Products for Retarders (RE)

  • Sika┬« Retarder N

    Sika Retarder N is used to retard the setting time of the concrete to allow concreting under conditions of high ambient temperatures and placing of mass concrete. It is designed to be used for pumped, prestressed and structural concrete.

     

    Use

    • Increases the setting time of concrete
    • Maintains workability
    • Used in high temperatures
    • Excellent for large concrete pours.

    Characteristics and Advantages

    • Prevents cracks in concrete where the formwork deforms.
    • Minimises the risk of cold joints.
    • After the initial retardation, the rate of hardening proceeds at a rate equivalent to, or greater than, unretarded normal concrete.
    • Delivery of concrete can be made over long distances from the premix concrete plant.
