Abstract: Recent advances in nondestructive testing technology have lead to mainstream use of several methods for evaluating masonry construction. Nondestructive approaches such as rebound hardness, stress wave transmission, impact-echo, surface penetrating radar, tomographic imaging, and infrared thermography are useful for qualitative condition surveys as well as identification of internal features such as voids or areas of distress. In situ test methods are also available for determination of engineering properties. Flatjack methods are used to measure the state of compressive stress and compression response. Masonry bed joint shear stress may be evaluated using an in situ shear test, and mortar-unit bond strength is tested using an adaptation of the bond wrench approach. Standardized methods exist for many of the evaluation approaches and efforts to develop additional testing standards are ongoing with committees of ASTM and RILEM.
