Petrography of mortar and other materials
Contact Us
When mortar issues are of concern, our laboratory is well-versed in investigating historic structures and monuments, as well as new construction.
Petrographic examination can help you:
- Identify cementitious materials and aggregates
- Calculate mortar proportions
- Estimate mortar types: M, S, N or O
- Design tuck pointing mortar
- Perform failure analyses of masonry walls
The ASTM procedure we often refer to is ASTM C1324 “Standard Test Method for Examination and Analysis of Hardened Masonry Mortar”.
Additionally, we may perform petrography on unknown samples associated with various media. This may be useful in identifying unknown deposits or any crystalline contaminant material. Contact us for specific requests.
