This course is for all personnel involved in testing fresh concrete. ASTM C94 and ACI 301 require technicians to have demonstrated an ability equivalent to ACI Concrete Field-Testing Technician-Grade I certification.

A half day review, with exams administered the following day, is sponsored by OCAPA in cooperation with the American Concrete Institute (ACI). It is conducted by a certified examiner and graded by ACI.

Those successfully completing both the ACI written and performance examinations will receive a wallet card from ACI certifying them as an ACI Concrete Field-Testing Technician – Grade I. Certification is valid for 5 years.

Required Prior Knowledge:

• Familiarity with basic algebra.
• A working knowledge of the following ASTM Standards:
  • C 172 – Sampling Freshly Mixed Concrete
  • C 1064 -Temperature of Freshly Mixed Portland Cement Concrete
  • C 143 – Slump of Hydraulic Cement Concrete
  • C 138 -Unit Weight, Yield, and Air Content of Concrete
  • C 231 – Air Content of Freshly Mixed Concrete by the Pressure Method
  • C 173 – Air Content of Freshly Mixed Concrete by the Volumetric Method
  • C 31 – Making and Curing Concrete Test Specimens in the Field
• You must be familiar with your testing equipment and be able to proceed through testing procedures without coaching or comment from the examiner or others.
• Students must provide their own equipment or arrange to share equipment.

No more than two students per equipment set.

Notice to Students Re-Certifying or Challenging:

• You must provide your previous ACI # on the registration form.
