The incorporation of air in the form of bubbles as a dispersed phase in the bulk liquid Air may be entrained in a liquid through mechanical means and/or by release of dissolved air due to a sudden change in environment The presence of entrained air is usually readily apparent from the appearance of the liquid (i e , bubbly, opaque, etc ) while dissolved air can only be determined by analysts
The incorporation of air in the form of bubbles dispersed in a fluid Common when an improper amount of antifoam agent is added to reduce foaming
microscopic air bubbles in the cement paste that allows space for expanding moisture during freeze cycles
The incorporation of air (bubbles) as a dispersed phase in a liquid Air entrainment may result from mechanical means or by sudden environmental changes The presence of entrained air is usually obvious from the hazy, opaque, or bubbly physical appearance of the liquid while dissolved air can only be determined by specific testing
