ASTM C173/C173M is the standard test method for measuring the air content of freshly mixed concrete by the volumetric method. It provides a practical way to evaluate how much air is present in fresh concrete, which can be important for mix verification, quality control, and performance consistency. For producers, contractors, and testing labs, this ASTM standard helps support reliable field and laboratory testing when fresh concrete air content needs to be checked.

Overview of ASTM C173/C173M

The official title, Standard Test Method for Air Content of Freshly Mixed Concrete by the Volumetric Method, shows that this document focuses on a specific procedure for determining air content in fresh concrete. ASTM C173/C173M is used as a technical reference for the volumetric approach, helping users apply a recognized method during testing and inspection. As an ASTM standard, it supports more consistent evaluation of concrete mixtures where air content is an important quality characteristic.

Common use cases of ASTM C173/C173M

This standard is commonly used when freshly mixed concrete must be checked for air content during production, delivery, or jobsite verification. It is relevant for routine testing workflows in concrete quality control and acceptance-related activities, especially where a volumetric method is preferred or specified. ASTM C173/C173M is also useful for laboratories and field personnel who need a recognized test method to compare mix results and confirm that concrete meets project requirements.

Benefits of using ASTM C173/C173M

Using ASTM C173/C173M can help improve consistency in concrete testing and support more dependable quality decisions. A recognized ASTM method reduces uncertainty in procurement and compliance workflows by giving buyers, suppliers, and testers a common reference point. It can also help reduce risk during product evaluation by providing a standardized way to assess fresh concrete air content, which supports clearer communication and more reliable test records.
