MasterRheobuild 561 (Formerly: Rheobuild 561) is a naphthalene sulphonate based high range water reducing/ superplasticizer admixture that improves the early and final strengths of concrete by giving Rheoplastic property.

MasterRheobuild 561 Fields of Application

• In the production of pumpable and nonpumpable high quality readymix concrete.
• When the transportation of concrete takes more than 1 hour.
• In the pouring of concrete where the concrete is pumped to a distance of more than 200 meters or to high places.

MasterRheobuild 561 Features and Benefits

• Decreases the amount of water at least 12% by weight compared to concrete without admixture.
• Enables lower water/cement ratio or high workability in the same water/cement ratio and easy pumpability compared to concrete without admixture
• Minimizes the negative effects of temperature on concrete workability.
