ALUMINITE is a refractory cement specifically designed for the production of heat-resistant, insulating mortars and concretes. ALUMINITE is made of calcium aluminates and aluminium rich minerals that are both ground to micron size..
By raising its surface temperature, its components are sintered which increases its melting point and mechanical strength. ALUMINIATE hardens quickly which contributes to its rapid demolding.
Recommended Usage
Heat-resistant, insulating mortars and concrete, including those resistant to thermal shock (with appropriate aggregates).
Fields of use include:
- The iron and steel industry
- The photochemical industry
- Incinerators
- The aluminium industry
- Ceramics
- Chimneys and braai areas
ALUMINITE is not suitable for non-refectory or non-insulating applications.
Precautions For Use
Given the high reactivity of this cement, care should be exercised during the curing process, particularly in hot, dry and windy climates.
Intensive curing is recommended three hours after application and over the next 24 hours.
The first temperature ramp rate should be gradual so as to avoid fissures caused by the rapid discharge of water.
A ramp rate of 50 C per hour from room temperature up to 600 C is recommended and should be maintained for two hours. Finally, the temperature can be raised to the required level.
Once the ALUMINITE is fired, subsequent temperature ramp rates are unaffected.
Dispatch and Storage
Available in 25kg bags, that must be stored in ventilated, dry conditions and protected from air and ground moisture.
