• Abstract:
  The main objective of this study was to determine the effect on bond performance ; of mild reinforcing steel in self-consolidating concrete (SCC). 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 SCC data indicates that using SCC does not result in any increase ; in the required development length of mild reinforcing.
