    Fosroc Structuro W415 constructive solutions

    A Superior high performance Low range concrete super


    plasticizer based on polycarboxylate technology

    Uses Technical support

    Structuro W415 is a low range super plasticizer intended for Fosroc provides a technical advisory service for on-site
    applications where high workability retention with increased assistance and advice on admixture selection, evaluation
    early and ultimate compressive strengths are required, and trials and dispensing equipment. Technical data and guid-
    it has been developed for use in: ance can be provided for admixtures and other products for
     Pumped concrete use with fresh and hardened concrete.

     Concrete requiring long workability retention


    Typical Properties
     High performance concrete
    Appearance : Pale yellow coloured liquid
    Advantages Specific gravity : 1.05 @ 25°C
     Increased early and ultimate compressive strengths Chloride content : Nil to BS 5075 / BS:EN934

     Increased flexural strength Dosage Guideline


     Improved adhesion to reinforcing and stressing steel The optimum dosage of Structuro W415 to meet specific
     Improved resistance to carbonation requirements should always be determined by trials using
    the materials and conditions that will be experienced in use.
     Lower permeability
    Dosage guideline range is between 0.2 to 2.0% by weight of
     Increased resistance to aggressive atmospheric cement or cementitious materials including PFA, GGBFS &
    conditions microsilica.
     Reduced shrinkage and creep Use at other dosages
     Increased durability Dosages outside the above dosage guidelines can be used
    to meet particular concrete mix requirements. Please
    Standards compliance
    contact Fosroc for advice in such cases.
    Structuro W415 conforms with BS 5075, BS:EN 934-2 and
    Effects of overdosing
    with ASTM C494 as Type F and G.
    Overdosage may cause delay in the setting time.
    Description

    Structuro W415 is differentiated from conventional super-


    plasticisers in that it is based on a unique carboxylic ether
    polymer with long lateral chains. This greatly improves
    cement dispersion. At the start of the mixing process an
    electrocstatic dispersion occurs but the presence of the
    lateral chains, linked to the polymer backbone, generate a
    steric hindrance which stabilises the cement particle’s
    capacity to separate and disperse. This mechanism consid-
    erably reduces the water demand in flowable concrete.

    Structuro W415 combines the properties of water reduction


    and workability retention. It allows the production of high
    performance concrete and/or concrete with high workability.

    Structuro W415 is a particularly strong hyperplasticiser


    allowing production of consistent concrete properties around

    The correct quantity of Structuro W415 should be measured Fire


    by means of a recommended dispenser. The admixture Structuro W415 is water based and non-flammable.
    should then be added to the concrete with the mixing water
    to obtain the best results. Contact Fosroc for advice regard- Cleaning and disposal
