EFFECT OF STEEL FIBERS ON REFRACTORY CASTABLES
Journal of Engineering, 2002 Reinforcement of refractory castables with steel fibers improves their strength for cracking and spalling and expands the service life. The results show that raising the temperature from 700°C to 900°C causes an increase in porosityand decrease in ...

Mullite macro-needles for reinforcement of refractory castables
Cerâmica, 2022 Ceramic macro-needles incorporation as reinforcement in commercial refractory castable was studied. Ceramic macro-needles (Ø2x20 mm) were made from kaolinite clay and gibbsite to obtain mullite as the main crystalline phase.

Paper 14: Developments in Refractory Castables
Proceedings of the Institution of Mechanical Engineers, Conference Proceedings, 1965 A short account, not intended for specialists, is presented of the constitution and general properties of refractory castable mixes. The basic factors affecting the performance of castable refractories are discussed and modern trends in the compounding of the mixes, and in the manufacture of the cement bond, are outlined. Attention is drawn to certain

Effect of Reactive Alumina on the Physico-Mechanical Properties of Refractory Castable
Transactions of the Indian Ceramic Society, 2013 The effect of reactive alumina and its different proportions on physico-mechanical properties of conventional high alumina castables were studied. The castables with different percentages of reactive alumina were prepared by using calcium aluminate ...
