Air content Controls Group

Air content test is typically required for checking air-entrained concrete in areas where frost-related damage can occur. Air-entraining admixtures added to the concrete mixture create uniform and stable air bubbles in the fresh concrete. These voids will allow water to expand during freezing phase without damaging the hardened concrete. The ...

Aug 30, 2016  Air entraining agent (AEA) can bring a lot of microbubbles into fresh concrete for improving its fluidity; however, high fluidity has adverse effect on the shootability of wet-mix shotcrete. In order to solve the contradictory issue, the paper developed a new type of green switch air entraining agent (GSAE) that can improve both the pumpability and shootability.

Effect of Air Entrained Concrete on Strength of Concrete

Normal reduction in strength of concrete by use of air-entrained admixtures varies from 3 to 7%. This variation of strength shall be considered in the mix design of concrete so that a desired compressive strength is achieved with required amount of admixture and workability. Suitably, trial mix designs should be done to find exact variation of strength with the use of this admixture and ...
