Abstract
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.
Claims15
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 total weight of cellulose ether and microcrystalline cellulose.
(canceled)
An additive package for water-based inorganic binder compositions, the additive package comprising cellulose ether and microcrystalline cellulose wherein the microcrystalline cellulose is present at a concentration of 10-30 percent by weight based on total weight of cellulose ether and microcrystalline cellulose and the additive package is in a form of dry powder.
(canceled)
A method for increasing freeze-thaw stability, decreasing lumping upon hydrating and/or improved workability of water-based inorganic binder compositions, the process comprising blending a combination of cellulose ether and microcrystalline cellulose in the water-based binder composition wherein the microcrystalline cellulose is present at a concentration of 10-30 percent by weight based on total weight of cellulose ether and microcrystalline cellulose.
