CA 2671185
A cementitious composition including cement, water, and a rheology modifying additive (RMA) is provided. The inclusion of the RMA improves the cementitiuous composition's response to vibration, and dampens out differences due to minor fluctuations in initial slump of the composition. The RMA may include a dispersant for cementitiuous compositions. The cementitious composition may optionally include other admixtures or additives known in the industry. A method for making the cementitious composition is also provided.
La présente invention concerne une composition de ciment comprenant du ciment, de l'eau et un additif modifiant la rhéologie (AMR). L'inclusion de l'AMR améliore la réponse à une vibration de la composition de ciment, et attenue les différences dues aux fluctuations mineures dans le coulage initial de la composition. L'AMR peut comprendre un agent de dispersion pour des compositions de ciment. La composition de ciment peut éventuellement comprendre d'autres mélanges ou additifs connus dans l'industrie. La présente invention concerne également un procédé de préparation de la composition de ciment.
