- Petrography - Wikipedia
Petrography is a branch of petrology that focuses on detailed descriptions of rocks Someone who studies petrography is called a petrographer The mineral content and the textural relationships within the rock are described in detail The classification of rocks is based on the information acquired during the petrographic analysis
- What is Petrography? Applications for Concrete . . . - Concrete Science
A petrographic examination will determine what is “going on” with the construction material A petrographer examines the concrete and assesses volumetric proportions and characteristics of the concrete to see how compatible the products are together that create this “man-made rock”

- Petrographic Analysis - SpringerLink
Petrography is the description and systematic classification of rocks, mainly by the microscopic examination of thin sections Petrographic analysis identifies the origin, whether igneous, sedimentary, or metamorphic, and the mineral content for the classification of a rock
- Petrographic Examination of Concrete - Concrete Research Testing, LLC
Petrographic examinations of concrete are typically performed due to the premature failure of an existing concrete structure or a problem during a construction project A petrographer is retained to determine the cause of the problem and often to determine who is responsible
