Structural, dielectric and piezoelectric study of Ca-, Zr-modified BaTiO3 lead-free ceramics

H Msouni, Amina Tachafine, M El Aatmani, Didier Fasquelle, Jean-Claude Carru, M El Hammioui, Mohamed Rguiti, A Zegzouti, A Outzourhit, M Daoud

We prepared a lead-free ceramic (Ba0.85 Ca0.15)(Ti1−x Zrx )O3 (BCTZ) using the conventional mixed oxide technique. The samples were prepared by an ordinary mixing and sintering technique. In this study we investigated how small amounts of Zr 4+ can affect the crystal structure and microstructure as...

On shrinkage and structure changes of pure and blended Portland concretes

Yao Zhang, Catherine A. Davy, Grégory Tricot, Cyrille Albert-Mercier, Natacha Henry, Pieter Bertier, Fréderic Cazaux, Denis Damidot, Xavier Bourbon

This research investigates the long-term shrinkage and Relative Mass Loss (RML) of mature Portland concretes (pure CEMI and blended CEMV/A), at temperatures of 20°C and 80°C. When placed at 80°C and at relative humidities (RH) below 50-60%, concrete shrinkage increases with very slow stabilization...
