This　paper　studies　the　freezing-and-thawing　durability　of　cement　concrete　on　the　basis　of　experimental　investigation　of　air-void　parameters,　which　has　a　significant　influence　on　the　durability　of　concrete.　More　specifically,　this　research　firstly　discusses　the　effect　of　air-entraining　agent　types　on　the　air-void　parameters　feature,　and　then　a　rapid　freezing-and-thawing　test　is　conducted　to　assess　the　durability　of　the　concrete　specimens,　so　as　to　observe　the　relationship　between　the　frost　resistance　performance　evaluation　index,　which　is　applied　as　durability　factors　in　this　study,　and　the　air-void　parameters　of　concrete,　such　as　the　air　void　spacing　factor　and　the　air　content　of　cement　concrete.
