Concrete Strength Testing Technician
OVERVIEW
A Concrete Strength Testing Technician is an individual who has demonstrated 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.
Note: To become ACI Concrete Laboratory Testing Technician Level I certified you must obtain both the ACI Concrete Strength Testing Technician and the Aggregate Testing Technician Level I certifications.
SCOPE AND KNOWLEDGE
The program requires a working knowledge of the following ASTM test methods and practices:
-
C617/C617M—Capping Cylindrical Concrete Specimens
-
C1231/C1231M—Unbonded Caps for Concrete Cylinders
-
C39/C39M—Compressive Strength of Cylindrical Concrete Specimens
-
C78/C78M—Flexural Strength of Concrete
CERTIFICATION REQUIREMENTS
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 approximately 40 multiple-choice questions. There are at least eight questions on each of the practices and test methods.
To pass the written examination, both of the following conditions must be met:
-
At least 60% correct for each of the required practices and test methods, and
-
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 all of the required steps for each procedure.
Recertification is necessary every five years and requires successful completion of both the written and performance examinations.
RECORDING DEVICES
ALL cell phones and other recording devices such as Smart Glasses (Meta, Google, Apple, Samsung, Snap, XREAL, Rokid, Viture, RayNeo, Vizix, Microsoft, Epson RealWear, etc.) are NOT allowed to be accessed/worn during any ACI Examination. All such devices must either be surrendered to the examiner for return following the exam or stowed out of arm's reach during the examination and set to silent (in the case of cell phones).
NO WEAPONS
No weapons are permitted at any ACI Certification session.
AMERICANS WITH DISABILITY ACT
Individuals requesting special accommodations enabling them to participate in ACI certification examinations must submit a letter from their primary physician to the Kansas Chapter ACI describing the physical challenge and providing a proposed solution (i.e. more time, a reader for the questions, physical assistance, etc.). The Kansas Chapter ACI will forward the request and physician’s letter to ACI for direction. Since the notification and formulation of appropriate accommodations takes time, candidates must make their request and submit the physician letter to the Kansas Chapter ACI at least three weeks prior to a certification examination session to formulate appropriate accommodations, arrange for their availability at the session, and accept the registration.
