Correlation between zeta-potential and mechanical properties for cementitious materials

It is shown experimentally that the zeta-potential of cement pastes and cement mortars depends on both the chemical and the mechanical stresses acting on the material. Zeta-potential measurements may thus be used to detect the progress of corrosion as well as a change in mechanical properties of the...

Description
Summary:It is shown experimentally that the zeta-potential of cement pastes and cement mortars depends on both the chemical and the mechanical stresses acting on the material. Zeta-potential measurements may thus be used to detect the progress of corrosion as well as a change in mechanical properties of the material, especially its flexural strength. Es wird durch experimentelle Untersuchungen nachgewiesen, daβ das Zeta-Potential von Zemenstein und Zementmörtel sowohl von chemischen wie auch von mechanischen Beanspruchungen abhängt. Zeta-Potential-Messungen können daher dazu benutzt werden den Fortschritt von Korrosion ebsenso festzustellen wie Veränderungen in den mechanischen Eigenschaften des Werkstoffs, speziell jedoch Veränderungen seiner Biegezugfestigkeit.
