What are calcium aluminates for?

• Refractory applications
• Building chemistry applications
• Technical concrete applications
• Merchants
• Mining
• Pipes and Wastewater
• Metallurgical flux

PRODUCT RANGE FOR REFRACTORY MATERIALS

Besides their heat-resistance properties and capacity to withstand thermal shock, which make calcium aluminates a key component in refractory applications, they also form an intrinsic part of recent developments:

• The trend to replace refractory bricks with calcium aluminate-based concrete is on the rise;
• Calcium aluminate-based refractory concrete provides a cost saving response to demand for a product combing a durable life and easy placing.

These different tendencies towards harmonization and globalization have given calcium aluminate-based concrete a significant potential for growth.

Kerneos offers a complete line of SECAR® cements and binders which provide specialised monolithic refractory concrete formulators with a tool for raising performance and reliability levels, while increasing the yield of their own products. The SECAR® product line integrates a range of fundamental properties:

• Better control over placing the concrete and post-application characteristics,
• A choice of application techniques,
• Excellent stability at very high temperatures (above 1800ºC),
• The achievement of high mechanical resistance,
• Excellent durability linked to good resistance to mechanical wear, thermal stress and corrosion.

Thanks to its R&D work and long years of practical experience, Kerneos has acquired a nuanced understanding of calcium aluminate behaviour in refractory concrete. This knowledge has played an important role in the ongoing development of the SECAR® product line.

THE SECAR® PRODUCT LINE: SOLUTIONS FOR REFRACTORY APPLICATIONS

The SECAR® product line covers all refractory concrete applications.

By relying on a wide range of refractory aggregates and additive combinations, SECAR® cements and binders can be used in all monolithic methods, from conventional methods to deflocculating techniques.

SECAR® cements and binders are perfectly adapted to designing refractory concrete, whether the concrete placing involves the classic method, vibration pouring, dry spraying or more innovative methods such as pouring without vibration, pumping or wet spraying. The range of possible refractory applications covers operating temperatures which can reach 1800ºC and above.

• CIMENT FONDU® is a cement with low alumina content
• SECAR® 51 is a cement with average alumina content
• SECAR® 71, SECAR® 712, SECAR® 80, SECAR Plenium® and SECAR Xeniom® are cements with high alumina content (link to a visual presentation of precision products expected in near future)
• ALAG® is an aluminous aggregate which is recommended for standard formula intended for use at temperatures which can reach 1100°C.
