Masonry Field Testing and Laboratory Testing


The ACI Certification process is rigorous, and those taking the examinations should be familiar with the testing requirements as noted at

The Education Review Sessions are excellent ways for new technicians, contractors, producers, and engineers to learn about masonry test procedures, their basis, and proper ways to sample and test masonry materials. They also serve as an excellent way for experienced testing technicians to prepare for the Certification Examinations. They will not however, be effective in teaching someone relatively new to masonry to be immediately ready to take the ACI Certification Examinations.

For the review sessions, instructors will review typical tests for masonry units, mortar, grout and assemblies, including ASTM C140, C780, C1019, and C1314, and other important procedures, as well as those addressed by the ACI Certification Examinations. After the classroom portion of the Review Sessions, a practical hands-on session will be offered so that attendees can observe, and in some cases try their hands at, specimen preparation and masonry testing.

Approximate times are 8:00 AM – 4:00 PM for the review session and 7:30 AM – 4:00 PM for the certification examination.

Session will be hosted at Nelson Testing Laboratories at 717 Industrial Drive, Elmhurst, Illinois 60126.

  • Sampling & Testing CMU per ASTM C140
