Ciment Fondu® CALCIUM ALUMINATE CEMENT
Increase Safety ... Decrease Waste ... Save Time & Money Fondu Cement now available in easy to handle water tight plastic pails.
The 30 lbs pails can be easily carried by one person and dramatically reduces spillage and waste, as well as less loss to water damage than using 100lb paper bags. The following is from the Lafarge Calcium Aluminates, Inc. Product Data Sheet Applications § CIMENT FONDU® is a hydraulic binder with an alumina content of approximately 40%. § Composed mainly of the calcium aluminate phase, CIMENT FONDU® is ideally suited for refractory applications. § CIMENT FONDU® also contains secondary mineralogical phases containing combinations of CaO, Al2O3, iron oxide and SiO2. § The high proportion of mono calcium aluminate (CaO•Al2O3) in CIMENT FONDU® imparts excellent mechanical strength to refractory mortars and concretes. Despite the approximately 16% iron oxide content of CIMENT FONDU®, it is suitable for refractory applications where iron oxide can be tolerated. However, its use cannot be recommended for reducing atmospheres. The rheological properties of CIMENT FONDU® are well adapted to all types of placing methods, particularly for casting and gunning. § It is recommended for applications requiring rapid hardening properties, resistance to abrasion and mechanical shock, and exposure to intermediate temperatures. § This product contains no crystalline silica.

CIMENT FONDU® packaging (when in bags) is designed to protect it from humidity. However, it is recommended that CIMENT FONDU® not be placed in direct contact with the ground. When correctly stored, the shelf life of CIMENT FONDU® is at least 6 months. In most cases, its properties are retained for over a year.
