AET Petrography Webinar

Forensic Geology/Petrography: What Aggregate Analyses Tell Us About Concrete

1/26/2022, 11:30 AM - 12:30 PM CST

AET takes you inside an examination of aggregates and concrete to understand the standards, cover typical observations, and review past projects.

We’ll also answer these questions and many others:

  • Does AET use XRD?
  • Are there methods for detecting problem minerals (like pyrrhotite) using GIS?
  • Can deleterious materials in aggregates lead to court cases?
  • Besides the ASTM standards, what other references does AET recommend for aspiring material petrographers?
