Binding materials based upon magnesium compounds. Dry magnesium hydroxide and magnesium chloride are mixed in powder form, the weight ratio of the magnesium oxide contained in the magnesium hydroxide to magnesium chloride lying between about 0.8 and 2.0. Magnesium chloride may be used in the form of its hexahydrate, and, additionally, in the form of dihydrates. The dry product may be stored for months, in plastic sacks or bags, without coking. Thereafter, mixing the dry product with water yields magnesium oxide mortar. |
