Refractory Mortar

Overview

Refractory Mortar is a high-quality heat-resistant bonding material used to joint, patch, and repair refractory bricks and monolithic linings in furnaces, kilns, boilers, and incinerators. It ensures strong adhesion, gas-tight joints, and high-temperature stability, providing a seamless bond between refractory components.

Formulated using high-purity refractory aggregates, binders, and special additives, our refractory mortar offers excellent thermal resistance, low shrinkage, and chemical stability — ensuring long-lasting performance under extreme service conditions.

Key Features

  • High Temperature Resistance – withstands up to 1800°C (depending on grade)

  • Excellent Bond Strength with fireclay and high alumina bricks

  • Low Shrinkage – prevents cracking during heating and cooling cycles

  • Good Plasticity & Workability – easy to apply with trowel or brush

  • Chemical & Thermal Shock Resistant

  • Air-Setting or Heat-Setting Grades Available

  • Ideal for both new installations and repairs

Types of Refractory Mortar

  1. Fireclay Mortar (30–45% Al₂O₃): For general-purpose brickwork in boilers, kilns, and furnaces.

  2. High Alumina Mortar (50–90% Al₂O₃): For high-temperature and abrasion-resistant applications.

  3. Silica Mortar: For coke ovens, glass furnaces, and acid-resistant environments.

  4. Magnesia-Based Mortar: For basic refractory applications in steel and non-ferrous industries.

Applications

  • Jointing and Laying of fireclay, high alumina, and basic bricks

  • Lining and Repair of furnaces, kilns, incinerators, and reactors

  • Boiler and Chimney Repairs

  • Refractory Patchwork and sealing of cracks

  • Industrial Applications:

    • Steel plants

    • Cement plants

    • Petrochemical units

    • Ceramic and glass industries

Advantages

  • Provides a strong, monolithic bond between bricks

  • Resistant to thermal cycling and chemical attack

  • Ensures gas-tight, durable joints

  • Easy to apply and maintain

  • Compatible with all grades of refractory bricks and castables

Packaging & Storage

  • Packed in 25 kg or 50 kg moisture-proof HDPE bags
