Abstract
A magnesium oxychloride cement (MOC) incorporating an emulsion of active cationic organo-silane and method of making same.
Claims21
A magnesium oxychloride cement (MOC) integrating an emulsion of active cationic organo-silane;
- light burnt magnesia;
- magnesium chloride hexahydrate;
- cementitious industrial by-products;
- and water, wherein the cementitious industrial by products is one or more materials selected from the group consisting of:
- fly ash, silica fume, ground granulated blast-furnace slag, wherein a weight ratio of light burnt magnesia and magnesium chloride hexahydrate is in the range 1.5 to 2.2, wherein the light burnt magnesia has a specific surface area of 120 m2/kg to 150 m2/kg, wherein the light burnt magnesia makes up 40% to 50% by mass of the MOC on a dry solids basis, wherein a mass (MSi) of the emulsion of active cationic organo-silane in the MOC complies with the following equation:
