Rheological Properties of Cemented Paste Backfill with

This study investigates the time-dependent rheological behavior of cemented paste backfill (CPB) that contains alkali-activated slag (AAS) as a binder. Rheological measurements with the controlled shear strain method have been conducted on various AAS-CPB samples with different binder contents, silicate modulus (Ms: SiO2/Na2O molar ratio), fineness of slag and curing temperatures. The Bingham model afforded a good fit to all of the CPB mixtures. The results show that AAS-CPB

Using Coupled Rheometer-FBRM to Study Rheological

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 the rheological properties of CPB simultaneously. In this way, the particle/agglomerate size distribution characterized by the focused

Rheological behavior of ultrafine-tailings cemented

30.08.2020· The experimental equipment for rheological testing consisted of two parts: a temperature controller and a rheometer. The rheometer (HAAKE VTIQ), with 200 μN·m minimum torque and a four-bladed paddle rotor (FL 22 4B/SS-01140879), was used to test the rheological behavior of the UCPB. A water bath thermostat was used to keep the preheated materials and the UCPB at the same

CPB tech-nology excels in tailings utilization and the strength of filling body and is widely used in metal mines and coal mines[8,9]. Although the CPB

A simple L-shape pipe flow test for practical rheological

01.11.2019· Cemented high-density or paste backfill is commonly used in underground mines. The slurry is pumped or gravity-fed into the stope through a pipeline. The pipe flow is completely dominated by its rheological properties. For practical applications, a complicated and expensive flow loop test is generally required to determine the industrial rheological properties. To find a more easily applied, alternative

Maxon equipment applications include; processing tailings from mining operation; paste treatment and backfill applications for underground hard rock mines; remediation of existing and closed mine tailing ponds; and tailing processing for coal fired power plants. Equipment includes single and twin shaft mixers, remixers and agitators for processing and placement of thickened tailings or paste. Maxon

Contribution to Laboratorial Determination of Rheological

Rheometers and viscometers are pieces of equipment for directly measuring of the relationship between shear rate and shear stress or apparent viscosity, which characterises the slurry rheology (He et al, 2004). Viscometers measure the viscosity and flow properties of a fluid at a particular shear rate.
