Abstract
Official abstract text for this publication.
A new water-based inorganic binder composition includes inorganic binder, cellulose ether and microcrystalline cellulose. A new additive for water-based inorganic binder compositions includes cellulose ether and microcrystalline cellulose. A method for improving the properties of water-based inorganic binder compositions includes blending a combination of cellulose ether and microcrystalline cellulose in the water-based binder composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A water-based inorganic binder composition comprising inorganic binder, cellulose ether and microcrystalline cellulose cellulose wherein the microcrystalline cellulose is present at a concentration of 10-30 percent by weight based on the total weight of cellulose ether and microcrystalline cellulose, and, further wherein the inorganic binder composition is in a form of a dry powder. 2. The composition of claim 1 , wherein the inorganic binder is selected from a group consisting of gypsum-based mortar and cement. 3. The composition of claim 1 , wherein the inorganic binder is gypsum-based mortar. 4. The composition of claim 1 , wherein the inorganic binder is cement. 5. The composition of claim 1 , wherein the combined concentration of cellulose ether and microcrystalline cellulose is in a range of 0.01 to 1.0 weight-percent based on total dry weight of the water-based inorganic binder composition. 6. The composition of claim 1 , wherein the microcrystalline cellulose is free of agglomerated additive materials.
