Correlating cement characteristics with rheology of paste

Cement: A two thousand year old nano-colloid

“…The effect of SPs on the hydration of Portland cement paste has been extensively studied, almost completely from an applicative point of view [32,33,35,36].…”

Avoiding inaccurate interpretations of rheological measurements for cement-based materials

“…1). Furthermore, even the cement properties, which show some variation slightly alter due to the complexity of the production process, can in some cases significantly affect the fresh properties of cement-based materials [22][23][24][25][26][27]. Examples are known of variations in yield stress and plastic viscosity, and their evolution in time, with Cement and Concrete Research xxx (2015) xxx-xxx cement date are illustrated in Fig.…”

A Sustainable Graphene Based Cement Composite

“…By considering these factors, the relationship between viscosity trend and the shear rate of the flow curve can be determined [9]. Based on power rate index values "n", it also provides the information about the shear deformation, i.e., shear thickening (n > 1) or shear thinning (n < 1) [7] The consistency (K) has no physical meaning and difficult to compare because of its dimension (Pa.s n ) which is dependent on "n" [34]. Wang et al [7] studied the shear deformation for graphene oxide in cement paste and found that cement paste curve can be divided into shear thinning and shear thickening stage based on the inflection point.…”
