A new process by which cyclic freezing can damage concrete-the Erlin/Mather effect a concept
The damaging effects of freezing and thawing in concrete are discussed. The ice formed in the cavity contracts and the peripheral space created by the contraction fills with unfrozen pore fluid that has migrated to the freezing front. When the increment of pore fluid freezes, there is a volume increase of thermal increment of such fluid. Subsequent exposure to cyclic subfreezing temperatures causes ice in the capillary cavity to expand and contract attended by a small incremental volume.
