Abstract
Foamable magnesite cement, comprising a cement selected from magnesium oxychloride and magnesium oxysulphate cement, or a mixture thereof, together with one or more organic carboxylic acid(s) having a foaming coefficient lower than 1.80, and/or their anhydride(s) and/or their salt(s).
Claims41
A process for making a foamed magnesite cement, comprising the step of mixing:
- (a) water;
- (b) magnesium oxide;
- (c) a magnesium salt selected from the group consisting of magnesium chloride and magnesium sulfate;
- and
- (d) an organic compound selected from the group consisting of monocarboxylic acids having a foaming coefficient lower than about 1.8, anhydrides of said monocarboxylic acids, and salts of said monocarboxylic acids;
- thereby producing a foaming magnesite cement mixture.
