Comportamiento en Fractura De Hormigones Refractarios De Cordierita- Mullita y Liga Química

In this paper cordierite-mullite refractory concretes were prepared using the magnesia-phosphate chemical bond. Such concretes were constituted by cordieritic aggregates, a matrix of alumina, silica fumed and magnesium oxide, and different bonds (phosphoric acid, monoaluminum phosphate or monoammonium phosphate solutions). The setting occurred at room temperature in few minutes and then, cordierite-mullite was generated for heating at 1350 ºC. These
