Historic Mortar Testing, Analysis, and Matching

AMR Labs provides historic mortar analysis to identify historic lime and the composition formula of historic mortar through a detailed mortar analysis.

Historic Lime Mortar Matching Analysis

We test old historic mortars to identify historic lime and the composition formula of historic mortar through mortar analysis. By analyzing samples of old mortar, we can determine the composition of the samples even if they are crumbled. While historic mortars contain historic lime, they often have other portions to their composition.

During our analysis of historic mortar compositions, we analyze the sand, plant and animal fibers/hair, lime, Portland, sealers, contaminants, and pigments. You will receive a detailed mortar analysis report and formula for replicating the historic mortar, and recommendations that may be relevant. If you need other information about the mortar being tested, be sure to include it in your notes to us.

If you have questions about mortar analysis, historic lime, our testing process, or special testing requirements, please call or email us.

Historic Lime Mortar Analysis


Mortar Testing

Historic Mortar Analysis
This test follows the astm testing methods for testing hardened mortar samples including historic lime mortars. This is a complete mortar analysis and includes the following mortar testing methods and more.

Crushing pressure analysis of the mortar compressive strength, chemical or acid digestion test of mortar, composition testing of mortar samples, among other combined mortar testing methods.

Through this mortar analysis, we identify and determine if the mortar is a historic mortar containing historic lime, the mortar composition, color and gradation of sand used, ratio of sand and cement binders, and produce a matching mortar formula to the existing mortar. We can also compare samples of mortar tested to confirm if the mortars are of the same composition.

Mortar Matching

Historic Mortar Matching
In this analysis of existing mortar samples, we test the mortar composition, color and graded particles of the sand, pigments, and compressive strength to determine the mortar formula for matching the old mortar.

This mortar formula is then tested, adjusted, and confirmed to match the existing mortar color for a complete mortar match of the formula, color and composition. This test is commonly used by masonry repair contractors and homeowners looking for diy methods of brick repair to make it easy and accurate, and is used for producing custom bags of mortar.

Brick Testing

Masonry Unit Testing
When choosing the right mortar for a masonry structure, or determining if the mortar used is a good mortar, you need to test the crushing pressure or compressive strength of the masonry units or mortar samples.

This would be the brick, block, stone, or tiles. Mortar should be slightly softer than the masonry units being installed to prevent damage to the masonry units. This test determines the crushing pressure of masonry units or can test the crushing pressure of the mortar sample. For full details about the mortar, select the mortar testing option above and get a complete mortar testing analysis report.

Quick Mortar Match
Match mortar color fast with the quick mortar match. This test bases the mortar composition on general mortar type formulas and the compressive strength of your existing mortar.

Requires two or more pieces of surface mortar, but crumbled mortar is ok too.
