ACI Concrete Strength Test Certification


2023/2024 ACI concrete strength TESTING TECHNICIAN (csT)


Please review the class schedule and recommendations below.

  1. The class will begin at 8:30 am and will end at 4:00 pm on day one.
  2. This is a certification course and not a complete training class. Students are expected to be familiar with the course material and how to perform the tests before arriving at the certification course. If the student is not able to self-prepare or practice the test methods, we highly encourage completing ACI’s eLearning program (additional separate cost). Here is the link:

    On-Demand Course: Concrete Strength Testing Technician Certification Training
  3. The first day of class will be a review of the 4 ASTM test methods followed by a laboratory practice session.
  4. Come prepared to test concrete – safety boots or shoes, clothes that you don’t mind getting concrete on, safety glasses if you want. Gloves will be provided, but feel free to bring your own.
  5. The CST sessions will be limited to 12 students.
  6. The MCA will be providing disposable masks and gloves to each student for those who choose to use them.
  7. Each student will receive their classroom materials including the ACI Concrete Strength Testing Certification manual 2 weeks before the exam.
  8. Day 2 will be the written and practical exam.
  9. Lunch will be provided for day 1. Pre-packaged snacks and beverages will be available.

PLEASE NOTE - YOU ARE NOT REQUIRED TO HAVE AN ACI CONCRETE STRENGTH TESTING CERTIFICATION TO BREAK BEAMS ON A PORTABLE BEAM BREAKER FOR OPEN TO TRAFFIC. THIS CERTIFICATION IS FOR LAB TECHNICIANS THAT NEED TO COMPLY WITH ASTM 1077 OR AASHTO LAB REQUIREMENTS FOR PERFORMING STRENGTH TESTS FOR ACCEPTANCE.

COURSE OVERVIEW

Introduced by ACI in 1997, the Concrete Strength Testing (CST) certification was developed to certify laboratory technicians in the capping and breaking of cylinders and breaking of beams.

Certification assures owners, specifiers, and other interested parties that the testing of strength specimens is conducted by qualified laboratory personnel.

The course covers the following ASTM test methods:
C617- Capping Cylindrical Test Specimens  |  C1231 - Use of Unbonded Caps in the Determination of Compressive Strength  |  C39 - Compressive Strength of Cylindrical Concrete Specimens  |  C78- Flexural Strength of Concrete

On day one, the four ASTM standards are reviewed through a combination of classroom and laboratory instruction. On day two, students complete written and performance exams by demonstrating their knowledge of the test methods. The CST certification meets the requirements for ASTM C94 “Standard Specification for Ready Mix Concrete”, ASTM C1077 “Standard Practice for Laboratories Testing Concrete and Concrete Aggregates for use in Construction” and MDOT’s QA/QC Laboratory Technician Quality Program.
 

EXAM

The “closed book” written exam consists of 40 multiple-choice questions divided into four sections. Each section covers an individual ASTM Standard. Passing requires a minimum overall score of 70% AND a minimum score of 60% on each individual standard. Students have 60 minutes to complete the written exam. 

For the performance exam, students are evaluated on their ability to correctly perform the required procedures for each of the ASTM standards.

NOTE: Students successfully passing both the ACI CST and ACI ATT certifications will also receive ACI’s Laboratory Testing Technician – Grade I Certification.
