<p>Thick self leveling mortar (I) comprises: 10-50 wt.% ettringite binder comprising calcium sulfates and calcium aluminate mineral compound containing calcium (C) oxide and aluminum (A) oxide, where the binder is soluble and combined into one or more amorphous and/or crystallized mineralogical phases, and the molar ratio of C/A is 1.2-2.7, preferably 1.6-2; and aggregates (50-90 wt.%) at least 30 wt.% of which is synthetic inorganic alumino-calcic aggregates comprising 30 wt.%, preferably at least 35 wt.% of alumina. Thick self leveling mortar (I) comprises: 10-50 wt.% ettringite binder comprising calcium sulfates and calcium aluminate mineral compound containing calcium (C) oxide and aluminum (A) oxide, where the binder is soluble and combined into one or more amorphous and/or crystallized mineralogical phases, the molar ratio of C/A is 1.2-2.7, preferably 1.6-2, and the sum of the weight of phases (C + A) is at least 30%, preferably at least 50% of the total weight of the calcium aluminate mineral compound; and aggregates (50-90 wt.%), at least 30 wt.% of which is synthetic inorganic alumino-calcic aggregates comprising 30 wt.%, preferably at least 35 wt.% of alumina, where the total wt.% of mortar is based on the total weight of dry mortar. Independent claims are included for: (1) wet mortar obtained by mixing the dry mortar with water in an amount such that the water/solids is less than 0.5 l; and (2) self-leveling surface coating obtained from the mortar.</p> |
