C457 Parameters of the Air-Void System
Point count analysis to determine air content and parameters of the air-void system in hardened concrete is done according to ASTM C457. This service includes sample preparation and the report gives the detailed parameters determined in the counting of at least 2000 points. If required, an estimate of entrapped air is provided as the volume percent of voids with chord lengths of 1mm and larger.
