ABSTRACT:
An unwrought refractory composition, in particular for producing glass furnace hearths, includes a base mixture comprising in wt. %: 1 to 6% of a hydraulic cement, and 94 to 99% of particles of at least a refractory material mainly consisting of alumina (Al2O3), zirconia (ZrO2) and silica (SiO2), the fraction of the particles of the base mixture having a size less than 40 μm being distributed in wt. % relative to the weight of the base mixture, as follows: fraction<0.5 μm: ≧4%; fraction<2 μm: ≧5%; fraction<10 μm: ≧16%; fraction<40 μm: 29–45%, the refractory composition further comprising, in wt. % relative to the weight of the base mixture: 0.02 to 0.08% of organic fibers, and 0.075 to 1% of a surfactant.
