Rheological study of interactions between MHEC and superplasticizers in aqueous solutions for applications in cement industry [PDF]

open access: yes, 2011
Innovative cement-based materials are characterized today by rather complex formulations. In particular, when cement pastes are considered, their formulation generally includes two different types of polymers: a rheology modifier (RM) (typically a ...

Comparative Study of Soil Grouting with Cement Slurry and Cement-Sodium Silicate Slurry

open access: yesAdvances in Materials Science and Engineering, 2018
Cement slurry and cement-sodium silicate slurry are most widely applied for soil grouting reinforcement project. The viscosity change of cement slurry is negligible during grouting period and presumed to be time independent, while the viscosity of cement-
