This type of concrete is used where the concrete is vulnerable to freezing and thawing action. It is prepared by adding the air entraining admixture. The air entrainment in concrete does the following functions: It lowers the surface tension of water and thus bubbles are created. Secondly the air entraining agents prevents coalescing i.e. the combining of bubbles. The diameter of these bubbles
