Expected Benefits:	An expedited method of assuring the correct air-void spacing in concrete.
Deliverables:	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 rapidly cure new concrete 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.
