ACI 364.8T-02 (R2011) PDF Download

ACI 364.8T-02 (R2011) is a TechNote from the American Concrete Institute (ACI) that provides guidance on the use of hydro demolition for concrete removal in unbonded post-tensioned systems. This standard is a committee document that has been reviewed and approved by ACI's Technical Activities Committee.

The standard is aimed at providing specific directions and recommendations on the issue of concrete removal in unbonded post-tensioned systems using hydro demolition techniques. It is a practice-oriented document that focuses on the use of hydro demolition as a means of safely and efficiently removing concrete without damaging the post-tensioning system.

The standard is likely to provide information on the recommended equipment, techniques, and safety protocols for conducting hydro demolition in unbonded post-tensioned systems. This may include considerations such as water pressure, nozzle design, distance from the concrete surface, and proper protection of the post-tensioning tendons during the process.
