NMR and Rheometrical study of Lime-Cement pastes

Contrary to cement, which is widely studied, only few studies concentrate on lime-cement mixes, and even less discuss the effect of lime on cement setting. As these new materials appears increasingly in the industry, it is necessary to better understand the effect of hydrated lime on the setting of cement. In this study, we followed the setting of different lime-cement mixtures by Nuclear Magnetic Resonance (NMR), which provide information on the porous structure, and by rheometry to monitor the elastic modulus. The correlation of these two methods clearly reveals the successive steps of setting and the significant impact of hydrated lime.
