Abstract:
This article summarizes the results and outcome of a research project titled “Development of Specifications and Performance Criteria for Surface Preparation Based on Issues Related to Bond Strength.” Factors affecting “short-term” bond strength are discussed, with primary focus on aspects such as concrete surface preparation and conditioning, treatment of exposed reinforcement, and quality control.
