    ​MasterSet R107

    Low dosage, retarding and plasticising admixture for concrete​


    MasterSet R 107 is a liquid admixture, which acts on cement particles in the mix, combining the effects of a powerful plasticiser and deflocculating agent with controlled retardation.


    • Hot weather concreting, where controlled delay to initial set is of prime importance.
    • Ready-mix concrete, where workability retention coupled with retardation of initial set are beneficial. 
    • To improve cohesion, workability and compaction in concretes using poorly graded/shaped fine aggregates.
    • Large slabs or bridge decks, etc., where extension of vibration limits is beneficial to avoid cold joints.


    • Considerably extends vibration limit of concrete mixes, thus reducing incidence of honeycombing and cold joints.
    • Reduces placing problems in hot weather concreting, by improving workability and workability retention.
    • Improves trowelability and surface finish.
    • Improves pumpability of concrete.
    • Considerably reduces permeability.
    • Enables economies in mix designs to be achieved.​
