"The main objective of this study was to determine the effect on bond performance of high-volume fly ash (HVFA) concrete and self-consolidating concrete (SCC). The HVFA concrete test program consisted of comparing the bond performance of two concrete mix designs with 70% cement replacement with Class C fly ash relative to a Missouri Department of Transportation (MoDOT) standard mix design. The SCC test program consisted of comparing the bond performance of normal and high strength SCC with their respective MoDOT standard mix designs.

Two test methods were used for bond strength comparisons. The first was a direct pull-out test based on the RILEM 7-II-128 "RC6: Bond test for reinforcing steel. 1. Pullout test" (RILEM, 1994). The direct pull-out tests were performed on specimens with #4 (#13) and #6 (#19) deformed reinforcing bars.

The second test method consisted of a full-scale beam splice test specimen subjected to a four-point loading until failure of the splice. This test method is a non-ASTM test procedure that is generally accepted as the most realistic test method for both development and splice length. The beam splice tests were performed on beams with #6 (#19) reinforcing bars spliced at midspan at a specific length to ensure bond failure occurs prior to shear or flexural failure.

Analysis of the HVFA concrete data indicates that using greater than 50% replacement of cement with fly ash in concrete does not result in any increase in the required development length of mild reinforcing. Analysis of the SCC data indicates that using SCC does not result in any increase in the required development length of mild reinforcing"--Abstract, page iii.
