Superplasticiser EB 821-R is a Retarding based on the Sodium Salt of high molecular weight Sulphonic Polymer.

• Enables the production of high strength concrete by reducing the water:Cement ratio.
• Excellent Slump Retention.
• Substantially improves workability at given water:Cement ratios, aiding flow and compaction around reinforcements.
• Enables self-compacting concrete to be made which eases placing indifficult situations and minimizes or eliminates the need for vibration.
• Aids compaction and the production of fair faced concrete.
• Enables very rapid pumping of concrete or lower pumping pressure required.
• Enables reduced cement contents to be used for given strength requirements.
