CA 020 hitemp refractory cementCement Carborundum Mortar


Cement Carborundum mortar is used for laying and pointing fireclay or other alumina-based refractory brickwork. It can be used in contact with most refractories at elevated temperatures and has a very strong set at low temperatures, making it effective for lower temperature applications. Because of its fine, smooth texture, it is well-suited for dipped joints. The shelf life of this mortar, particularly in hot weather, is very good compared to many other mortars.
