A hydraulic mineral composition has a matrix with a base of vitreous or crystallised silico-aluminates of calcium and magnesium, making up at least 25% and preferably at least 30% by wt of the composition, one or more oxide minerals and possibly one or more halogen minerals specifically chosen from oxides and halogens of Ti, V, Cr, Mn, Co, Ni, Cu, Pb, Ba, Sr, P, S, Na, K, Zr, Tl, As, Sn and Cd making up at least 5% of the composition, at most 31% of alumina (Al 2O 3), less than 10% of ferrite and less than 0.05%, preferably less than 0.01% of carbon with respect to the weight of the composition. Independent claims are also included for: (A) a cement product or hydraulic binder containing this composition; (B) the fabrication of this hydraulic mineral composition. |
