Process for the production of refractory cements, characterized in that in a first stage, alumina is reacted with syrupy phosphoric acid, to give a fluid binder of aluminum phosphate and, in a second, said fluid binder of aluminum phosphate is reacted with at least one refractory, solid, cold-setting component, reactive with aluminum phosphate and / or capable of absorbing the water released in the setting of the cement or the water required to prepare a workable mixture; in the presence of at least one heat conductive refractory charge. |
