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

Investigating the Rheological Properties of Ultra High Strength Concrete Made with Various Superplasticizers [PDF]
Ultra-High Strength Concrete (UHSC) is a high-strength and highly ductile material formulated to provide compressive strengths exceeding 130MPa. UHSC materials typically have a very low water-to-cementitious ratio (w/cm), which requires the use of ...

Interparticle forces and superplasticizers in cement suspensions [PDF]
Placing of concrete requires much more water than the cement needs for its hydration. This results in a certain porosity in the hardened concrete, which facilitates chemical degradation of this material.
