    What is Air-Entraining Admixture and Its Effect on Concrete

    Factors Affecting the Amount of Air-Entraining Admixture: The making of air-entraining concrete is somehow little complicated considering that the amount of air-entraining admixtures in a mix is affected by many factors; the important ones are: 1) The types and quantity of air entraining agent used. 2) Water/cement …

    Air Entraining Admixtures for Concrete

    Entrained vs. Entrapped Air: The air content of concrete is made up of entrained and entrapped air voids. Entrained air refers to microscopic air bubbles intentionally incorporated into concrete during mixing, usually by use of a surfaceactive agent. These - bubbles are spherical with diameters between 0.0004 and 0.04 in. (0.01 and 1 mm).
