BAHAN INJEKSI GROUTING SUNTIK BETON KROPOS DAN BOCOR

Intraplast® Z BAHAN UNTUK CAMPURAN CAIRAN SEMEN UNTUK INJEKSI GROUTING

Expanding Grout Admixture

Description An expanding grout admixture in powder form. By introducing micro bubbles into

the mix, it produces wet volume expansion and increased fluidity without

segregation

Uses Intraplast Z is used to increase cohesion in cement grouts and is suitable for use in

the grouting of :

■ Pre-stressed cable ducts.

■ Rock and soil anchoring.

■ Bearing plates.

■ Pre-placed aggregates.

■ Tunnel linings.

■ Pre-cast concrete elements.

■ Tilt construction wall panels.

■ Crack injection.

Advantages

■ Intraplast Z plasticises the mix with water reduction of up to 20%, thus

improving the strength of the grout.

■ Gas generated during setting distributes bubbles causing expansion to take

place (3%-8% by volume) thus compensating for normal shrinkage.

The initial retarding effect of Intraplast Z improves grout penetration, reduces

water separation and bleeding.

■ The expansive forces generated completely fill voids.

■ Non toxic, non chloride.

Dosage 1- 2%

Typical Dosage 1.5%

Instructions for Use Add directly to the gauging water and mix with cement.

The mixture must be stirred continuously.

For pre-stressed concrete work, a mixing time of 3 minutes with a w/c ratio of 0.42

has been found to give the best results.

It is not recommended to add sand into the mix.

Technical Data

Form Powder

Colour Beige

Bulk density Approx. 0.7 kg / ltr

Shelf life 1 year if stored in unopened original container in dry, cool place

Packaging 20 x 0.75 kg bag

Remarks

■ High alumina cement and cement containing high content of fly-ash are not

suitable for use with Intraplast Z

■ To obtain optimum results (flowability, expansion, bleeding, etc) the suitable

w/c ratio and Intraplast Z / cement ratio shall be determined through trial mixes.

Handling Precautions

■ Avoid contact with skin and eyes.

■ Wear protective gloves and eye protection during work.

■ If skin contact occurs, wash skin thoroughly.

■ If in eyes, hold eyes open, flood with warm water and seek medical attention

without delay.

SikaSet® Accelerator

Set Accelerating Admixture

Description A concentrated solution of accelerating, plasticizing, and shrinkage-reducing

agents. It is added to Portland cement to produce quick setting mortar.

Use To produce quick setting, low shrinkage, high strength concrete patches.

It can be used for sealing leakages and for plugging water infiltrations in concrete.

Advantages Rapid set time

Low shrinkage

Good adhesion

High early strength &

Surface Preparation Chip away deteriorated, unsound substrate

Clean cavity completely.

Mixing SikaSet is to be used with fresh compressive strength.

Dosage Added to the mixing water within the range 1:0 – 1:5

Instructions for Use

Portland cement.

Actual initial and final setting time will vary with different brands of cement and job

conditions, test with small quantities of cement to be used should be conducted on

job site to determine proper dilution ratio for the desired setting time.

Application As Waterplug

Plug cement paste into crack or hole. Hold in place with hand, until it has hardened.

As Dry Pack Mortar

Used for patching concrete structures.

Dry pack mortar is made with 1 part OPC + 2 sand + SikaSet diluted with 2 to 5

parts water, depending on setting time desired.

Technical Data
