MCIA’s popular ACI Grade 1 certification program, offered since 1982, covers the ASTM procedures for field testing fresh concrete. The certification is administered by MCIA for the American Concrete Institute and meets criteria set forth in ASTM C94 for technicians who test
fresh concrete for acceptance purposes on any commercial or public works construction where ASTM specifications are cited.
Class 1 certification uses the nationally recognized ACI Concrete Field Testing Technician, Grade 1 program, and any holder of a current certificate with this designation is thus Class 1 certified. No other substitutions are accepted. Technicians needing this certification may include employees of MDOT, testing labs, contractors, consulting design firms, public works agencies, and material suppliers.
The Mississippi Department of Transportation requires this certification for any person conducting concrete field tests on MDOT projects built under QC/QA specifications, and has classified this program as “Class 1” of its “MDOT QC/QA Concrete Technician” certification series.
The ACI Grade 1/MDOT Class 1 course is a two-day program. The first day is dedicated to classroom lectures. Instruction covers various field testing methods and standards. A written examination is given on the morning of the second day, and the program concludes with a field testing practical exam after students complete the written test.
Class 1 covers field testing fresh concrete. The course includes the following procedures:
- Temperature of Freshly Mixed Concrete (ASTM C1064)
- Sampling Freshly Mixed Concrete (ASTM C172)
- Slump of Hydraulic Cement Concrete (ASTM C143)
- Unit Weight, Yield, and Air Content (Gravimetric) of Concrete (ASTM C138)
- Air Content of Freshly Mixed Concrete by the Pressure Method (ASTM C231)
- Air Content of Freshly Mixed Concrete by the Volumetric Method (ASTM C173)
- Making and Curing Concrete Test Specimens in the Field (ASTM C31)
Program details and study materials are mailed to registrants in advance. Students are encouraged to study the pertinent ASTM standards prior to class. Certification candidates should bring the mailed study materials, pencils, erasers, and a calculator to class with them.
The course reviews basic materials regarding concrete testing, and serves to supplement a technician’s general knowledge. It is not, however, appropriate for people without any concrete experience, and will be difficult for anyone without basic math skills and for anyone who does not adequately prepare before classes begin. The program is designed to certify individuals who are experienced and competent in testing concrete for the purpose of quality control. Basic instruction is provided on topics covered by the test, but lectures are not designed to certify individuals who are novices in the industry in only two days.
The closed-book written examination includes individual sections on each of the related ASTM standards and other classroom topics. Students have one hour to complete the test. Passing requires an overall score of at least 70, with no individual section score below 60. Failure on any one section requires retaking all sections of the test. You will have one opportunity to re-test section(s) within 60 days.
Technicians who hold ACI Grade 1/MDOT Class 1 certificates that have expired or are approaching their expiration date may register for the renewal phase of the program. Those who wish to be examined without attending classroom sessions may sit for the written exam and participate in the field testing practical exam that follows.
ACI Grade 1/MDOT Class 1 certification is valid for five years. Renewal requires re-examination in both the written and practical tests.
