Full Name

ICC-ES AC493 – Acceptance Criteria for Composite, Ultra-high Performance Concrete (UHPC) Panel Systems

Scope

ICC-ES AC493 establishes the acceptance criteria for evaluating composite, ultra-high-performance concrete (UHPC) panel systems used in building construction. These panels are made of a combination of UHPC and other materials, such as steel reinforcement or fiber-reinforced polymers, and offer high strength, durability, and aesthetic appeal. The scope of AC493 includes:
  • Material properties: it specifies the requirements for the materials used in UHPC panel systems, including the UHPC mix design, reinforcement materials, and connection details between panels and supporting structures.
  • Design and manufacturing: it outlines the design criteria for UHPC panels, considering factors such as structural performance, fire resistance, and durability. It also addresses the manufacturing process and quality control measures to ensure consistent product quality.
  • Testing: it details the specific tests required to evaluate the performance of UHPC panel systems under various conditions, including structural load tests, fire resistance tests, and durability tests.
  • Evaluation and certification: it outlines the process for evaluating and certifying UHPC panel systems to ensure they comply with the acceptance criteria and can be safely used in construction.
By adhering to ICC-ES AC493, manufacturers can demonstrate that their UHPC panel systems meet the necessary performance and safety standards. It also provides valuable information to architects, engineers, and builders for selecting and incorporating suitable UHPC panels in their projects.
