Fosroc Auramix 300

Product Details

Auramix 300 is a high performance retarding superplasticiser intended for applications where retardation and long workability retention are required, and it has been developed for use in:   Mass raft foundation,   Pumped concrete,   Concrete requiring long workability retention,   High performance concrete. Advantages   Increased retardation controls the heat of hydration and yields high ultimate strength   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 Standard Compliance Auramix 300 Complies with IS 9103-1999(2007) . It also complies with ASTM C 494 Type F & Type G depending on the dosage used. Description Auramix 300 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 300 combines the properties of water reduction and workability retention. It allows the production of high performance concrete and/or concrete with high workability. Auramix 300 is a strong superplasticiser allowing production of consistent concrete properties around the required dosage. Auramix 300 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 : 1.085 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 300 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 300 is available in 200 kg and 250 kg drums and bulk tanker
