    SikaRapid® AC 534 (formerly known as MasterSet® AC 534) - Accelerating admixture

    How does MasterSet AC 534 work?

    MasterSet AC 534 patented, ready-to-use, liquid admixture is formulated to accelerate time of setting and to increase early concrete strengths. It does not contain calcium chloride and is formulated to comply with ASTM C 494/C 494M type C, accelerating, admixture requirements.

    What are the fields of application?

    • Reinforced, precast, pumped, flowable, lightweight or normal weight concrete and shotcrete (wetmix)
    • Concrete placed on galvanized steel floor and roof systems which are left in place
    • Prestressed concrete
    • Fast-track concrete construction
    • Concrete subject to chloride ion constraints
    • 4x4TM Concrete
    • Self-consoildating concrete (SCC)
    • Previous concrete

    What are the features and benefits of MasterSet AC 534?

    • Accelerated setting time across a wide range of temperatures
    • Increased early compressive and flexural strengths
    • Earlier finishing of slabs - reduced labour costs.
    • Reduced in-place concrete costs
    • Reduces or eliminated heating and protection time in cold weather
    • Earlier stripping and reuse of forms
    • Superior finishing characteristics for flatwork and cast surfaces
