COMPOSICION DE CEMENTO ACUOSA

Una composición acuosa fresca de cemento que contiene un cemento hidráulico y un éter de celulosa caracterizada porque la composición contiene un éter de metil etil celulosa que tiene un GS de metilo de 0, 4-2, 2, un GS de etilo de 0, 05-0, 8, y una SM de hidroxialquilo-(C2-C3) de 0-2. A fresh aqueo...

Summary:Una composición acuosa fresca de cemento que contiene un cemento hidráulico y un éter de celulosa caracterizada porque la composición contiene un éter de metil etil celulosa que tiene un GS de metilo de 0, 4-2, 2, un GS de etilo de 0, 05-0, 8, y una SM de hidroxialquilo-(C2-C3) de 0-2. A fresh aqueous cement composition suitable for building purposes is described. It contains, besides a hydraulic cement, a methyl ethyl cellulose ether having a DS methyl of 0.4-2.2, a DS ethyl of 0.05-0.8 and a MS hydroxy-(C2-C3)-alkyl of 0-2. The celulose ether imparts excellent rheology properties, including a high water-retention combined with a long open time, to the cement composition. A dry blend and a rheology additive containing the cellulose ether are also described.
