Abstract

La présente invention concerne un mélange à sec qui contient du ciment Portland, du ciment alumineux (ciment d'alumine) et du sulfate de calcium combinés à du sulfate de fer et/ou à du sulfate d'aluminium. Ce mélange convient particulièrement pour des matières à enduire, des matières de chape ou des matières de revêtement de sol sans joints. Ces matières à enduire, de chape ou de revêtement de sol sans joints sont caractérisées, après enduction et prise ou durcissement, par une surface particulièrement lisse présentant une rugosité nettement réduite par comparaison aux matières à enduire, de chape ou de revêtement de sol sans joints courantes. Il n'est ainsi plus nécessaire d'effectuer une rectification de dégrossissage de la surface enduite ou appliquée et il est nettement plus facile d'y coller un revêtement supérieur.
