The present invention relates to an ultra-fast setting cement composition containing at least amorphous calcium aluminate including by weight, as compared to amorphous calcium aluminate total weight:

Ultra-fast setting cement based on amorphous calcium aluminate

Dense mortar based on binary ettringite binder, comprising at least one poly(alkylene oxide) comb polymer and at least one structuring organic resin

The invention relates to an ettringite binder for dense mortar, comprising calcium sulphates and a calcium aluminate mineral compound, the calcium aluminate mineral compound comprising calcium C and aluminum A oxides, soluble and combined in one or more crystallized and/or amorphous mineralogical phases, in such proportions that:

Ettringite binder for dense mortar, comprising calcium sulphates and a mineral compound of calcium aluminates

A clinker-type hydraulic binder obtained by burning comprising a magnesia spinel mineralogical phase and at least a calcium aluminate mineralogical phase, with a lime content less than 15% of the binder by dry weight. The magnesia spinel represents between 68% and 81% by dry weight of the binder and preferably the calcium aluminates consist essentially of CA and CA , with C&boxH;CaO and A&boxH;Al O . The invention also concerns the use of such a binder for making a refractory concrete and a method for making such a binder. The invention is useful for making steel ladles ( ), preferably for their wear lining.
