Commandant's House Mortar Analysis - Washington Navy Yard

Navy Yard, Washington, District of Columbia

Conservators perform basic characterization of one mortar sample to guide recommendations for suitable replacement materials.  Mortar samples will be subjected to standard wet chemical testing (acid digestion, sieve analysis, binder color matching, and aggregate description). This testing is recommended to determine a replication mortar that will be both compatible with the existing masonry (strength, porosity) as well as appropriate in color and texture.  Conservators will prepare one replication mortar samples using local sand to illustrate the recommended formula.
