10.007 Concrete Strength Tester
| Q | My laboratory has ACI Concrete Laboratory Testing Technicians – Grade 1. Recently, we were informed by ACI that we should be using ACI Concrete Strength Testing Technicians to break concrete. This does not seem correct since the tests for the strength tester are also in the Grade 1. Please advise?

The ACI Concrete Laboratory Testing Technician – Grade 1 certification includes capping and testing concrete cylinder specimens for compressive strength, but does not include flexural strength testing. Certification for this test may be obtained by the Concrete Strength Testing Technician or Concrete Laboratory Testing Technician – Grade 2 certifications. If certification for performing only compression tests is required, the Concrete Laboratory Testing Technician – Grade 1 certification should be sufficient. |
