Visible frost damage develops after an accumulation of micro-cracks as a result of several freeze-thaw cycles. [ 1 ] [ 2 ] Frost damage can be prevented by the use of frost-proof materials, i.e. , a material which has sufficient closed pores, by which the volume increase caused by the freezing of water in capillary pores can be absorbed by the ...
Photograph taken 21 March 2010 in Norwich, Vermont. Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface, upwards from the depth in the soil where freezing temperatures have penetrated into the soil (the freezing front or freezing boundary).

These are created during concrete mixing (while the slurry is in its liquid state), with most surviving to remain part of it when hardened. Air entrainment makes concrete more workable [1] during placement, and increases its durability when hardened, particularly in climates subject to freeze-thaw cycles. [2] It also improves the workability of ...

Central Florida — and Orlando, where it dropped to 30 — was in the low- to mid-30s, Redman said. North of Orlando, in North Central Florida and Ocala, it dipped to the upper-20s.
Research from major concrete authorities, including the American Concrete Institute, Portland Cement Association, and the National Ready Mixed Concrete Association confirm that most concrete damage is attributable to surface moisture intrusion. [citation needed] The most pervasive form of concrete damage is surface scaling from freeze/thaw.
