Air Entrainment Meter Pressure Gauge The air entrainment process is crucial for creating strong concrete that can weather the elements. As such, the concrete air test is just as necessary as other common strength and slump tests

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.


Air Entrainment Meter Product Overview

  • locking bolts with palm grip give the test pot and upper section an airtight seal.
  • Two ball cocks are provided to fill the required water and to vent the air.
  • The air is compressed by means of a built-in hand pump.
  • Capacity: 5 litres, 10 litres, 100 litres
  • Air content range: 0 – 100%
  • Gauge graduations: 0.1% up to 6% of the scale; 0.2% from 6%
    to 10% of the scale
  • Gauge graduations: 0.1% up to 6% of the scale; 0.2% from 6%
    to 10% of the scale.
  • Lightweight, compact and durable, this meter
    allows quick clamping system and testing with few pump strokes.
  • It is not affected by a change in atmospheric pressures.
  • The container can be used also for unit weight measures of fresh concrete and aggregates.
  • Supplied complete with NABL Calibration

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.
