    MasterRheobuild 866 - High range water reducing superplasticising admixture

     

    How does MasterRheobuild 866 work?

    MasterRheobuild 866 is a ready to use, high range water-reducing agent designed to produce high slump concrete. This is a ready to use chloride free liquid admixture and meets ASTM C494 requirements for type F, and AS1478 requirements for High Range Water-Reducing Admixtures.

     

    What are the unique features of MasterRheobuild 866?

    MasterRheobuild 866 is compatible with both water reducers and air entraining agents approved under SAA, SANZ and ASTM specifications but it should be dispensed separately into the concrete mix. It should only be used with water reducers after specific testing at the proposed dose rates.

    What are the benefits of MasterRheobuild 866?

    • Very high workability
    • High water reduction
    • Superior cohesion
    • High early strength
    • Low shrinkage and creep
