Elastic Constants of Grout by Ultrasound

Abstract

Abstract-The deformation of grout is a very important property because of demands that this material is subjected when applied to façades. To set such parameter, compression tests are needed to determine the elasticity modulus or the ultrasound technique might be applied, which is a non-destructive test that allows the determination of the flexibility material matrix and therefore the elastic constants such as longitudinal elasticity modulus (E), transversal elasticity modulus (G) and Poisson's ratio (ν). The aim of this study was to obtain the grout elastic constants with ultrasound tests. For this purpose, we selected three colors and two manufacturers for grout, totaling six samples. The results indicated that the elastic constants determined with ultrasound are equivalent to values obtained for destructive tests.Index Terms-Elasticity modulus, nondestructive test.
