Frequently Asked Questions
Is the ACI Field Testing I vocabulary game free?
Yes. The game is free to play with no sign-up. Signing in adds AI explanations for any term.
How does the ACI Field Testing I vocabulary game work?
Each round shows a clue for one of 42 ACI Field Testing I terms. Guess the term in six tries: green means the right letter in the right spot, yellow means the letter is in the term but in another spot, and gray means it is not in the term. After the round, read the explanation and play the next term.
Where do the ACI Field Testing I terms come from?
OpenExamPrep researched each term from the American Concrete Institute (ACI) content outline and primary sources, listed under Sources on this page. The game is independent study material, not an official exam resource.
What is the ACI Concrete Field Testing Technician Grade I certification?
It is the most widely held ACI certification and validates that a technician can perform the seven standard ASTM field tests on freshly mixed concrete: sampling (C172), slump (C143), temperature (C1064), density/unit weight/yield (C138), pressure air content (C231), volumetric air content (C173), and making and curing specimens (C31). The IBC and ACI 318 require Grade I certified technicians to perform acceptance testing of structural concrete on most building projects.
How much does the ACI Grade I exam cost?
ACI does not publish one national exam fee on the official program page. Registration, retake, prep-course, and bundle pricing are set by the local ACI sponsoring group or chapter, while study materials such as the CP-1 41st edition workbook are purchased separately through ACI or a provider.
