Numerical Reliability Study Based on Rheological Input for Bingham Paste Pumping Using a Finite Volume Approach in OpenFOAM.

Rheological quantification is important in many industries, the concrete industry in particular, e.g., pumping, form filling, etc.

Effect of Ca(OH) Addition on the Engineering Properties of Sodium Sulfate Activated Slag.

Alkali-activated slag is considered as a sustainable construction material due to its environmentally friendly nature. To further promote the sustainable nature of alkali-activated slag, a sodium sulfate activator is suggested to be used since it can be obtained naturally and generates lower greenhouse gas emissions. However, the mixtures activated by sodium sulfate exhibit low early strength and very long setting times.

Rheological Properties of Cement Paste with Nano-FeO under Magnetic Field: Flow Curve and Nanoparticle Agglomeration.

Understanding the influence of magnetic fields on the rheological behavior of flowing cement paste is of great importance to achieve active rheology control during concrete pumping. In this study, the rheological properties of cementitious paste with water-to-cement (w/c) ratio of 0.4 and nano-FeO content of 3% are first measured under magnetic field.
