationships and testing methods
Experiments made on artificially frosted laboratory concretes and old road concrete showed that volume of air voids under 0.3 mm in diam (partial air voild content) is determining factor for resistance to freezing and thawing salts; ratio of this partial air void content (PAVC) to water absorption proved to be suitable characteristic value for evaluation of frost resistance; latter can be increased by means of air-entraining admixtures; methods of measuring air voids in concrete are described.
