ACI 548.15-20 (IN-LB) PDF Download

ACI 548.15-20 (IN-LB) is a standard that provides guidelines for the repair of cracks in concrete using epoxy injection. The specification outlines the use of two-component epoxy-resin adhesive for this purpose. It sets forth the requirements and procedures to ensure effective and durable repair of cracks in concrete structures.

The standard emphasizes the importance of preparing the crack surface before injecting the epoxy resin. This involves cleaning the crack, removing any loose particles or contaminants, and creating a proper groove or opening for the injection. The epoxy resin is then mixed according to the manufacturer's instructions and injected into the crack using appropriate equipment.

ACI 548.15-20 (IN-LB) provides guidelines for the injection process, including the recommended injection pressures, injection ports spacing, and injection intervals. It also specifies the curing time required for the epoxy resin to achieve its full strength. The standard further addresses the testing and evaluation of the repaired cracks to ensure their effectiveness and integrity.
