Binder comprising calcium sulfoaluminate cement and a magnesium compound

摘要

The present invention relates to a binder comprising calcium sulfoaluminate (CSA) cement and a magnesium compound, to a method of enhancing strength development and/or increasing compressive strength of building structures from CSA binders and to the use of magnesium compounds as additives for increasing compressive strength of hydrated CSA binders wherein the magnesium compound is chosen from - low (300 to < 750 °C) to middle (750 to 1100 °C) burnt MgO, - magnesium hydroxide - magnesium salts of inorganic acids, preferably sulfate (e.g. MgSO
