Test Methodology:   Compare scanning and image analysis techniques with traditional C457 point count and linear traverse methods.
Partners:   Federal Highway Administration: Office of Research, Development, and Technology - Office of Infrastructure Research and Development; Role(s): Technical
Expected Benefits:   An expedited method of assuring the correct air-void spacing in concrete.
Deliverables: 1. Name: A rapid image analysis method for evaluating the air-void distribution in hardened concrete.
Product Type(s): Research report, Data, Draft standard, specifications, or guidelines, Techbrief
Description: The concept is to cure new concrete rapidly and then prepare a polished section to evaluate using automated image analysis to give an indication of the air content and dispersion of the air bubbles exposed at the surface of the polished section.
