Liants hydrauliques à prise et durcissement rapides, leur préparation et leur utilisation pour la préparation de mortiers et bétons.

摘要

The invention relates to new hydraulic binders of the quick-setting and quick-hardening type. These binders contain from 50 to 99 % of a natural cement resulting from the calcination at a temperature comprised between 900 and 1 200 DEG C of a raw material containing sulphurated argillaceous phases and calcium carbonate in intimate mixing relationship, from 1 to 50 % of a pouzzolanic product or a filler, from 0 to 5 % of a mineral adduct and from 0 to 5 % of an organic adduct. The invention also relates to the method of preparation of said binders by dry mixing and simultaneous crushing of the various ingredients. The invention also relates to mixtures of said hydraulic binders with artificial cements.
