Abstract
A hydraulic binder includes at least 70% by weight of a solid mineral compound consisting of at least one mixture of silica, alumina and alkaline-earth metal oxides, the total sum of CaO and MgO representing at least 10% by weight of the solid mineral compound, and an activation system of which at least 30% by weight is a phosphoric acid-derived salt. Construction products can obtained from a mortar composition including such a binder.
