The ducts were air pressure tested to ensure the duct can successfully be grouted for a bonded post-tensioned system. During the air pressure testing, tendon stressing and grouting, web cracks form that cause delamination of the concrete in the web that lead to repairs.Allen, Brett M...
1.1 Purpose. Demonstrate the durability of a flexible air duct assembly (low pressure side for turbocharger applications) in the air induction system. This test subjects the duct to the full range of temperature and relative movement in the underhood environment from -35 °C to the Excursion ...
