The effect of cement modification on the rheological properties of cement paste
Journal of Civil Engineering and Management, 2014 Experimental tests have determined the effect of slag, opoka (silica-calcite sedimentary rock), silica fume (SiO2) suspension, dolomite dust and sodium silicate solution (NaSS) together with the polycarboxylatether based plasticizing admixture on the ...

Polycarboxylate Superplasticizer-Modified Graphene Oxide: Dispersion and Performance Enhancement in Cement Paste [PDF]
NanomaterialsGraphene oxide (GO) significantly enhances cement hydration at the nanoscale; however, its tendency to complex and agglomerate with Ca2⁺ in cement paste remains an unresolved issue.

The Influences of Cement Hydration and Temperature on the Thixotropy of Cement Paste [PDF]
Materials, 2020 The rheological properties of fresh cement paste are highly influenced by a large number of parameters, among which the most important factors are the applied shear stress, and the shear history, the age of the sample and the temperature. The effects of these parameters on the yield stress (designated as structural limit stress in this work), the ...

Onset of Cohesion in Cement Paste [PDF]
Langmuir, 2004 It is generally agreed that the cohesion of cement paste occurs through the formation of a network of nanoparticles of a calcium-silicate-hydrate ("C-S-H"). However, the mechanism by which these particles develop this cohesion has not been established.

Micromechanics of dental cement paste
Journal of the Mechanical Behavior of Biomedical Materials, 2021 Biodentine is a calcium silicate/calcium carbonate/zirconium dioxide/water-based dental replacement biomaterial, significantly outperforming the stiffness and hardness properties of chemically similar construction cement pastes. We here report the first systematic micromechanical investigation of Biodentine, combining grid nanoindentation with ...

Corrosion law of cement paste under hydrogen sulfide conditions in natural gas wells
Frontiers in Materials, 2023 Downhole anticorrosion in sour gas (H2S or CO2) wells is one of the technical problems in petroleum engineering, and the corrosion law of cement paste, which is the “first barrier of the wellbore,” needs to be focused on.

Rheology of lime paste—a comparison with cement paste [PDF]
Rheologica Acta, 2015 The rheological properties of a suspension of lime in water (lime putty) are studied with the help of creep tests in a wide range of deformations including very small values. The results are compared with those obtained with a cement paste and several similarities between the two systems are observed.
