This video production is brought to you by the members of the Expanded Shale Clay, and Slate Institute (www.ESCSI.org). This video demonstrates ASTM C173, the Standard Test Method for Air Content of Freshly Mixed Concrete by the Volumetric Method; it is commonly referred to as the Roll-a-Meter test. The Volumetric Air Test method covers the determination of the air content of freshly mixed concrete. It measures the air contained in the mortar fraction of the concrete; it is not affected by air that may be present inside the porous lightweight aggregate particles.
