    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.

    摘要: A method of forming a lightweight concrete comprising lightweight aggregates (LWA) made from recycled materials and the resulting composition. The lightweight concrete may be formed by adding calcium sulfoaluminate (CSA) cement and a specialized grout to an amount of water in a mixer, wherein a ratio of the water to the CSA cement is 1 quart to every 10 lbs of CSA cement. The CSA cement, specialized grout, and water may be blended to a smooth consistency. LWA may be added to the blended CSA cement, specialized grout, and water, wherein a ratio of the CSA cement to LWA is 60/40 by weight. The mixture of LWA, CSA cement, specialized grout, and water may be poured over a fiberglass rebar. The mixture may be allowed to cure and before being densified with a lithium densifier.

    摘要: Concrete compositions, concrete articles and methods of producing the articles are disclosed in which a portion of the cement is replaced by sulfur, preferably plasticized sulfur. Cost saving is thereby achieved and the articles exhibit improved scaling resistance on exposure to acid and on freeze-thaw cycling in a sodium chloride-containing environment.
