Abstract (en)
[origin: WO2015007661A1] Composition comprising at least one calcium-magnesium compound corresponding to the formula aCaCO3.bMgCO3.xCaO.yMgO.zCa(OH)2.tMg(OH)2.uI, in which I represents impurities, a, b, z, t and u being mass fractions each ≥ 0 and ≤ 50%, x and y being mass fractions each ≥ 0 and ≤ 100%, with x + y ≥ 50% by weight, relative to the total weight of said at least one calcium-magnesium compound, which is in the form of particles, said composition having a combined content of calcium and magnesium in the form of oxides of greater than or equal to 20% by weight and being in the form of compacts, each compact being formed from said compacted and shaped particles of calcium-magnesium compounds, said compacts having a Shatter test index of less than 10% enabling very good dropping resistance and good ageing resistance, the process for the manufacture thereof and the use thereof.
