Low Cement Castables
Reframon LC is a low cement Castable having high strength at all temperature levels. These Castables are used in locations needing high abrasion resistance.
Ultra Low Cement Castables
Reframon ULCC are ultra-low cement castables which contain even lower level of cement than low cement castables.
Above LC/ULCC Castables offers following advantages:
Low CaO content ensures high refractoriness.
Excellent hot strength and MOR at all temperatures.
Lower apparent porosity after firing offers better corrosion resistance.
High abrasion and spalling resistance.
High volume stability.
