Impact de l'architecture macromoléculaire des polymères sur les propriétés physico-chimiques des coulis de ciment

Abstract : The implementation of cement materials is improved by addition of polymer as called superplasticizer. In this study, we look for the impact of the polymer architecture on the physico-chemistry properties of cement slurries. At first, we focused on the synthesis ad characterization of sodium polymethacrylates grafted by poly(ethylene oxide) chains. Then, we observe the adsorption of these superplasticizers on different types of cement using macroscopic and microscopic techniques. Finally, we measure the setting time, the behavior at rest and the fluidity of different cement slurries with the use of new tools such as the helicoidal ribbon geometry and the ultrasound technique.
