The aim of this study is to determine the properties of fired andalusite brick with silicon carbide addition. Brick samples were prepared by mixing, shaping, drying, and sintering at 1300 °C in a commercial tunnel kiln. The bulk density, apparent porosity, gas permeability, and cold crushing strength of fired brick samples were determined. Slag penetration test was investigated by static cup test with electric-arc furnace (EAF) dust recovery blend. The effects of SiC additions on the penetration properties of the samples have been investigated. The addition of SiC significantly affects the reduction behavior of metallic ingredients in EAF dust recovery on the brick surface. SiC shows the self-glazing properties in the brick and behaves as an antibarrier for zinc vapor.
