Why is there an ACI Shotcrete Nozzleman Certification program?
Design engineers wanted a way to ensure that the quality of shotcrete placed on their projects met with their design specifications. The materials are tested in accordance with standards established through the American Concrete Institute (ACI) and ASTM International. Because shotcrete can be affected by the skill of the nozzleman, certain basic requirements should be demonstrated. Designers and engineers with shotcrete experience would design test procedures to assure that the nozzleman had the skill to perform in a satisfactory manor. ACI established a shotcrete nozzleman certification program to establish a basic skill level of shotcrete nozzling. A design engineer could then require the use of ACI nozzleman certification in their specifications. This gives the engineer some confidence in the finished shotcrete product. Who provides ACI certification? Education, testing and certification are provided by sponsoring groups authorized by ACI. The American Shotcrete Association (ASA) is
