High alumina refractory cement/ acid-resisting refractory cement
Refractory cements correspond to a bond used in unshaped refractory material manufactured by the refractory industry.
According to the ISO 2008, refractory castable(refractory concrete) are prepared with a number of raw materials, which are bonded together with bonds, including hydraulic bond that sets and hardens when mixed with water. Also called refractory cements, those hydraulic bonds possess different grades. Calcium Aluminatesare part of refractory cements and are used in all castable families:
1.Regular Cement Castable or Conventional Castable 2. Medium Cement Castable 3.Low Cement Castable 4.Ultra Low Cement Castable
Refractory cements are mixed with refractory aggregates (bauxite, tabular alumina, White Fused Alumina, Brown Fused Alumina, andalusite, silimanite, chamotte, Alag, perlite, vermiculite, reclaimed material, bubble alumina…) and used with various installation techniques:
1.dry gunning 2.wet gunning or shotcrete 3. vibration casting 4.self-flow
