Abstract:The implementation of cement materials is improved by the addition of a
polymer called a superplasticizer. In this presentation, we look for the impact of the polymer architecture on the physico-chemistry properties of cement slurries. Initially, we focus on the adsorption of sodium polymethacrylate grafted by poly(ethylene oxide) chains on different types of cement using macroscopic and microscopic techniques. Finally, we measure the fluidity of different cement slurries with the use of new tools such as helicoidal ribbon geometry to explain how polymer architecture controls the performance concrete formulations.
