Low Cement Castable Definition

  • Castable cement has over 10~30% cement content.
  • Low cement castable is just content 3~8% cement.
  • Ultra low cement castables just have 1% cement content.
  • Non-cement is castable refractory without cement content.

Low Cement Castable Composition

Low cement castables for sale is calcium aluminate cement binding refractory castable and have less than 2.5% CaO content. Base materials adopt ultrafine powder that have the same or similar chemical component with main material and have cohesive bonding function instead of part or most calcium aluminate cement. This kind of castable belongs to concomitant hydration and cohesive bonding castable.

Low Cement Castable high alumina, is developed based on refractory castable bonding clay, which has the varieties of low cement castables, ultra low cement castables, non-cement or submicron powder and soild binder.

  • High density.
  • Low porosity.
  • High strength.
  • Low abrasion.
  • Thermal shock resistance.
  • Resistance to erosion.
  • Good using effect.

Low Cement Castable Properties
