    Sika® Pozzolith® (formerly known as MasterPozzolith®) 311RD - Retarding type water reducing admixture for improving concrete

    How does MasterPozzolith 311RD work?

    MasterPozzolith 311RD is a ready-to-use liquid admixture for making better, more uniform concrete. It reduces the quantity of mixing water required to produce concrete of a given consistency while retarding the setting time to facilitate placing and finishing.

    Recommended uses:

    MasterPozzolith 311RD admixture is recommended for use in all types of concrete where moderate to extended retardation of set and improved performance are required or desired such as:

    • Large pours to avoid cold joint and reduce thermal cracking
    • Long hauls of readymixed concrete
    • Hot weather concreting
    • Slipform concrete for controlled and predictable setting time
    • Precast and prestressed concretes

    What are the features and benefits of MasterPozzolith 311RD?

    MasterPozzolith 311RD admixture aids in the production of concrete with these special properties:

    • Mild to extended retardation - depending on dosage.
    • Reduced water content for a given consistency.
    • Improved cohesiveness and workability.
    • Better finishing characteristics
    • Plus all the basic benefits of a normal plasticiser.
    • Increased strength - compressive, flexural and bond of concrete and air content.
    • Reduced cracking and permeability - improved watertightness.
    • Greater resistance to salt water and sulphates.
    • Increased durability.
