CRITICAL MOISTURE CONTENTS AT FREEZING OF POROUS MATERIALS
The frost resistance of a material in a function of the materials and the environmental properties. The materials properties are expressed on a critical degree of saturation SCR. SCR cannot be exceeded at one single freezing without risk of substantial damage. The environmental properties are expressed in an actual degree of saturation, SACT. Its value depends on the way of using the material. The frost resistance is then defined as the difference between SCR and SACT. This approach has many advantages such as: -It makes a rapid and general freeze- test method possible; -Consideration can be taken to different ways of using the material; - The frost resistance gets quantified which facilitates rational materials choice; - Relations between materials properties and frost resistance are better understood; - It clarifies many obscurities connected to the problem of frost resistance.
