The exacting requirements on the durability of electrolysis cells used to make produce aluminum - the service life of which is determined mainly by the durability of the bottom - are driving improvements in the quality of carbon-bearing lining materials which are used. A readily compactible cold-rammed bottom refractory in bulk form is needed to solve the problems encountered in forming the vulnerable joints between the lining blocks and at the periphery of the bottom. The introduction of a plasticizing additive to coal-tar pitch effectively lowers its softening point and viscosity, which improves the plastic properties of the bulk carbon refractory. © 2013 Springer Science+Business Media New York.
