Porogenic Behavior of Water in High Alumina Castable
Direct casting is a processing method that can produce large parts of complex geometry It uses dispersions of ceramic particles in water and a hydraulic binder for consolidation Studies on castable structures have reported the generation of a significant fraction of pores due to the presence of water This effect occurs because drying preserves part of the interparticle pores originally
