Timedependent rheological behaviour of cemented backfill

AbstractWhen cemented backfill mixture (CBM) is transported through pipelines from a backfill plant to stopes, it experiences shearing forces over the transport time. In this paper, the effects of solids concentration, binder content, shear rate and curing time on the timedependent rheological behaviour of CBM were studied. It was found that over long periods of shearing at a constant rate
