ICC-ES AC562
Full Name
ICC-ES AC562 – Acceptance Criteria for Textured Epoxy-coated Steel Reinforcing Bars
Scope
ICC-ES AC562 outlines the acceptance criteria for evaluating textured epoxy-coated steel reinforcing bars used in concrete construction. These bars are designed to improve bond strength and corrosion resistance compared to uncoated or conventionally coated bars.
The scope of AC562 includes the following aspects:
- Material properties: evaluating the mechanical properties of the steel reinforcing bars, including tensile strength, yield strength, elongation, and bendability.
- Coating properties: assessing the properties of the textured epoxy coating, such as thickness, adhesion, abrasion resistance, and chemical resistance.
- Bond performance: evaluating the bond strength between the coated bars and concrete under various loading conditions.
- Corrosion resistance: assessing the corrosion resistance of the coated bars in different environments, including chloride-laden and carbonated concrete.
- Manufacturing process: evaluating the manufacturing process and quality control measures to ensure consistent production of high-quality textured epoxy-coated bars.
The evaluation process typically involves a combination of laboratory testing, field testing, and review of manufacturer’s documentation to verify compliance with the acceptance criteria.
