Freezing resistance
WebFreezing stress resistance is generally regarded as a complex trait with multigenic inheritance (Marshall, 1982; Stushnoff et al., 1984; Blum, 1988). However, there is no consensus on the mode of gene action. For example the … WebPolar fishes are known to have serum proteins and glycoproteins that protect them from freezing, by a noncolligative process. Measurements of antifreeze concentrations in ice and scanning electron micrographs of freeze-dried antifreeze solutions indicate that the antifreezes are incorporated in ice during freezing.

Concrete gains very little strength at low temperatures. Accordingly, freshly placed concrete must be protected against freezing until the degree of saturation of the concrete has been sufficiently reduced by cement hydration.
