New Approved ASTM Standards

There have been several approvals to updates of important ASTM standards affecting concrete producers in the last few months.

C1227 - Standard Specification for Precast Concrete Septic Tanks has been revised to C1227-08. This specification covers design requirements, manufacturing practices, and performance requirements for monolithic or sectional precast concrete septic tanks.

C231 - Standard Test Method for Air Content of Freshly Mixed Concrete by the Pressure Method has been revised to C231-08. The test determines the air content of freshly mixed concrete, exclusive of any air that may exist inside voids within aggregate particles.
