Calcium aluminate cement gives concrete high strength at its early age, this type of concrete can be used for bridges, viaducts, concrete and asphalt roads to be repaired and to ensure that they are re-opened for usage as soon as possible. The concrete is exposed to outside influences such as places exposed to water, especially in cold climate regions the concrete will have a significant freeze-thaw problem. To improve the freeze-thaw resistance of hardened concrete, air-entraining additives are used. In this paper, many concrete samples were obtained by using different amounts of calcium aluminate cement with air-entrainig additives. The concrete samples' vacuum structure and the degree of vacuum that they are subjected to during the process of tomography, the image processing method and the microscopic examination are compared.
