The Significance of Critical Degrees of Saturation at Freezing of Porous and Brittle Materials

På svenska

Author

Summary, in English

"The paper treats the problem of frost resistance as a general problem for all porous materials. The difference between the new way of defining critical degree of saturation (as a materials constant) and the usual way (as functions of a combination of properties of material and environment) is discussed. Possible definitions of moisture conditions are provided. By comparison of the critical degree of saturation and the actual reached in practise the frost resistance can be expressed by a plain figure which makes a rational choice of material possible. The method is exemplified. On basis of the hydraulic pressure theory connections between materials properties and critical degree of saturation are derived. (29 refs.)"
