Steel fibres are commonly used in the refractory industry to
reinforce high temperature concretes, though limited information is
available on the mechanical properties of steel fibre refractories.
This research has examined the influence of fibre geometry, fibre
alloy composition and fibre content of stainless steel melt extract
fibres on the performance of a proprietary 1400°C medium duty
calcium aluminate-bonded castable. It has also examined whether it
is necessary to obtain flexural and toughness measurements at
temperature in order to properly evaluate the performance of fibre
reinforcement or whether it is possible to obtain meaningful results
from a much simpler room temperature test. [Continues.]
