Hindered Settling of Fiber Particles in Viscous Fluids

In the current literature, information can mainly be found about free and hindered settling of isometric particles in Newtonian non-Newtonian fluids. These conclusions cannot used to describe sedimentation non-isometric particle For this reason, we have carried out systematic experiments calculated correlation velocity a cloud high-viscosity pseudoplastic liquid. The were performed transparent model fluids, namely, glycerine (a fluid) an aqueous solution carboxylmethylcelulose CMC pseudo-plastic liquid). fluids similar rheological properties, for example, fresh fine-grained cementitious composites HPC/UHPC. with steel fibers ratio d/l = 0.3/20. was determined fiber volumes from 1% 5%. While it is known previous studies that spherical proportional porosity suspension on exponent 4.8, which confirmed by our verification experiment, studied 22.1. This great increase effect both shape and, particular, mutual influence arises their interweaving connection suspension.
