Title:
セメント系システムに使用するための、低モルの均一に置換されたＨＥＣ
Document Type and Number:
Japanese Patent JP5922763
Kind Code:
B2
Abstract:
Hydroxyethylcellulose with a low molar substitution and which is uniformly substituted is useful in cement-based systems, including mortars. The cement-based system exhibits long pot life, as well as very high water retention capability at hot temperature, as well as better paste stability and optimized setting behavior for hot as well as cold temperature compared to typical, cement-based systems with commercial cellulose ether compounds. Less hydrophilic cellulose ethers such as methylhydroxyethylcellulose can be added as a second cellulose ether.
