Concrete Air Meters | Air Testing Equipment - Gilson Co

These Type B pressure meters, also referred to as pressure air meters or air entrainment meters, measure entrained air in freshly mixed concrete in accordance with ASTM C231 and AASHTO T 152. Super Air Meter (SAM) is similar to a Type B meter, but with modifications. This cast aluminum device determines both air content and air void spacing factor in less than 10 minutes.

Air Entrainment Meter | Qualitest

The Qualitest Advanced Air Entrainment Meter is used to measure the air content of freshly mixed mortar in accordance with the air pressure compensation principle. The Air Entrainment Meter has a pressure chamber in which a predefined pressure is generated. When the overflow valve is opened, the pressure is compensated with respect to the test pot, which is filled with the freshly mixed mortar.

Use of Water Reducers, Retarders, and Superplasticizer

Typical dosage of superplasticizers used for increasing the workability of concrete ranges from 1 to 3 liters per cubic meter of concrete where liquid superplasticizers contained about 40 % of active material. In reducing the water cement ratio, higher dosage is used, that is from 5 to 20 liters per cubic meter of concrete.
