✦ Synopsis


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, da[3 das Zeta-Potential von Zementstein und ZementmSrtel sowohl von chemischen wie auch yon mechanischen Beanspruchungen abh~gt. Zeta-Potential-Messungen krnnen daher dazu benutzt werden den Fortschritt von Korrosion ebsenso festzustellen wie Ver~inderungen in den mechanischen Eigenschaften des Werkstoffs, speziell jedoch Ver~nderungen seiner Biegezugfestigkeit.

The viscosity at an arbitrarily selected shear rate of 1.16 s-1 and the yield stress of anatase dispersions are linearly correlated, and both show a maximum at the isoelectric point (IEP) at pristine conditions. The rheological properties of anatase dispersions respond to the shift in the IEP to hig
