Description
ACI Concrete Field Testing Technician – Grade I
2‑Day Course • 6 CPD Hours Available Upon Request
The ACI Concrete Field Testing Technician Grade I course will benefit all personnel involved in testing fresh concrete. ASTM C31, C94 and ACI 301 all require that technicians making and
curing concrete test specimens for acceptance be certified ACI Concrete Field Testing Technicians.
A working knowledge of the following ASTM standards is contained in this certification program:
- C1064/C1064M—Temperature of Freshly Mixed Hydraulic-Cement Concrete
- C172/C172M—Sampling Freshly Mixed Concrete
- C143/C143M—Slump of Hydraulic-Cement Concrete
- C138/C138M—Density (Unit Weight), Yield, and Air Content (Gravimetric) of Concrete
- C231/C231M—Air Content of Freshly Mixed Concrete by the Pressure Method
- C173/C173M—Air Content of Freshly Mixed Concrete by the Volumetric Method
- C31/C31M—Making and Curing Concrete Test Specimens in the Field
Ohio Concrete professionals conduct the one-day review of the field testing standards and administer the written and performance examinations the following day. The one-hour written examination is closed-book and consists of 55 multiple-choice questions. There are between five and ten questions on each of the standard test methods and 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 practices; AND
- A minimum score of 70% overall.
The performance examination is also “closed book” and requires actual demonstration of six of the required test methods and practices plus a verbal description of Practice C172/C172M
(sampling). The examinee is evaluated on his/her ability to correctly perform (or describe, where allowed) all of the required steps for each procedure.
Examinations are returned and scored by the American Concrete Institute (ACI). Technicians successfully completing both the written and performance examinations will receive a certificate
from ACI. Certification expires in 5 years.
For recertification, ACI requires successful completion of both the performance and written examinations. Individuals may register for “Full Exam Only,” however it is recommended that they
register for the review session to ensure knowledge of the current standards covered on the exam.
