Using Coupled Rheometer-FBRM to Study Rheological Properties and Microstructure of Cemented Paste Backfill

open access: yesAdvances in Materials Science and Engineering, 2019
Rheological properties, such as the yield stress, viscosity, and thixotropy, are related to the microstructure of cemented paste backfill (CPB). To highlight the relationship, two instruments were combined to measure the changes in the microstructure and

Initial rheological description of high performance concretes

open access: yesMaterials Research, 2006
Concrete is defined as a composite material and, in rheological terms, it can be understood as a concentrated suspension of solid particles (aggregates) in a viscous liquid (cement paste). On a macroscopic scale, concrete flows as a liquid.

Effect of Rheological Mesoparameters on Shear Mechanical Behavior of Joints

open access: yesGeofluids, 2022
Under natural conditions, joint failure usually occurs after long-term loading rather than short-term loading. In order to prevent rock mass failure caused by creep behavior, bolt is widely used as a mature and effective reinforcement method.

Rheological Behavior Models of Polymers

open access: yesBiointerface Research in Applied Chemistry, 2021
We studied and investigated the various viscosimetric and rheological polymers' behaviors during this comprehensive review. The viscosities relate to the investigation of the flux, the deformation, and the polymers' elasticity; we have employed the viscosity since this plays a primordial role in the phenomena flux and implementation of the polymer. The

Effect of cement fineness and polycarboxylate dosage on the rheological and mechanical behavior of a mortar

open access: yesMATEC Web of Conferences, 2018
The use of certain organic additives in the production of mortar and concrete influences the workability and the hydration kinetic of mortar. This results in a modification of some properties, namely rheological behavior and mechanical strength.

Mechanism of bubble action in backfill slurry and the evolution of its rheological properties

open access: yesMeitan xuebao
Cemented paste backfill is a suspension composed of solid-liquid-gas three-phase. For a long time, the focus has been mostly on the rheological behavior of solid-liquid two-phase, while the effect of gas phase on slurry with complex rheological behavior ...
