Abstract
A hypothesis on the mechanism of "salt-scaling" of porous building materials
based on theories for frost heaving in soils and observations made by Powers and Helmuth /1953/ is described. Though the text mainly deals with cement based materials, the mechanism described should be valid for any brittle, porous material. A simplified calculation of possible scalings shows that the hypothesis predicts reasonable values. Results from a first qualitative test support the hypothesis.
