Abstract: The present disclosure concerns an aluminosilicate having a Blaine fineness of about 500 m2/kg to about 3000 m2/kg and/or a specific surface area of about 4 m2/g to about 20 m2/g, as well as the uses thereof. The present disclosure also comprises a dry cementing composition and a mortar or concrete composition, the compositions comprising said aluminosilicate. The present disclosure also comprises a process for the manufacture of aluminosilicate. The process comprises: roasting a spodumene concentrate in an acid medium; leaching the acidic roast spodumene concentrate so as to obtain a mixture comprising a solid comprising the aluminosilicate and a leachate; and separating the aluminosilicate from the leachate in an acid medium, wherein said aluminosilicate contains a calcium concentration of less than about 5%.
