SikaGrout®-212 HP AU

DUAL SHRINKAGE COMPENSATED HIGH STRENGTH CEMENTITIOUS GROUT FOR APPLICATIONS FROM 10MM TO 100MM.

SikaGrout®-212 HP AU is a cementitious, non-shrink, high performance grout that expands in two stages in both the plastic and hardened states (class A and C) to counteract the shrinkage normally associated with cement grouts.

Characteristics and advantages include:
  • Shrinkage compensating properties, classed as a nonshrink grout as per ASTM C1107.
  • High 28 day strengths.
  • Flowable consistency.
  • Adjustable consistency.
  • Formulated to not segregate or bleed.
  • Excellent impact and thermal resistance.
  • Non corrosive to steel or iron.
  • Lab tested in accordance with AS 1478.2

Application steps

EQUIPMENT

SikaGrout®-212 HP AU must be mechanically mixed using a mechanical grout mixer or a suitable drum mixer. The grout mixer will reduce the chances of the mix becoming lumpy or aerated. Smaller quantities should be mixed in clean drum using an electric drill and spiral drill and spiral mixer at a speed of approximately 500 rpm.
DO NOT MIX BY HAND.

MIXING

  1. Plastic grout, add 2.8 L - 3.2 L of water per 20 kg bag. Flowable grout, add 3.3 L - 3.7 L of water per 20kg bag.
  2. Add the powder component to approximately 70% of the total amount water component while mixing.
  3. Add the remaining 30% of the water component to the grout at a steady rate while continuing to mix.
  4. Mix until the grout appears homogenous (3-5 minutes). Allow to stand so any entrapped air can escape. Do not add more water to increase flow of the grout if a mix has stiffened due to time delays. If the grout is unworkable discard.

APPLICATION

SikaGrout®-212 HP AU can be placed by gravity flow or by pump. It is essential that proper placing on the job site is practised to ensure placement is completed without problems. Sufficient labour, grout and equipment must be present to ensure continuous placement.
Gravity Flow
Mixed grout should be poured one side of the void to avoid air entrapment. Grout is best poured over short distances to ensure this. Use a suitable header box, maintaining the grout head at all times to ensure continuous flow. To facilitate grout compaction and top plate contact, use rodding, tamping or flexible strapping in short strokes while maintaining an adequate head of grout. Do not vibrate as this will cause segregation. Any adjacent machinery or equipment causing vibration should be shut down until initial set (5 to 6hours).

Pumping
When pumping SikaGrout®-212 HP AU, ensure the pump is suitable for the grout consistency and for the distance and height it is to be pumped. A positive displacement pump is recommended. Place grout by pumping into the farthest corner, filling the space gradually. Ensure that air is not entrapped under the base plate.

CURING TREATMENT

Suitable curing methods such as plastic sheet, wet hessian, curing compounds (eg, Sika Film for initial placement then Sika Antisol curing compoundsafter initial set) etc. must be used to protect the freshly applied grout from the drying effects of sun and wind. Curing must commence immediately after placement, and continue for at least 7 days. Curing is vital to the ultimate performance of grout as it allows optimum strength development and ensures tight contact with the baseplate.

CLEANING OF EQUIPMENT

Remove uncured SikaGrout®-212 HP AU from tools and equipment with water. Hardened material can only be removed mechanically.
