A test core from two lifts of self-consolidating concrete undergoes a splitting tension test, with the location of the joint indicated by the line across the diameter. The average peak force registered was 40,000 lbs and the joint strength was in the range of 550 to 600 psi. Splitting tension testing and direct shear testing provided the information the Olmsted team needed to adopt the warm joint. (U.S. Army Corps of Engineers photo by Dave Kiefer)
