Freeze-Thaw Durability of Concretes with and without Class ...

The freeze-thaw resistance of concretes was studied. Nine concrete mixes, made with five cements and cement-Class C fly ash combinations, were exposed to freeze-thaw cycling following 110 to 222 days of moist curing. Prior to the freeze-thaw cycling, the specimens were examined by a low-vacuum scanning electron microscope (SEM) for their microstructure.

Freeze-Thaw Resistance - Portland Cement Association

Freeze-Thaw Resistance. When water freezes, it expands about 9 percent. As the water in moist concrete freezes it produces pressure in the pores of the concrete. If the pressure developed exceeds the tensile strength of the concrete, the cavity will dilate and rupture. The accumulative effect of successive freeze-thaw cycles and disruption of ...

Freeze-Thaw Durability of Low-Permeability Concrete

good concrete F-T durability was associated with a proper air system, especially the proper amount of small air voids and spacing factor. Without air entrain-ment, the combination of low permeability and high strength makes concrete F-T durable. Though it is difficult to achieve in the field, such low-permeability,
