Parex 100 Newton Grout
Ultra-High Strength Cementitious Grout
Parex 100 Newton Grout is a one-part, ultra-high strength cementitious grout. 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.

Application
Mixing Ratio
Water : mortar powder = 1 : 5.55 parts by weight (4.5 litres of water per 25kg bag, or 180 litres per one tonne bag).
Layer Thickness
10 mm minimum / 100 mm maximum
Product Temperature
+5oC minimum / +35oC maximum
Ambient Air Temperature
+5oC minimum / +35oC maximum
Substrate Temperature
+5oC minimum / +35oC maximum
Pot Life
Up to 60 minutes if kept mobile after mixing.
Setting time
~80 minutes at +20oC
Initial set time
~60 minutes at +20oC
Consumption
Depends on the substrate roughness and thickness of layer applied. As a guide, one 25kg bag yields approximately 12.5 litres of mortar.
Yield
1.0kg of Parex 100 Newton Grout will yield approximately 0.5 litres of mixed grout at the recommended water addition.
1 tonne of Parex 100 Newton Grout will yield approximately 0.52 m³ of mixed grout at the recommended water addition.
The yield per 25kg of Parex 100 Newton Grout is approximately 12.5 litres.
NOTES ON INSTALLATION
- Do not exceed stated water addition.
- Not to be used for concrete repair works.
- Do not use vibrating pokers.
- Use only on clean, sound substrate.
- Avoid application in direct sun and / or strong wind.
- Pour or pump from one side only.
- Keep exposed surfaces to a minimum.
- Do not add additional water during the surface finishing, as this will cause discoloration and / or cracking.
- Protect freshly applied material from freeze-thaw action.
- To avoid cracking in warm temperatures, keep bags cool and use cold water.
MIXING
Pour the required quantity of clean water (4.5 litres per 25 kg bag, or 180 litres per one tonne) into the mixing vessel for each complete unit of Parex 100 Newton Grout 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. For larger mixes, use 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 upmost importance that the product is mixed thoroughly enough that a grout consistency is obtained without the addition of further water (at least 3 minutes). 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 may be placed at temperatures between +5°C and +35°C.
For placing at temperatures outside this range, contact Sika® Technical Services Department for advice.
CURING TREATMENT
After the grout has initially hardened, remove formwork and trim edges while concrete is ‘green’.
Protect the fresh material from premature drying using an approved curing method (e.g. curing compound such as Sikafloor® ProSeal, moist geo-textile 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 TOOLS
Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
