OVERVIEW

Also, understand Air entrainment Meter describes the process of introducing air-entraining agents into a concrete paste or using cement that is already air-entrained. Billions of microscopic air bubbles fill each cubic foot of the concrete to relieve internal pressure during freeze/thaw cycles.

FAQ?

Why Is Air Entrainment Necessary?

Entrained air pockets act as tiny chambers for water within the concrete to expand as it freezes, which helps reduce the risk of scaling and other common issues. New concrete in particular will benefit, as it is the most likely to have high moisture content and has not yet cured completely to reach its full strength.

Air entrainment in concrete is especially important where salt and deicers will be used, even deicers that are not corrosive. These kinds of chemicals can be hard on concrete because they lower the freezing point of water, which thaws existing ice, but they will often refreeze when the temperature drops below that new freezing point. The result is even more freeze/thaw cycles.

Having the proper air entrainment ratio can help contain the damage caused by natural freeze/thaw cycles as well as those caused by people fighting ice in the wintertime.

How to Perform a Concrete Air Entrainment Test

Concrete air entrainment testing is typically performed on plastic, or fresh, concrete. Pressure method ASTM C 231 is the preferred test for determining air void spacing and volume in concrete. In order to perform the pressure test, you will need an air entrainment meter capable of performing Type B or SAM tests. A good air entrainment meter will produce results within ±1% of the target value in about 10 – 15 minutes. If results fall outside of the 4% to 7% range, the volume of air entrainment will either need to be increased or decreased to ensure the final product has good compressive strength and freeze/thaw resistance.
