Yield stress of aerated cement paste
Blandine Feneuil, Nicolas Roussel, Olivier Pitois
Yield stress of aerated cement paste is studied. Samples are prepared by mixing aqueous foam with cement paste, which allows controlling bubble size, gas volume fraction and yield…

Optimal cement paste yield stress for the production of stable cement foams
Blandine Feneuil, Nicolas Roussel, Olivier Pitois
Production of morphology-controlled cement foams remains challenging, mainly due to bubble stability issues during cement setting. The use of cement paste with high yield stress is…

Stability criterion for fresh cement foams
Blandine Feneuil, Patrick Aimedieu, Mario Scheel +3
We prepare and study cement foam samples with well-controlled structure, i.e. containing monodisperse bubbles. We observe that the foam structure often changes before cement settin…
