Superplasticizer Fosroc Auramix 400, Packaging Size: 250 kg

Product Details

Auramix 400 is a high performance superplasticiser intended for applications where high water reduction and long workability retention are required, and it has been developed for use in:   Self-compacting concrete,   Pumped concrete,   Concrete requiring long workability retention,   High performance concrete. Standard Compliance Auramix 400 complies with IS:9103-1999(2007). It also complies with ASTM C494 Type G depending on the dosage used. Advantages   Low viscosity suitable for pumping of different grades of concrete to higher fl oors   Higher E modulus   Improved adhesion to reinforcing and prestressing steel   Better resistance to carbonation   Lower permeability   Better resistance to aggressive atmospheric conditions   Reduced shrinkage and creep   Increased durability Description Auramix 400 is a unique combination of the latest generation superplasticisers, based on a polycarboxylic ether polymer with long lateral chains. This greatly improves cement dispersion. At the start of the mixing process an electrostatic dispersion occurs but the cement particle's capacity to separate and disperse. This mechanism considerably reduces the water demand in fl owable concrete. Auramix 400 combines the properties of water reduction and workability retention. It allows the production of high performance concrete and/or concrete with high workability. Auramix 400 Technical support Fosroc provides a technical advisory service for on-site assistance and advice on mix design, admixture selection, evaluation trials and dispensing equipment. Properties Appearance : Light yellow coloured liquid pH : Minimum 6.0 * Volumetric mass @ 200 C : 1.09 kg/litre Chloride content : Nil to IS:456 * Alkali content : Typically less than 1.5 g Na2O equivalent / litre of admixture. * The uniformity parameters like specifi c gravity, pH, chloride content etc. will vary for specifi c customer requirements and mix design. Please refer our MTC issued for specifi c product confi guration for measuring our product parameters that will be constantly and consistently administered. Dosage The optimum dosage of Auramix 400 to meet specifi c requirements should always be determined by trials using the materials and conditions that will be experienced in use. The normal dosage range is between 0.5 to 3.0 ltrs/100 kg of cementitious material. Use at other dosages Dosage outside the normal range quoted above can be used to meet particular mix requirements. Contact Fosroc for advice in these cases Effects of overdosing Overdosage may cause delay in the setting time and segregation. Estimating Packaging Auramix 400 is available in 200kg and 250kg drums and bulk tanker.
