    ​MasterGlenium SKY 925 

    High range water reducing admixture for concrete 

    ​MasterGlenium SKY 925 is a superplasticizer based on a unique blend of state of the art polymers. MasterGlenium SKY 925 is specially engineered for ready-mix concrete. Its particular configuration allows its delayed adsorption onto the cement particles and disperses them efficiently. 

    Fields of Application  

    MasterGlenium SKY 925 is especially beneficial for the production of high quality ready-mix concrete particularly when high water reductions are required in combination with a requirement for an extended period of workability, e.g. long-distance deliveries, deliveries with extended discharge times or in congested urban environments. MasterGlenium SKY 925 is designed to exhibit workability retention for periods up to 2 hours. The formulation of MasterGlenium SKY 925 has been particularly optimised for the more challenging retention issues that can be posed by the use of cementitious combinations such as, but not limited to, CIIIB. 

    MasterGlenium SKY 925 also has the ability to enable the use of aggregates such as recycled materials and crush rock fines that could be of variable quality.

    Characteristics and Benefits

    MasterGlenium SKY 925 offers the following benefits for the ready-mix concrete industry: 

    The ready-mix producer:
    • Production of a concrete with low water cement ratio that meets EN 206-1 without loss of workability.
    • Single product for many application needs.
    • Enhanced retention performance with cements containing secondary cementitious materials eg. GGBS, PFA, limestone powder.
    • Confidence that the workability will be the same at the job site as it was when first produced.

    The contractor / applicator:
    • ​Easier placing and faster strength development.
    • Improved concrete surfaces.
    • Enhanced rheology.
    • Guarantee to place the same concrete as specified and ordered from ready-mix plant.
    • More versatile concrete mix.
    • Long pumping distances both horizontally & vertically
    • Easy placement and compaction

    The engineer:
    • ​Insurance that concrete meets original specification
    • Confidence in the concrete’s ability to be paced in areas of congested reinforcement.
    • High quality concrete with better durability.​
