Rheological study of interactions between MHEC and superplasticizers in aqueous solutions for applications in cement industry [PDF]
, 2011 Innovative cement-based materials are characterized today by rather complex formulations. In particular, when cement pastes are considered, their formulation generally includes two different types of polymers: a rheology modifier (RM) (typically a ...

The effect of die spacer on retention and fitting of complete cast crowns
Journal of Craniomaxillofacial Research, 2022 Purpose: Loss of the bracket-tooth bond is one of the most common complaints of patients during orthodontic treatment. Various factors play a role in preventing the loss of such a strong bond between the bracket and tooth, one of which is the ...

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement
Advanced Science, EarlyView.The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...
