High Alumina Refractory Mortar – Reliable Performance for High-Temperature Operations

Written by

High-temperature refractory bricks are laid and repaired using High Alumina Refractory Mortar, a specifically made bonding material. It is essential in industries that require strong bonding, durability, and heat resistance. Premium-grade high-alumina refractory mortars from BM Enterprises, a leading refractory producer and supplier, ensure enduring furnace and kiln performance.

Understanding High Alumina Refractory Mortar

High-grade alumina, fire clay, and bonding agents comprise this mortar, enhancing its resistance to high temperatures. High alumina cement mortar is perfect for industrial furnaces, kilns, and boilers because it has superior resistance to slag, alkali, and thermal shock compared to regular fire clay mortar.

Key Features of High Alumina Refractory Mortar

  • High Bonding Strength: Provides a solid joint between refractory bricks.
  • Excellent Thermal Resistance: Can withstand temperatures up to 1700°C.
  • Easy Application: Ready-to-use mixture requiring minimal preparation.
  • Durability: Performs effectively under harsh industrial conditions.

Types of High Alumina Mortar Available

BM Enterprises manufactures a complete range of mortars tailored for various temperature needs:

Mortar 50

Suitable for moderate-temperature applications like boilers and small furnaces.

Mortar 70

Best for medium to high-temperature furnaces, offering superior bonding and thermal stability.

Mortar 80

High-alumina grade designed for heavy-duty furnaces and industrial kilns.

Mortar 90K

A premium-grade mortar with exceptional alumina content, capable of handling extreme heat conditions and corrosive environments.

Applications of High Alumina Refractory Mortar

These mortars are widely used in:

  • Steel and Iron Industries for blast furnaces and ladles
  • Cement Plants in rotary kilns and preheaters
  • Power Plants in boilers and incinerators
  • Glass and Ceramic Factories for melting units
  • Petrochemical Units for reactors and reformers

Difference Between Fire Clay Mortar and High Alumina Mortar

High alumina mortar has superior strength, corrosion resistance, and temperature endurance, making it perfect for high-heat applications, whereas fire clay mortar has a lower alumina concentration and is appropriate for regions with moderate heat.

High Alumina Cement Mortar vs Fire Clay Cement

For increased heat and corrosion resistance, high alumina cement mortar is made with a higher alumina ratio (50–90%). Conversely, fire clay cement is less expensive but better suited for milder applications with temperatures below 1350°C.
