GET A QUOTEJan 29, 2019 · A well-distributed fiber can actually reduce pressures to some degree, largely due to the more uniform nature of the resulting concrete mix caused by the fiber suspension of fine and coarse aggregates. Pumping: grate flow. Fibers can complicate concrete flow through a conventional slatted pump grate, especially at elevated dosages.

GET A QUOTEJan 28, 2020 · Pumping Fibers When it comes to fiber-reinforced concrete, synthetic and steel fibers typically don't decrease pumpability, but they can impact how fast one can pump. And, as Lloyd points out, macro-synthetic fiber can collect on the hopper grate. "It's important to modify your standard grate to a round and smooth grate," he says.
