Product Description

• Trial batch: The exact amount of water needed is determined by a trial batch to achieve the correct consistency, where a formed ball should hold its shape when tossed up.
• Pre-firing: Specifications are often tested after pre-firing to a specific temperature (e.g.,
  
  for 24 hours) to remove initial water.
• Standards: Test methods for properties like cold crushing strength and abrasion are often defined by national or international standards (e.g., IS 1528).

• Description and Key Properties

  Firecrete Super is primarily used in less critical zones of industrial equipment to provide a cost-effective, durable lining.

  • Maximum Service Temperature: Up to 1450C.

  • Chemical Composition: Contains approximately 70% Alumina ($Al_{2}O_{3}$) and a maximum of 5.5% Iron Oxide ($Fe_{2}O_{3}$).

  • Nature of Bond: Hydraulic, allowing it to set like standard cement after the addition of water.

  • Physical State: Supplied as a greyish-white dry powder, typically in 25kg or 50kg bags.

  • Performance: It offers excellent mechanical strength and resistance to thermal shocks, maintaining its structural integrity under intense heat.

  • Common Uses: Ideal for boiler linings (especially in the sugar industry), ovens, baking furnaces, and flue gas or hot air ducts.
