SikaCem®-135 Intraplast®

Aluminium free expanding grout admixture for cementitious injection grout

SikaCem®-135 Intraplast® is a ready to mix expanding grout admixture in powder form for injection grouting. It is aluminium free and does not produce hydrogen on reacting with water. It is non-toxic, non-flammable and does not contain chlorides or other ingredients of corrosive nature. It is used to increase fluidity and cohesion in cement grouts (addition of sand is possible) without any segregation and to develop non-shrink property. By introducing micro bubbles into the concrete mix, it produces wet volume expansion and hence is widely used for cable grouting. Suitable for use in hot and tropical climatic conditions.

The cement grout containing SikaCem®-135 Intraplast® has following advantages:
  • Good compressive and bond strengths
  • Improved fluidity
  • Increased cohesion
  • Volume expansion in the wet state to develop non shrink property
  • No chloride or other ingredients of corrosive nature
  • Non-toxic and non-flammable
  • Prevents premature setting
  • Reduces the amount of gauging water
  • No bleeding
  • Initially retarding
  • Free from aluminium powder, no hydrogen produced

Usage

SikaCem®-135 Intraplast® is mainly used for injection and grouting work where tight filling and strong interface bond is required such as for:
  • Anchor grouting
  • Pre-stressed cable ducts
  • Crack injection
  • Rock and soil anchoring
 
  • Pre-placed aggregates
  • Tunnel linings
  • Bearing plates
  • Soil or concrete consolidation
  • Pre-cast concrete elements

Specific Advice

Use Ordinary Portland Cement (OPC)

Mortar mix design

IMPORTANT

Design mixes should always be tested to verify satisfactory performance, specifically as it relates to strength, bleed, flow and segregation.

Indicative performance of mortar mix

IMPORTANT

The properties of the injection grout can be significantly influenced by the mixing procedure, cement properties, addition of water, addition of sand and temperatures. For type of application, it is necessary to determine the most suitable procedure by means of preliminary site tests.

IMPORTANT

Different cement would show different expansion, field testing should be conducted to determine the most effective dosage rate.

MIXING

IMPORTANT

Typical water-cement ratio 0.35 to 0.45

IMPORTANT

The mortar temperature should not exceed +25 °C. Use chilled water in hot climates for mixing.

IMPORTANT

Do not add water to the grout to increase any flowability which has been lost by delayed use of grout.

IMPORTANT

For efficient mixing of grouts, use a colloidal mixer. In large volume grouting, install an agitator tank beside the colloidal mixer to hold the grout before grouting.

IMPORTANT

Do not add sand when using the product in prestressing.

  

  1. Water should be added to the mixer first, followed by Portland-cement and then admixture. Add sand where required.
  2. Using low speed high shear mechanical stirrer, mix thoroughly as to obtain a uniform, thoroughly blended grout, without excessive temperature increase.

APPLICATION

IMPORTANT

SikaCem®-135 Intraplast® is essentially a product for use by specialists working in the field of pre-stressing and grouting techniques.

IMPORTANT

All pumps and hose fittings should be absolutely watertight to prevent loss of water and subsequent clogging.

IMPORTANT

In order to make maximum use of the expansion, use the mixture within 30 minutes. The batch size must be limited accordingly.

IMPORTANT

Do not use as non-shrink admixture for conventionally placed concrete.

          

    FORMING

    • Where areas to be grouted require forming, forms should be tight and well fitted.
    • When using SikaCem®-135 Intraplast®, expansion of the grout should be restrained in order to produce the highest possible density, bond and strength.
    • Top forms should be used where there are open areas. Note: Unformed, exposed grout placements will have substantially lower physical characteristics.
     

    PLACING

    1. The normal means of placing and pumping of grouting material should be used to ensure a continuous flow.

    CLEANING OF TOOLS

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