HIGH BELITE-CONTAINING SULFOALUMINOUS CLINKER, METHOD FOR THE PRODUCTION AND THE USE THEREOF FOR PREPARING HYDRAULIC BINDERS.

摘要

The invention relates to a belite-sulphoaluminous clinker, to its method of manufacture and its use for the preparation of hydraulic binders, and comprising as a mineralogical composition: 5 to 25%, preferentially 10 to 20% of calcium aluminoferrite phase of a composition corresponding to the general formula C2AXF (1-X), with X ranging from 0.2 to 0.8. - 15 to 35%, preferentially 20 to 30%, calcium sulphoaluminate phase 'yee' limit (C4A3 $), - 40 to 75%, preferably 45 to 65% belite (C2S), - from 0.01 to 10% of one or more minor phases selected from calcium sulphates, alkaline sulfates, perovskite, calcium aluminates, gehlenite, free lime and periclase, and / or a glassy phase, and at least one secondary element selected from sulfur, magnesium, sodium, potassium, boron, phosphorus, zinc, manganese, titanium, fluorine, chlorine, the total content of said secondary elements being lower or equal to 15%.
