SikaCem 130 Intraplast
Expanding grout admixture for cementitious injection grout
SikaCem 130 Intraplast Price in Bangladesh is a ready to mix expanding grout admixture in powder form for injection grouting. It is non-toxic, non-flammable and does not contain chlorides. 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 130 Intraplast has following advantages:
- Good compressive and bond strengths
- Improved fluidity
- Increased cohesion
Usage
SikaCem 130 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

Application steps
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.
- Water should be added to the mixer first, followed by Portland-cement and then admixture. Add sand where required.
- Using low speed high shear mechanical stirrer, mix thoroughly as to obtain a uniform, thoroughly blended grout, without excessive temperature increase.
APPLICATION
IMPORTANT- SikaCem 130 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 130 Intraplast Price in Bangladesh, 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
- 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.
