Abstract
Three cores were taken from KU Memorial Stadium on 08/17/22 by personnel from Wiss, Janney, Elstner Associates and analyzed for water-soluble chloride content and depth of carbonation. Cores A4 and B4 were taken from original construction dating to the 1920s, and Core C4 was taken from construction dating to the 1960s. All three cores exhibited low chloride contents, approximately 0.01% by mass of concrete at the depth of reinforcement. Core A4 exhibited carbonation to the deepest depth, 3.5 in., while Cores B4 and C4 exhibited carbonation to depths of 1.25 in. and less than 0.25 in., respectively.
