Visit ACI's site to verify and individual's certification.
A Concrete Strength Testing Technician is an individual who can demonstrate the knowledge and ability to properly perform, record, and report the results of four basic laboratory procedures related to the determination of concrete compressive and flexural strength.
Scope and Knowledge
The program requires a working knowledge of the following ASTM practices and test methods:
- C617 - Capping Cylindrical Concrete Specimens
- C1231/C1231M - Unbonded Caps for Concrete Cylinders
- C39/C39M - Compressive Strength of Cylindrical Concrete Specimens
- C78 - Flexural Strength of Concrete
ACI will grant certification to those who meet both of the following requirements:
- A passing grade on the ACI written examination
- Successful completion of the ACI performance exam
The one-hour written examination is closed-book and consists of approximately 40 multiple choice questions. There are at least 8 questions on each of the practices and test methods. To pass the written exam, both of the following conditions must be met:
- At least 60% correct for each of the required practices and test methods
- A minimum score of 70% overall
The performance examination is also closed-book and requires actual demonstration of the required practices and test methods. The examinee is judged on his/her ability to correctly perform or describe all of the required procedures for each standard.
Recertification is every five years.
