    MasterGlenium ​SKY 1966

    Admixture for high-quality ready-mix concrete

    How does MasterGlenium SKY 1966 work?

    MasterGlenium SKY 1966 is a high-performance superplasticizer using a unique blend of state-of-the-art polymers specially engineered for ready-mix concrete. This high-range water-reducing admixture’s special formulation allows its delayed adsorption onto the cement particles and their efficient dispersal.

    Using MasterGlenium SKY 1966, you can obtain a high-quality concrete mix with extended workability without delayed setting characteristics, as well as superior concrete rheology.

    The unique polymer’s chemistry enables true workability retention across a broad spectrum of consistence classes (S4 to SF3). This is achieved without set retardation or reduced 24-hour strength performance.

    Under normal conditions, MasterGlenium SKY 1966 will stay within the target consistence class for 90 to 120 minutes.

    What is MasterGlenium SKY 1966 used for?

    MasterGlenium SKY 1966 is especially beneficial for producing high-quality ready-mix concrete, especially when both high water reduction and extended workability are needed – long-distance deliveries, deliveries with extended discharge times or in congested urban environments. 

    MasterGlenium SKY 1966 is designed to deliver workability retention for periods of up to two hours. MasterGlenium SKY 1966’s formulation has been optimised to meet the more challenging retention issues posed by the use of cementitious combinations such as, but not limited to, CIIIB.

    What are the benefits of MasterGlenium SKY 1966?

    MasterGlenium SKY 1966 offers the following benefits for:

    Ready-mix production

    • ​Concrete with low water-cement ratio meeting EN 206-1 without loss of workability.
    • Single product meeting many application needs
    • Enhanced retention performance with cements containing GGBS or PFA
    • Confidence of the same workability on site as when the concrete was produced

    Engineering design

    • ​Easier placing and faster strength development
    • Improved concrete surfaces
    • Guarantee of placing the same concrete as specified and ordered from the ready-mix plant
    • A more versatile concrete mix
    • Long pumping distances – horizontally and vertically

    On site

    • ​Insurance that concrete meets original specification
    • Confidence in concrete’s suitability for placement in areas of congested reinforcement
    • High-quality concrete with better durability​
