Masonry 101 #6: Masonry Assemblies

This lesson looks at the properties of masonry assemblies based on the how it is constructed and bonded. Structural assembly properties including the modulus of elasticity, modulus of rupture, and compressive strength will be introduced and discussed. Other assembly properties related to dimensional stability, fire resistance and energy performance will also be reviewed, along with resources that can be used for additional information on these topics.…

Nondestructive Evaluation and Testing of Masonry

Nondestructive evaluation methods are valuable approaches for evaluating conditions of existing masonry construction without causing damage. Masonry strength can also be measured in place using in situ test methods, without resorting to destructive sample removal for laboratory testing. Methods discussed during this lesson include mortar hardness testing, pulse velocity measurements, surface penetrating radar, infrared thermography, flatjack testing, and in situ shear tests, with special emphasis on applying these methods for diagnosing both historic and modern masonry construction.…
