  • Introduction:

    The model RO - NX is a sort of non - air - entraining super plasticizer synthesized chemically. Its chemical name is naphthalene sulphonate formaldehyde condensate and it has a strong dispersing effect on cement particles. For preparation of high flowing concrete, cast- in - situ with early - strength or high - strength requirements and precast units, RO - NX has a good effect to comprehensively enhance and improve various performances of concrete and be used widely in roads, bridges, dams, ports, tunnels, electricity, water conservancy and civil engineering, steamed curing and nature conservation to the precast units etc. Currently on the market, the RO - NX is divided into high concentration and low concentration based on sulfate content. This product complies with the national standard GB 8076 - 2008 of super plasticizer indicators.

     

  • Specification:

    Powder: RO - NX (type I)

  • Applications:
    (1) It can reduce cement amount by 10 - 25% when the concrete strength and concrete slump are almost the same.
    (2) It is especially applicable to flowing concrete, plasticized concrete, steam - cured concrete, impervious concrete, waterproof concrete, natural curing precast concrete, reinforced concrete and prestressed reinforced concrete, and high - strength and ultra - high -strength concrete.
