NDT of Cementitious Materials

Abstract

The US method presented an automatically extract certain parameters of US waves, parameters that have been continuously recorded during the mortar hardening process. Until now, the standard methodes measured only one parameter, at certain stiffness stages. This method presents the material behaviour variation that depends on the hydration and on the elastic properties of mortar materials. In this way we have a visual of the hardening process, which was not available untill now. From now on this method can be used for applications in industrial laboratories.
