What Is an ACI Field Technician Grade 1?
An ACI Field Technician Grade 1 is a concrete testing professional certified by the American Concrete Institute to perform field testing and sampling of freshly mixed concrete. Certification demonstrates that the technician understands proper testing procedures and follows nationally recognized standards.
These services are commonly required on projects involving:
- Foundations
- Footings
- Slabs-on-grade
- Structural walls
- Columns
- Elevated decks
- Parking structures
- Commercial buildings
- Multi-family developments
- Public infrastructure
Proper testing helps verify that concrete delivered to the project matches the approved mix design and project specifications.

Slump Testing
Slump testing measures the consistency and workability of freshly mixed concrete before placement. This simple but important test helps determine whether the concrete contains the proper amount of water and whether the mixture remains suitable for installation.
Our technicians perform slump testing according to ASTM requirements before concrete placement begins. If the results fall outside project specifications, contractors can address the issue immediately before the concrete is placed.
Concrete Temperature Testing
Concrete temperature directly affects curing, strength development, and long-term performance. Temperatures that are too high or too low can reduce concrete quality and increase the likelihood of cracking.
Our inspectors verify the temperature of freshly mixed concrete at the job site to confirm compliance with project specifications and applicable standards.
Air Content Testing
Entrained air plays an important role in concrete durability, especially when concrete may experience moisture or freeze-thaw conditions. Our certified technicians perform air content testing to verify that the concrete mixture contains the proper amount of entrained air before placement.
Accurate air content testing helps improve durability while reducing the risk of future deterioration.
Unit Weight Testing
Unit weight testing measures the density and yield of freshly mixed concrete. This information helps verify that the concrete mixture meets the approved design and provides additional quality control during placement.
Our technicians complete these tests according to ASTM procedures and document the results for your project records.
Concrete Test Cylinders
Concrete test cylinders provide one of the most important methods for verifying compressive strength. During placement, our technicians prepare representative 4-inch by 8-inch or 6-inch by 12-inch concrete cylinders following ACI and ASTM standards.
Each cylinder is carefully molded, identified, protected, and stored according to project requirements. After the required initial curing period, the samples are transported to an approved laboratory for compressive strength testing.
Accurate cylinder preparation is essential because improper handling can produce misleading strength results that may delay construction or require additional engineering review.
Why Concrete Test Cylinders Matter
Many contractors and property owners underestimate the importance of concrete cylinder testing. However, these samples provide valuable information that engineers and building officials use to evaluate structural performance.
Concrete cylinders help verify:
- Compressive strength
- Concrete quality
- Proper curing
- Compliance with approved mix designs
- Structural performance
- Project acceptance requirements
Without representative samples, it becomes difficult to confirm that the installed concrete meets the specified design strength.
Understanding the Slump Test
The slump test is one of the most common field tests performed during concrete placement. This test measures the consistency of freshly mixed concrete before it hardens.
A proper slump test helps determine whether:
- The concrete contains the correct amount of water.
- The mixture remains workable.
- Concrete consistency matches previous truckloads.
- Additional water has altered the approved mix.
- The concrete is suitable for placement.
Because consistency directly affects strength and durability, slump testing provides valuable quality control throughout the concrete placement process.
Flow Testing for Self-Consolidating Concrete
Some projects use self-consolidating concrete (SCC), which requires flow testing rather than a traditional slump test. Flow testing measures how freely highly workable concrete spreads after the slump cone is removed.
This testing method helps verify that self-consolidating concrete maintains the proper flow characteristics without excessive segregation or material separation.
Our technicians perform the appropriate test based on the concrete specified for your project.
