Paper Title:
The Vibrative Casting with a Thixotropic Behavior
  Abstract

To prepare the vibrated casting slurries of waste tile particles, ultrafine colloids of the waste tile was added as a binder materials and as a thixotropic agent to avoid segregation between large and fine grains. The plasticity of the slurries was controlled by the rheology of colloids of the waste tile. To give thixotropic behavior, the dispersion and coagulation behavior of the colloidal suspension were investigated by the zeta potentiometer. The point of zero charge of the suspension was shown near pH 5 and maximum zeta potential was -55[mV] near pH 11. Maximum agglomerate particles were appeared near to the point of zero charge. The bending strength and water absorption of sintered bodies were more than 8.35kgf/cm2, and less than 5.0% above 1100 oC respectively. In addition, crystalline phase of sintered bodies were quarts and mullite. The micro-structure of the sintered body has a uniform pore size and distribution.
