Why Ohio homeowners should know it
The American Concrete Institute publishes the codes, standards, and testing certifications that the concrete industry uses to talk about strength, durability, and quality control. ACI certifications such as Concrete Field Testing Technician show that a worker has been tested on the basics of how concrete is sampled and evaluated.
For Ohio homeowners the practical signal is small but real. A concrete contractor whose crew leader holds an ACI certification is more likely to talk in mix-design and slump-test language when explaining a driveway pour — which is the language inspectors use when something goes wrong.
