What Factors Affect the Performance of Cement-Free High-Alumina Self-Flowing Castables?

The effect of the particle size distribution (two different particle sizes) on the self-flowing (without vibration) and other physical and chemical properties of high-alumina (Al2Os> 90%) cementless castables. For the castable with the best sol (binding agent) content, its various properties, including bulk density, apparent porosity, normal temperature compressive strength, load softening point, permanent linear change, peeling resistance, and high-temperature flexural strength, also have a certain impact.
