00:04 Controlling air content in concrete mixtures is a necessary component in their mix design. Small air bubbles create voids to relieve the pressure of water as it expands when freezing, thus preventing damage and relieving pressure during freeze thaw cycles.

And Gilson offers a complete selection of air meters for testing fresh concrete specimens in accordance with ASTM and AASHTO standards test methods.

00:27 Gilson offers two high-quality Type B Concrete Air Meters which measure total air content from the fresh concrete sample. The HM-30 model features the exclusive rugged and waterproof Gorilla Gauge, while the economical HM-30S offers an American-made stainless-steel gauge. Both feature rugged construction, portability, and ease of operation for fast and accurate air content determinations in field in accordance with ASTM and AASHTO test specifications.

01:06 The HM-345 Super Air Meter (SAM) is a modified version of a conventional Type B Concrete Air Meter that determines both total air content and the air void spacing factor of fresh concrete specimens. And provides a good indication of freeze-thaw durability. This rugged unit is equipped with a programmed digital gauge that easily guides the user through the ASTM and AASHTO test procedures.

01:35 Gilson also offer two volumetric air meters for testing lightweight aggregate concrete mixes, but either unit can reliably be used with any concrete mix. The HM-32L Gilson Lightweight Concrete Roll-A-Meter is a lightweight version of the popular roller meter and is constructed of durable aluminum. And the HM-33 Volumetair™ is constructed of PVC and fiberglass-reinforced plastic. Readings of percent of air are easily obtained on the sight tube scale in accordance with ASTM and AASHTO test specifications.

And finally, the 02:14 Gilson HM-34 Chase Air Indicator Kit is an easy-to-use tool for quick estimates of the air content in fresh concrete in the field as a supplement to other standard air meter tests.
