PAREX 100 Newton Grout AW GB

Ultra-High Strength Anti-Washout Grout

PAREX 100 Newton Grout AW GB is an ultra-high strength grout specially formulated using a Portland cement powder mix. The mix design consists of a blend of fine and ultra-fine cements, high quality graded sands, and a set of synergistic admixtures. The mix design includes special shrinkage compensating components, which give a non-shrink grout in both the plastic and hardened states. Powerful plasticising agents produce a highly flowing grout at low water content. The product exhibits exceptional anti-washout properties and is ideal for underwater applications.

  • Pre-packaged, only requiring the addition of water.
  • Ultra-high strength.
  • Provides exceptional structural support and vibration resistance.
  • Shrinkage compensated.
  • Good strength gain after 24 hours, even at low temperatures.
  • Low water content.
  • Good freeze-thaw stability.
  • Resistant to sea water, petroleum products and mild alkali attack.
  • Can be used safely in contact with steel (due to very low chloride content).
  • Suitable for pumping applications.
  • Anti-washout properties, suitable for underwater applications.

1.0 kg of PAREX 100 Newton Grout AW GB will yield approximately 0.5 litres of mixed grout at the recommended water addition.

1000 kg (1 tonne) of PAREX 100 Newton Grout AW GB will yield approximately 0.52m³ of mixed grout at the recommended water addition.
25kg of PAREX 100 Newton Grout AW GB will yield approximately 12.5 litres of mixed grout at the recommended water addition.
Application steps

SUBSTRATE QUALITY

Concrete surfaces where grout is to be applied should be pre-saturated with clean water. The prepared concrete substrate must be thoroughly saturated with clean water for a recommended 1 hour before application of the grout. The surface must not be allowed to dry within this time. Prior to application of the grout, all water must be removed from within formwork, cavities or pockets and the final surface must achieve a dark matt appearance (i.e. saturated surface dry) without glistening.

SUBSTRATE PREPARATION

Concrete, Mortar, Stone:
Surfaces must be sound, thoroughly clean, free from ice, oils, grease, standing water and any loose or friable particles and any other surface contaminants.
Steel, Iron:
Clean, free from oil or grease, rust and scale, etc.
Shutter / Formwork:
Where formwork is to be used, all formwork should be of adequate strength, treated with release agent and sealed to prevent leakage. Sealing can be achieved by using Sikaflex®-11FC+ sealant beneath or around formwork and between joints. Ensure formwork includes outlets for extraction of the pre-soaking water.
A header box / hopper should be constructed on one side of the formwork so that a grout head of 150 - 200mm can be maintained during the grouting operation.

MIXING

Pour the required quantity of clean water (4.5 litres per 25 kg bag or 180 litres per 1000 kg) into the mixing vessel for each complete unit of PAREX 100 Newton Grout AW GB to be used. Slowly add the powder to the water whilst continually mixing. Mechanical mixing should be carried out using either a high torque slow speed drill with a Grout Stirrer or a grout mixer set on slow speed for small mixes; or for larger mixes forced action type mixers (high speed or colloidal mixing may cause thixotropy, leading to loss of flow). This material is not suitable for mixing by hand. It is of utmost importance that the product is mixed thoroughly enough that a grout consistency is obtained without the addition of further water. Fresh grout should be allowed to stand until the air entrapped by mixing has been released.

 

APPLICATION

Grout should be placed within 10 minutes of mixing or 60 minutes if kept mobile prior to placing. Continuous placing is important, pouring or pumping from one side of the form until the grout appears at the opposite side of the grouting area. Do not disturb once grouting has been completed. PAREX 100 Newton Grout AW GB may be placed at temperatures between 5°C and 35°C.

CURING TREATMENT

After the grout has initially hardened, remove formwork and trim edges while ‘green’.
Protect the fresh material from premature drying using an approved curing method (e.g. curing compound such as Sikafloor® ProSeal, moist geotextile membrane, hessian, polythene sheet, etc.). In cold weather, apply heat blankets to maintain a constant temperature.
Placed grout, which is exposed, should be cured in accordance with good concrete practice.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
