Product description

Aluminite is a refractory cement especially designed to produce refractory and isolating mortars and concretes. Aluminite is made of calcium aluminates and alumina-rich minerals, both milled to the size of microns. By increasing the service temperature, its components are sintered and ceramised, which increases its melting temperature and its mechanical strength. Besides, it hardens quickly, which contributes to its fast release and/or implementation.
