ICC-ES AC556
Full Name
ICC-ES AC556 – Acceptance Criteria for Construction Joints Using Expanded Metal Mesh System
Scope
ICC-ES AC556 establishes the design and performance requirements for expanded metal mesh systems used in construction joints. These systems are designed to accommodate movement and prevent cracking in various types of structures, such as concrete slabs, walls, and floors.
The scope of AC556 includes:
- Material properties: evaluating the properties of the expanded metal mesh, including its tensile strength, yield strength, and corrosion resistance.
- Joint design: assessing the design of the joint system, including the dimensions and configuration of the expanded metal mesh, as well as the connection details with the surrounding materials.
- Performance testing: conducting tests to evaluate the joint system’s ability to accommodate movement, resist cracking, and maintain its integrity under various loading conditions.
- Installation: providing guidelines for the proper installation of the expanded metal mesh system to ensure its effectiveness in controlling cracking.
The primary goal of AC556 is to ensure that construction joints using expanded metal mesh systems meet minimum performance standards for durability, movement accommodation, and crack control, as outlined in relevant building codes and standards.
