CONSTRUCTION MATERIALS
CALCIUM ALUMINATE CEMENTS
Rapid setting, corrosion-, abrasion- and heat resistant calcium aluminates
Ciment Fondu has been renamed Ternal® Fondu.
Ternal® Fondu is a Calcium Aluminate specialty binder. Calcium Aluminates power key reference functions which are ideally suited to dry mix mortars for the construction industry: fast set, rapid hardening, early strengths, quick & self-drying, controlled dimensional stability, non-efflorescence.
Ternal Fondu is an accelerator of Portland cement in formulated products and is particularly recommended for mixes where speed and high performance are required.
Ternal Fondu does not release free lime during hydration. In concretes and mortars of low porosity, this key property yields a good resistance to acid attack and eliminates the major cause of efflorescence.
Ternal Fondu is commonly used either alone or in combination with other hydraulic binders, fillers and polymers in many high-range formulated building products. These include drymix mortars for floor preparation e.g. self-levelling compounds and screeds; tile adhesives and grouts; rapid repair or assembly of materials e.g. non-shrink grouts Ternal Fondu does not contain any additives nor crystalline silica.

Górkal 40 is a calcium aluminate -based hydraulic binder for refractory and building applications. It's advantages are rast strength development and short setting time. Górkal 40 material manufactured and controlled with respect to PN-EN 14647 norm.
Górkal 40 cement is irreplaceable in the installation of heating devices operating at temperatures up to 1300 °C, we recommend it for the construction of fireplaces, furnace lining, conducting repairs of chimney and ventilation ducts. The use of this cement significantly extends the life of these elements.
Górkal 40 is also perfect at low temperatures, it can be used even at -10 °C. It also works well in chemically aggressive environment (e.g. chlorides, sulphates). Characteristic properties of Górkal 40 cement, such as short bonding time and fast increase in mechanical strength make it possible to use it in urgent home repairs. It can therefore be used for screeds, window sills and lintels.
