Implementation of the Sequential Air Method in Laboratory and Field Studies
MetadataShow full item record
This work validates the Sequential Air Method (SAM) Number by analyzing data from laboratory, industry fieldwork, and a series of concrete mixtures with different admixture combinations. Comparisons are made to the total air content and hardened air-void analysis (ASTM C457) for the 458 concrete mixtures studied. Comparisons are also made to the freeze thaw durability testing (ASTM C666) for the two individual lab data sets with admixtures. Guidelines are established in this work to help users understand the reliability of the air content and SAM Number relationship within a fresh concrete mixture.
