A process for the preparation of a sulphur cement product is disclosed. Sulphur is mixed with a coupling agent and with a particulate inorganic material at a temperature at which sulphur is molten to obtain a molten sulphur cement product, which is solidified. The coupling agent is supplied as a solid composition comprising the coupling agent and at least 10wt%, based upon the weight of the solid composition, of carrier material selected from one or more of wax, inorganic filler and polymer. The coupling agent is chosen from the group of organosilanes and organotitanates.

La présente invention concerne un procédé pour la préparation d'un produit de ciment au soufre. Du soufre est mélangé avec un agent de couplage et avec un matériau inorganique particulaire à une température à laquelle le soufre est fondu pour obtenir un produit de ciment au soufre fondu, qui est solidifié. L'agent de couplage est fourni sous la forme d'une composition solide comprenant l'agent de couplage et au moins 10 % en poids, sur la base du poids de la composition solide, de matériau véhicule choisi parmi une cire, une charge inorganique et/ou un polymère. L'agent de couplage est choisi dans le groupe des organosilanes et des organotitanates.
