Comparisons Between Vibration and Self-Flowing Ultra-Low Cement Castables Properties in Al(2)O(3)-SiC-C System

In this study, the properties of self-flowing ultra-low cement castables in Al(2)O(3)-SiC-C system have been investigated and compared to vibration castables. The major physical and mechanical properties, microstmcture and corrosion behavior of these castables against slag have been evaluated. The results showed that the microstmcture of Al(2)O(3)-SiC-C self-flowing castable is more uniform than the vibrated structure. Also self-flowing castable has smaller pore Size and more uniform pore size distribution. Hence, density, strength, oxidation and slag resistance of the self-flowing castables is higher than that of vibration castables. Therefore, besides other benefits such as noise free, easy installation, fewer mold defects and reduced installation costs, Al(2)O(3)-SiC-C self flowing ultra low cement castables will have longer service life in comparison with vibration casables.
