CIMENT FONDU® is the most versatile of all Imerys Aluminates products.
CIMENT FONDU® is a calcium aluminate-based hydraulic binder, in contrast to Portland cements, which contain calcium silicates.


CIMENT FONDU® is used in a wide range of applications:

  • as a reagent in formulated products
  • as a hydraulic binder base for refractory and specialty concrete
  • as an accelerator for Portland cements.

When it is used on its own or as a hydraulic binder base for specialty concretes, CIMENT FONDU® can produces a number of specific properties:

  • quick setting 
  • excellent resistance to heat, thermal cycles and abrasion.

When CIMENT FONDU® is used in combination with specialty aggregates, such as ALAG® synthetic aggregates, superior performance can be achieved.

Unlike Portland cement, CIMENT FONDU® does not release lime during hydration. This property gives it good chemical resistance to acid corrosion and to a large number of aggressive substances.

The flow characteristics of CIMENT FONDU® are suited to all types of application processes, in particular casting and spraying.

Numerous applications in the civil engineering sector include:

  • industrial floors
  • replacement of road slabs
  • unloading and transfer bays
  • dam spillways, channels, etc.

In refractory applications, CIMENT FONDU® is primarily used in concrete insulation. When used in combination with suitable aggregates, it can be used at temperatures of up to 1,250° C.

In formulated products used in building chemistry, CIMENT FONDU® is used as a reagent or as the main binder for a vast array of products, including fast-setting mortar, tile adhesive, self-levelling products, etc.

CIMENT FONDU® is also used by tradesmen as an accelerator for Portland cement in rapid-sealing work and minor repairs. Mixtures of CIMENT FONDU® and Portland cement must not be used for structural purposes.

Beyond the minimum requirements established by standard EN 14647, the French production facility undertakes additional controls and abides by more stringent requirements as defined by the NF 002 standard, giving it compliance with the NF-Hydraulic Binder label.
