A binder composition that includes cement, optionally calcium sulfate, at least one zinc salt and at least one alkylamine, and to a dry-mortar mixture that includes said binder composition. The present invention further relates to the use of a composition composed of a zinc salt and an alkylamine for achieving high early strengths in a binder composition.

The present invention provides a system for continuous production of sulfur polymer cement. The system may include a series of high shear mixers, such as twin screw mixers or compounding extruders, to which a sulfur-containing starting material is added at one end, followed by at least one stage at which a sulfur modifier is added. Micro-aggregate may be added at one or more stages. At the discharge end of the continuous system, an extrudate is produced, and a pelletizer may be used to form pellets of the polymerized sulfur and micro-aggregate material. The pelletizer may comprise a flowing cooled water system, e.g., underwater pelletizer. The formed pellets may then go through a dryer system and then to a dry storage collection system.

This application relates to making magnesium oxychloride boards. A magnesium oxychloride slurry is mixed by directing magnesium chloride, magnesium oxide, at least one phosphate, at least one inorganic salt, and water into a mixer and mixing these ingredients together to form a slurry. At least one filler is then mixed with the slurry. The slurry is directed to a mold. The mold is formed with the slurry to form a magnesium oxychloride board. The magnesium oxychloride board is then cured.
