Calderys Range of Refractory Monolithics

High Alumina Binders (CALUNDUM & CAL-AL)

The CALUNDUM and CAL-AL series are high alumina calcium aluminate cements specifically developed for manufacturing refractory castables.

CALUNDUM

A medium-purity high alumina refractory binder that hydraulically sets and delivers strong, durable refractory castables when combined with refractory aggregates.

CALDE CAC 70 K (CAL-AL-70)

A high-purity refractory binder that offers superior strength, enhanced thermal stability, and reliable performance in demanding industrial environments.

Designed for applications requiring even higher purity and advanced refractory performance under extreme operating conditions.

Key Advantages:

  • High mechanical strength
  • Excellent thermal resistance
  • Reliable hydraulic setting
  • Improved refractory performance
  • Suitable for critical high-temperature applications

Dense Castables (WHYTHEAT)

The WHYTHEAT range consists of high-purity dense refractory castables designed for demanding high-temperature applications. These castables utilize CAL-AL-70 high-purity refractory cement as the binding agent, ensuring excellent thermal performance, durability, and low impurity levels.

Available in multiple grades, each WHYTHEAT formulation is engineered to suit specific operating conditions and service environments.

Key Features:

  • High-temperature resistance
  • Low impurity content
  • Excellent mechanical strength
  • Hydraulic setting properties
  • Suitable for casting, moulding, and gunning applications
  • Customizable for various furnace lining requirements

The WHYTHEAT series is recognized as one of the most efficient and reliable refractory castable solutions available in the market.

Low Cement Castables (ACCMON)

The ACCMON series comprises advanced low cement castables engineered for applications involving severe abrasion and extremely high operating temperatures.

These castables are formulated with:

  • Low lime content
  • Low porosity
  • High cold and hot strength
  • Superior resistance to abrasion and thermal stress

Due to their exceptional performance characteristics, ACCMON castables are widely preferred in critical operating zones where conventional refractory materials fail under aggressive service conditions.

Key Features:

  • High PCE (Pyrometric Cone Equivalent)
  • Excellent abrasion resistance
  • High strength across all temperature ranges
  • Enhanced durability
  • Improved thermal efficiency
  • Extended lining life

Insulating Castables (INSULYTE)

Calderys offers a range of insulating castables in the INSULYTE series to conserve heat in furnaces. They are light but adequately strong, and have low conductivity, thus serve as either hot face or back-up insulating refractory lining.
INSULYTE castables are produced in the density range of 400 to 1600 kg/m’. They are available mainly in two different grades – medium purity and high purity. In addition to standard products, tailor-made compositions are also supplied to suit customer requirements.

Medium Purity Dense Castables (FIRECRETE)

Medium purity dense castables are mainly the FIRECRETE brand refractory castables; these are suitable for use in medium temperature applications. This group of castables contains medium purity cement Calundum as the refractory binder. Depending on the type of refractory aggregates used in these castables, a series of FIRECRETE group of castable are manufactured. All these castables are used in oxidising atmospheres only.
These refractory castables are hydraulic setting and can be cast or moulded to any shape, and can also be suitably modified for gunning of furnace linings.

Refractory Mortars (ACCOSET)

MORTARS are joining materials for laying refractory bricks. Calderys produces a wide range of fireclay and high alumina mortars. These mortars are used as joining materials for various insulation and high alumina bricks. Mortars like Accoset 50, Mortar 70 are suitable for different types of insulation/fire bricks.
Some of the mortars are supplied as two component system, where liquid binder is separately provided with powder material.Where water is used as liquid component, the amount of water used should be such that it results in troweling consistency.

SHRINKKOMP 30/20

Free flowing nature helps to fill in gaps and gets self leveled

A Hydraulic Bonded non sinking grout

No gas forming agents for temporary expansion

Note: Performance warranty products under standard operating conditions
