Abstract
The present specification discloses ceramic matrix compositions, methods of making such ceramic matrix compositions and methods and uses for such ceramic matrix compositions.
Claims20
A ceramic matrix composition comprising:
- about 75% to about 99% of a hydraulic gypsum cement material, based on a total dry weight of the composition;
- about 0.1% to about 5% of a non-hydraulic gypsum cement material, based on the total dry weight of the composition;
- about 0.1% to about 10% of a crosslinked synthetic hydrogel, based on the total dry weight of the composition;
- and
- about 0.1% to about 10% of a binder, based on the total dry weight of the composition;
- wherein the ceramic matrix composition comprises a three-dimensional interconnected array of channels.
3 more elements
A method of making a ceramic matrix composition, the method comprising the steps of:
- depositing a slurry mixture into a form or a mold, the slurry mixture comprising about 28% to about 48% by volume of a hydraulic gypsum cement material, about 4% to about 15% by volume of a crosslinked synthetic hydrogel, about 0.01% to about 2% by weight/volume of a non-hydraulic gypsum cement material, about 0.1% to about 5% by weight/volume of a binder, and about 40% to about 62% by volume of water;
- and
- allowing the slurry mixture to set in order to form the ceramic matrix composition.
A method of treating a surface of a pre-existing material with a ceramic matrix composition, the method comprising the steps of:
- depositing a slurry mixture onto the surface of the pre-existing material, the slurry mixture comprising about 28% to about 48% by volume of a hydraulic gypsum cement material, about 4% to about 15% by volume of a crosslinked synthetic hydrogel, about 0.01% to about 2% by weight/volume of a non-hydraulic gypsum cement material, about 0.1% to about 5% by weight/volume of a binder, and about 40% to about 62% by volume of water;
- and
- allowing the slurry mixture to set in order to form the ceramic matrix composition.
