Generally, shale brick is used for applications where thermal shock is not a factor and minimum absorption is required. Shale brick contains sufficient integral iron to provide high strength and resistance to abrasion.
BELDEN Brick Company has been our main supplier of red shale acid resistant Type II Doubles, Singles and Vertical Fibre Floor Pavers. These are used widely in acid plants.
“Belden chemical resistant brick, backed by more than 135 years of brick making experience, are manufactured of specialty selected American shales and fire clays. These are fine-ground and specifically formulated for density and strength and fired at over 2000°F. This process results in brick that resists virtually all corrosive liquids and gases, except for acid fluorides and strong hot caustics” (htt)
