Product DescriptionHigh performance PCE based Super Plasticizingadmixture – Retarding type.
Uses

Auramix 350 is a high performance super plasticizer suitablefor low and high grade concrete and intended for applicationswhere high water reduction and long workability retentionsare required. 
Auramix 350 developed to use in:

 Long workability retention concrete.   Pumpable Concrete.  High performance concrete

Advantages
 Low viscosity admixture suitable for pumping different grades of concrete to greater heights.  Suitable for concrete having cement replacements and low water cement ratio.  Provides higher strength without increase in cement content or reduction in workability. Ideal for precast concrete production.  Reduce rate of workability loss normally associated with super plasticiser. Reduces shrinkage cracking because of lower water cement ratio. Makes the concrete water impermeable.  Better resistance to Carbonation.  Reduce Shrinkage and Creep.  Increase Durability.

Description

Auramix 350 is a unique combination of new generation SuperPlasticizing admixture – Retarding type based on polycarboxilicether polymer with long lateral chain. Electrostatic dispersionmechanism considerably reduces the water demand in flowableconcrete. It is supplied as a light brown liquid, instantlydispersible in water.

Auramix 350 disperses the cement particles effectively in theconcrete mix and hence exposes a larger surface area to thehydration process. This effect is used either to increase thestrength or to produce high workability concrete or reducecement content of concrete or to retard the setting time ofconcrete.

DosageThe optimum dosage of Auramix 350 to meet specific requirement should always be determined by conducting laboratory and batch trials. However the normal dosage ranges between 0.3 to 2.0 precent by weight of total cement or binder content.

Estimating
Packaging:Auramix 350 is available in 200kg, 250kg drums and bulktankers.

StorageAuramix 350 has a minimum shelf life of 12 months providedthe temperature is kept within range of 40C and 500C.

Product DescriptionAuracast 50 is a unique combination of the latest generation super plasticisers, based on polycarboxylic ether polymer with long side chains and short main chains. This greatly improves cement dispersion and as well as facilitate quick start of hydration process. At the start of the mixing process an electrostatic dispersion occurs but the cement particles capacity to separate and disperse. This mechanism considerably reduces the water demand in flowable concrete.

Auracast 50 is a strong super plasticiser allowing production of consistent concrete properties at required dosage.

Product DescriptionReebol Emulsion Xtra
Concentrated and emulsifi ed chemical mould release agent

Uses
For easy and stain free release of concrete moulds and formwork of all types. Particularly where wooden formwork is usedand de-moulding or stripping times exceed 24 hours.

Advantages

• Non-staining : No cleaning of unsightly oil stains if plastering is not required.
• High quality : Produces really fair faced fi nish concrete.
• Versatile : Can be used on all types of moulds.
• Minimises cleaning : Makes cleaning of form faces between pours very easy.
• Concentrate form : Reduces storage and transport costs.
• Water based : Only requires water for dilution.
• Aids corrosion inhibition

Description
Reebol Emulsion Xtra is supplied as a pale amber liquid whichturns emulsifi er when diluted with water to produce a chemicalrelease agent, combining the outstanding release properties ofsuch materials with the economy of a conventional oil. It reactswith the alkali in the concrete to form a thin water repellent skinon the surface of the mould which enables easy stripping fromthe hardened concrete.

Technical Support
Fosroc off ers a comprehensive range of high performance, high quality concrete repair and construction products. In addition, Fosroc off ers technical support service to specifi ers, end-users and contractors, as well as on-site technical assistance in locations all over the country.

Properties
Dilution rate - 1 part Reebol Emulsion Xtra: 6parts clear water (by volume) Formwork surfaces - May be used on wooden or metal surfaces. Particularly eff ective on resinous coated surfaces including Reebol Formcote coated wooden surfaces. Non-staining - Can be used safely with white cement. Specifi c Gravity - Typically 0.93 to 0.96 at 270C .

Application instructions

Mixing
First dilute Reebol Emulsion Xtra concentrate in the proportion of 1:6 with water, using a clean container and stirring thoroughly until evenly mixed. If the solution is not used the same day, it should be stirred again before use and may require very good stirring after 5 days. New Moulds : No preparation is normally necessary Metal moulds showing signs of rust, must be wire brushed or treated with emery cloth and burnished clean before coating. New timber : Plywood will give superior results and much extended re-use if fi rst coated with Reebol Formcote. Used moulds : Must be thoroughly clean and free from old concrete, dirt, cement laitence, old mould oil and other contaminations. Use a strong detergent for removal of oil and grease; Reebaklens for cement and concrete deposits. Application : Apply the Reebol Emulsion Xtra 1:6 water dilution to the face of the formwork by spray, brush or cloth. Only one coat should be applied ( as thinly as possible except on very absorbent new timber where two coats may be necessary for the fi rst application only ) and allow to dry. If the formwork is not used for several days, a further coat may be applied. Only a very thin fi lm of Reebol Emulsion Xtra should be applied. Excess could lead to surface dusting of the concrete. The best results are obtained by applying with a fi ne mist sprayer. Where a cloth is used, it should fi rst be soaked in the release agent and then squeezed out well before applying. This ensures the thinnest possible fi lm. Reebol Emulsion Extra is not generally recommended where demoulding is required within 24 hours, although excellent results may be obtained with shorter times. Drying time : It is essential that the Reebol Emulsion Xtra is thoroughly dry before placing concrete. Otherwise, being an emulsion, its performance may be impaired. In condition of high humidity drying times will be much longer than in warm dry conditions.
