Standard Method of Test for Characterization of the Air-Void System of Freshly Mixed Concrete by the Sequential Pressure Method
Also Known As:
AASHTO TP 118-17 (2018) is a standard method of testing that is used to characterize the air-void system of freshly mixed concrete. The method involves determining the air content and system air metric (SAM) number of the concrete by observing the change in volume of the concrete with a sequential change in test pressure.
The purpose of this standard is to provide a consistent and reliable method for evaluating the air-void system of freshly mixed concrete. The air content and SAM number are important parameters in determining the durability and freeze-thaw resistance of concrete.
By measuring the change in volume of the concrete at different test pressures, this method allows for a quantitative assessment of the air-void system. The results can be used to determine if the concrete meets the specified requirements for air content and SAM number, and to make adjustments to the mix design if necessary.
