| 摘要 | The present invention provides a process for the preparation of sulphur cement or a sulphur cement-aggregate composite comprising the following steps: (a) admixing at least an inorganic filler and/or aggregate and a polysulphide-containing organosilane having at least two organosilyl groups and allowing the organosilane to react with the inorganic filler and/or aggregate; (b) admixing during or after step (a) elemental sulphur with the inorganic filler and/or aggregate at a temperature at which sulphur is liquid to obtain an admixture comprising molten sulphur and inorganic filler and/or aggregate; and (c) solidifying the admixture to obtain sulphur cement or a sulphur cement-aggregate composite. The invention further provides sulphur cement or a sulphur cement-aggregate composite obtainable by such process and the use of a polysulphide-containing organosilane having at least two organosilyl groups as coupling agent in sulphur cement or a sulphur cement-aggregate composite. | ||||||
