Revision of C231/C231M-17a Standard Test Method for Air Content of Freshly Mixed Concrete by the Pressure Method


The use of Self-Consolidating Concrete (SCC) has become widely accepted throughout the industry. ASTM C231 has no current change in procedures mentioned for handling SCC and needs to have this provision added to avoid confusion and improper handling of SCC when using this method. ASTM C1758 Practice for Fabricating Test Specimens with Self-Consolidating Concrete was developed to provide users with these handling changes and should be referenced by C231 to remain consistent with other fresh concrete standards and proper handling of SCC.
