Shotcrete Nozzleman and Nozzleman-in-Training - Dry-Mix Process
دوره تکنیسین شاتکریت خشک
An ACI-certified Shotcrete Nozzleman (Dry-Mix Process) is an individual who has demonstrated knowledge of the dry-mix shotcrete process (via written examination) and the ability to properly place dry-mix shotcrete (via performance examination shooting a limited-size test panel). The Shotcrete Nozzleman (Dry-Mix Process) also possesses substantially more shotcrete work experience in actual dry-mix shotcrete field applications than a Shotcrete-Nozzleman-in-Training (Dry-Mix Process).
An ACI-certified Shotcrete Nozzleman-in-Training (Dry-Mix Process) is an individual who has demonstrated knowledge of the dry-mix shotcrete process (via written examination) and the ability to properly place dry-mix shotcrete (via performance examination shooting a limited-size test panel) but possesses substantially less shotcrete work experience than an ACI-certified Shotcrete Nozzleman (Dry-Mix Process). Sponsoring Groups are currently offering Nozzleman-in-Training certifications for Vertical orientation.
Scope and Knowledge:
The primary technical resource for this program is the ACI CCS-4 document, “Concrete Craftsman Series: Shotcrete for the Craftsman.”
The program requires knowledge in the following areas of shotcrete construction:
- Basic concrete technology,
- Shotcrete Equipment,
- Environmental conditions and precautions,
- Inspection and preparation of surfaces,
- Shotcrete placement, principles, and techniques,
- Finishing and tolerance controls,
- Testing/quality, and
No specific education is required as a prerequisite for Shotcrete Nozzleman-in-Training or Shotcrete Nozzleman certification. A minimum of 25 hours of verified shotcrete work experience is a prerequisite to participate in the performance examination, and to be eligible for certification as a Shotcrete Nozzleman-in-Training. A minimum of 500 hours of verified shotcrete work experience is required to be eligible for full Shotcrete Nozzleman certification. An ACI-certified Shotcrete Nozzleman-in-Training may upgrade to full Shotcrete Nozzleman certification for the remainder of their original certification period following submission and verification of documentation reflecting 475 additional hours of shotcrete work experience.
