Many engineering projects require evaluation of masonry materials for determination of structural capacity, specification of restoration and repair materials, and for resolution of building contract disputes. Evaluation includes field and laboratory investigation of the units, mortar, and the masonry assemblage. Nondestructive and semi-destructive test methods are available for the determination of properties of in-place masonry materials, and some of these are standardized. Building codes provide requirements and guidance for the use of testing to determine engineering properties for structural evaluation and for quality assurance. In lieu of testing, guidelines are available for the estimation of material properties. Preservation of masonry buildings involves selecting replacement materials that are compatible in both performance characteristics and appearance. There are a wide variety of methods available for mortar analysis, ranging from simple color and particle gradation matching of aggregates to thorough chemical and petrographic analyses. Recent standardization work has provided useful guidelines for the design of restoration mortars. Determination of the properties of in-use masonry units allows the selection of compatible salvaged units, fabrication of replacement units, and assists in the design of restoration mortars and other materials such as grout. This paper is an abridgment of Chapter 18, "Masonry," in Ratay, Robert T., ed. (2005). Structural Condition Assessment, John Wiley & Sons, Inc., Hoboken, NJ.
