    Concrete set time adjusters 

    How does MasterSet adjust concrete set times?

    The MasterSet product series is a comprehensive range of admixtures that allows concrete producers to modify the setting time of concrete according to their specific project needs.

    What makes MasterSet a unique solution?

    Depending on the product selected, MasterSet admixtures enhance acceleration or retardation of cure. The hydration controlling products in the range are ideal for the stabilisation of long-haul concrete.

    What does the MasterSet range include?

    MasterSet products include:

    • ​Ready-to-use setting-time retarders that increase concrete setting time for a more uniform and predictable quality concrete that facilitates placing and finishing.
    • Setting time accelerators that decrease concrete setting time, improving early concrete strength and finishing characteristics.
    • Our innovative hydration controlling admixtures manage cement hydration, providing an economical alternative for dealing with slump loss and allowing returned plastic concrete or concrete wash water to be reused or recycled.​
