CRMCA Program Manager, JT Mesite, continues the Online Concrete Procedures series by CRMCA with ASTM C231 Air Content of Freshly Mixed Concrete by the Pressure Method. This Standard is the procedure for determining air content using pressure. This procedure discussed the full procedure including differences when testing allows for only the Air by Pressure method to be performed versus performing Unit Weight before. We will continue to share videos through our CRMCA YouTube channel that outline the procedures, trick, and tips on concrete testing in both the field and laboratory.
