Permeability is a true indicator of durability for concrete. The following recommended tests will indicate the effectiveness of the application.

ASTM D4263 - Standard Test for Moisture and Vapor Migration - Plastic Sheet Method

ASTM D5084 - Standard Test for Permeability Of Concrete, Method A

AASHTO 227, Chloride-ion Permeability Test, should not exceed 500C.

The above mix design examples are based on the most comprehensive data available at this time. They are for reference purposes only and are not absolute. These mix design have resulted in the ability to duplicate high performance concrete, at a standard mix design cost, with consistent, quality results.
