Connect jack to hydraulic pump.
At the beginning of stressing the strands are locked in the jack pulling
head.
The pressure readings and the measured elongation are recorded in
the stressing report.
Stress initially to10Mpato remove slack in the strands.
Proceed stressing and record the strands’ elongation for every
incremental of 10MPa pressure.
When the jack has reached the end of its stroke or the desired force
has been obtained, the pressure in the jack is released and the strands
will locked uniformly by the wedges in the wedge plate.
The jack piston returns.
Stressing is continued in as many stages as are necessary to obtain
the required forces.
Note:De-Shuttering at pour strip area can be carried out after completion of
concreting in that area and after achievement of required compressive strength.

After the stressing and trimming of strands are completed, sealingof
tendons recesses will be doneusing cement mortar as per specifications.
Water will be potable,free from impurities and cement(OPC–53 grade)
willbe used andthe same should befreefrom anylumps.
Water and cement will be mixed as per the details given in the Codal
specification using mixer andagitate the mix continuously.
TheW/cratio will be kept as 0.45 and mixing time of grout willbe 2–3
minutes and approved non-aluminum based expanding agent may be
added as per Codal specifications.
Grout in the collection drum willbe kept in continuous slow agitation by
meansof agitator until pumped into the duct.
Grout will be pumped into the duct by inlet.
Start filling the duct with the specified grout mix, consistency ofthe grout
hasto be checked from the other end grout vent, and if it reaches the
same, close both the vent. Build the grout pressure from 3 to 5kg/cm2
and maintain the pressure for 15-20 seconds and seal the other end by
tying with binding wire.
The inlet will be closed and pressure willbe released from grout pump by
releasing thereturn valve in the groutpump.
Same procedure willbe adopted for remaining cables.
During grouting workers will wear protective goggles, helmets, and hand
gloves.
All the data willbe recorded in the format.

38. Instructions for use

Mixing

For best results Fosroc MR3 mixer must be used. For
quantities up to 50 kg a slow speed drill fitted with a high
shear paddle is suitable. Larger quantities will require a high
shear vane mixer.

It is essential that machine mixing capacity and labour
availability is adequate to enable the grouting operation to be
carried out continuously. This may require the use of a holding
tank with provision for gentle agitation to maintain fluidity.

The selected water content should be accurately measured
into the mixer. Slowly add the cement (and sand if required)
and Cebex 100. Mix continuously for 5 minutes, making sure
that a smooth even consistency is obtained.

Application

Areas to be grouted should be prepared to ensure substrates
are clean, sound, and then pre-wetted. The unrestrained
surface area of the grout must be kept to a minimum. Place
the grout within 20 minutes of mixing to gain the full benefit
of the expansion process. Adopt usual placing or pumping
procedures ensuring a continuous operation.

Curing

On completion of the grouting operation, any exposed areas
which are not to be cut back should be thoroughly cured by
means of water application, Concure* curing membrane or
wet hessian.

Cleaning

Grouts mixed with Cebex 100 should be removed from tools
and equipment with clean water immediately after use.
Remove cured material mechanically or with Fosroc Acid Etch.

Limitations

Cebex 100 is not compatible with High Alumina Cement.
Estimating

Supply
Cebex 100 : 5 kg packs & 225 g tins

Dosage
OPC Concreting Water Conbex Approx
sand 100 yield
50 kg - 20-22 litres 225 g 36 litres
50 kg 50 kg 22-24 litres 225 g 57 litres

Note: For grout, mortar or concrete mixes with an aggregate/
cement ratio more than 1, use 4x225 g units or 900 g
of Cebex 100 per 100 kg of cement.

Effects of overdosing

Overdosing of Cebex 100 increases expansion and may cause
frothing.

Storage

Cebex 100 has a shelf life of 12 months if kept in a dry store in
its original packaging. High temperature and humidity storage
may reduce this period.

Precautions

Health and safety

Cebex 100 is of low hazard.

Contact with the skin and eyes, or inhalation of dust should
be avoided. Wear suitable protective clothing, gloves, eye/
face protection and dust mask. After contact with skin, wash
off with clean water. In case of contact with eyes, rinse
immediately with plenty of water and seek medical attention.

System Acceptance Test :
Anchorage Efficiency Test
Objective of the test:
This test is conducted to check and verify the performance of t he
anchorage assembly and to determine any decrease in breaking load of the
Pre–Stressing steal (Strands)due to the influence of the anchorage, and to
observe the elongation and behavior of the wedges.
Test Remarks:
The test will be conducted at any of the reputed lab based on the
requirement which satisfy FIP recommendations.
Frequency:
Theentire test is related to SF system policy and will be conducted
once in a year.
Load TransferTest
Objective of the test:
This test is conducted to verifythe transfer of the pre stressing force
from the mechanical anchorage and its competency to the concrete without
any failure in the anchorage assembly.
Test Remarks:
The test will be conducted at any of the reputed lab based on the
requirement which satisfy FIP recommendations.
Frequency:
Theentire test is related to SF system policy and will be conducted
once in a year.
