A CSA-Based Concrete Field Testing Technician—Grade I is an individual who has demonstrated the knowledge and ability to properly perform and record the results of seven basic field test methods and standard practices on freshly-mixed concrete as prescribed by Canadian Standards Association methods.
Scope and Knowledge:
The program requires a working knowledge of the following CSA test methods and standard practices:
- A23.2–1C—Sampling Plastic Concrete
- A23.2–5C—Slump of Concrete
- A23.2–6C—Density, Yield, and Cementing Materials Factor of Plastic Concrete
- A23.2–4C—Air Content of Plastic Concrete by the Pressure Method
- A23.2–7C—Air Content of Plastic Concrete by the Volumetric Method (written exam only)
- A23.2–3C—Making and Curing Concrete Compression and Flexural Test Specimens
- A23.2–17C—Temperature of Freshly Mixed Hydraulic Cement Concrete
ACI will grant certification only to those applicants who meet both of the following requirements:
- A passing grade on the ACI written examination; AND
- Successful completion of the ACI performance examination.
The one-hour written examination is closed-book and consists of 56 multiple-choice questions. There are eight questions on each of the test methods and standard practices.
To pass the written examination, both of the following conditions must be met:
- At least 60% correct for each of the required test methods and standard practices; AND
- A minimum score of 70% overall.
The performance examination is also closed-book and requires actual demonstration of five of the required CSA test methods and standard practices plus a verbal description of Standard Practice A23.2–1C (sampling). The examinee is judged on his/her ability to correctly perform or describe all of the required procedures for each test method and standard practice.
Certification is valid for a period of five years from the date of successfully completing all requirements.
Recertification requires successful completion of both the written and performance examinations.
