Enhanced Entrained Air Void System Characterization for Durable Highway Concrete

This project will demonstrate an alternative test procedure to characterize the entrained air void system for hardened concrete. The procedure utilizes a microscope with onboard counting and measuring software to make sophisticated measurements of a prepared sawn or drilled core sample. Additional focus will be placed on minimizing the sample preparation required in ASTM C457 Procedure C. The new procedure and hardware will be developed to be robust (long-lasting), and easily implemented across state agencies.
