ABSTRACT:
A reinforced refractory product having increased tensile strength is provided comprising a refractory material such as a phosphate bonded castable refractory having distributed therein ceramic fibers in yarn form consisting of roved bundles of filaments.
A method of distributing the ceramic fibers in the refractory is also provided wherein a mix of water and refractory material matrix is first formed and thereafter the fibers are added. Such method substantially reduced the risk of fiber damage during incorporation of the fiber in the matrix.
