T/SCQA 212-2021 Standard for the Construction and Acceptance of Reinforcement of Pre-stressed Carbon Fiber Composite Panels

Scope

Scope: To ensure the technical reliability, safety, economic feasibility, and quality of reinforcing concrete structures with pre-stressed carbon fiber composite panels, this standard is formulated. This standard applies to the construction and acceptance of concrete structures in buildings, bridges, or general structures that use pre-stressed carbon fiber composite panels for reinforcement. When using pre-stressed carbon fiber composite panels for reinforcement, in addition to complying with the provisions of this standard, the following national standards and specifications must also be met: **Main Technical Content**: - **Carbon Fiber Reinforced Polymer Plate**: A board-shaped carbon fiber composite material manufactured by pultrusion using unidirectional continuous carbon fibers as the matrix and epoxy resin. - **Structural Adhesive**: A long-term load-bearing adhesive used for bonding in structural components or structures, referred to as structural adhesive. In civil engineering, based on the limitations of on-site conditions, the structural adhesives used primarily refer to room-temperature curing structural adhesives. - **Room-Temperature Curing**: For unmodified structural adhesives, it refers to the normal chemical reaction process at a temperature not lower than 15°C; for modified structural adhesives, it refers to the normal chemical reaction process at a temperature not lower than 5°C. - **Low-Temperature Curing**: It refers to the normal chemical reaction process at a temperature lower than 5°C. - **Local Damage to Existing Structures**: When reinforcing existing structures with pre-stressed carbon fiber composite panels, it is necessary to avoid adverse effects on the unreinforced parts and related structures, components, or foundation. At the same time, it is necessary to avoid causing local damage to the existing structures that may affect their overall structural performance. - **Installation of Pre-stressed Carbon Fiber Compos
