When water transforms from liquid to solid during the process of freezing, it increases in volume by 9 percent. Therefore, when water moisture in concrete freezes, it creates pressure that, if exceeding the tensile strength of the concrete, will result in ruptures within the concrete. Continuous exposure to freeze-thaw cycles increases the likelhood of damage to the concrete. Resistance to this freeze-thaw effect is achieved by air entrainment due to the stress-relieving properties of the air inside the concrete during below-zero temperatures.\u003c\/p\u003e\n\u003cp\u003eA secondary advantage of air-entrained concrete is the increased ease with regard to the workability of the concrete during its plastic state.\u003c\/p\u003e\n\u003cp\u003eIt is important that neither too much nor too little air is situated within the concrete.
