Abstract:
Basic information is given on the freezing of water in concrete. From this information and other pub- lished material an explanation of the mechanism of the action of frost on concrete is developed. The explanation takes into account such factors as the degree of saturation of the concrete, the permeability and strength of the concrete, hydraulic pressures generated during freezing, and air-filled cavities. It is suggested that the hypothesis be made the basis of further frost in concrete. laboratory studies of the action of
