other allied expenses so incurred and as to the value of the work so done

departmentally shall be final and conclusive against the contractor.

DRIVING

The boring tool shall be centered at the exact pile location. Boring and driving shall then

proceed alternatiely till the appropriate strata is reached when the casing is being drien

care shall be taken to check that it is truly vertical. Sequence of boring and driving or vice

versa will depend upon the strata passed through. The item will cover boring and driving

the casing through all strata softer then rock. The contractor will not be entitle to any

compensation or extra rate if the depth to which pile are required to be driven are increase

or decrease.

Contractor will be responsible for any compensation that may have to be paid due to

injury to persons or damage to work and properly caused by this pile driving operation.

When the boring is done to satisfactory strata according to plan and approved by the

Engineer and casing filling driven to the required depth all loose material existing at the

bottom of the hole after completing the boring operation shall be removed before pouring

concrete.

Water may be used in the boring operation only to the extent absolutely necessary for

facilitating boring. All necessary steps shall be taken to prevent surface water from

entering the hole and all water which may have in filtrated into the holes shall be

removed before pouring concrete. If necessary the inside of the pile shall be inspected by

lowering light and it should be seen that any material like earth clay etc. sticking to the

casing is removed.

permitted by the purchaser.

4. APPLICATION OF COATING:

The coating shall be applied as an electro statically charged dry powder sprayed

on to the grounded steel bar using an electrostatic spray gun. The powder may be

applied to either a hot or cold bar. The coated bar shall be given a thermal

treatment specified by the manufacturer of the epoxy resin which will provide a

fully cured finish coating. Temperature shall be controlled as recommended by

the manufacturer of the coating to ensure a workman like job without blistering or

other defects.

5. REQUIREMENTS OF COATED BARS:

Coating Thickness:

For acceptance purposes atleast 90 percent of all coating thickness measurements

shall be 0-1 mm to 0-3 mm after curing. The coating thickness limits do not apply

to patched areas. A minimum of 15 measurements shall be taken approximately

evenly spaced along each side of the test bar. At least 90 percent of these

coating thickness measurements using magnetic gauges shall be used.

Pencil type pull-off gauges which require the operator to observe the reading at

the instant the magnet is pulled from the surface and do not hold shims tightly

against the steel plate during calibration are not recommended for use.

Gauge calibration with shims shall be performed on a smooth, clean, low-carbon

steel plate (at least 75 x 75 x 13 mm) rather than on a clean reinforcing bar.

A correction factor defining the effect of the bar preparation process shall be

obtained as the difference between (a) the average of the 10 gauge reading on a

cleaned but uncoated reinforcing bar of the size and lot being coated and (b) the

average of 5 gauge readings on a smooth mild steel plate. This correction factor

shall then be subtracted from all subsequent gauge readings on coated bars.

Fixed probe gauges shall be checked to ensure that the force generated by the

spring loaded probe housing is sufficient to ensure intimate contact between the

probe housing is sufficient to ensure intimate contact between the probe tip and

the coating on the curved bar surface if intimate contact does not result it will be

necessary to remove the probe housing and utilize hand-pressure to obtain valid

indicated thicknesses.

2. REINFORCING STEEL

Steel reinforcing bars to be coated shall conform to IS:1786:1985.


3. SURFACE PREPARATION:

The surface of the steel reinforcing bars to be coated shall be cleaned by abrasive

blast cleaning to near white metal. The surface profile shall be free from mill

scale, rust and foreign matter when viewed under well-lit conditions.

The coating shall be applied to the cleaned surface as soon as possible after

cleaning. Any formation of rust blooms on the cleaned bars are to be removed by

blast cleaning before application of the coating. However, in no case shall the

coating be delayed more than eight hours after cleaning unless otherwise

permitted by the purchaser.

4. APPLICATION OF COATING:

The coating shall be applied as an electro statically charged dry powder sprayed

onto the grounded steel bar using an electrostatic spray gun. The powder may be

applied to either a hot or cold bar. The coated bar shall be given a thermal

treatment specified by the manufacturer of the epoxy resin which will provide a

fully cured finish coating. Temperature shall be controlled as recommended by

the manufacturer of the coating to ensure a workman like job without blistering or

other defects.

5. REQUIREMENTS OF COATED BARS:

Coated Thickness

For acceptance purposes at least 90 per cent of all coating thickness

measurements shall be 0-1 mm to 0.3 mm after curing. The coating thickness

limits do not apply to patched areas. A minimum of 15 measurements shall be

taken approximately evenly spaced along each side of the test bar. At least 90 per

cent of these measurement shall be within the specified limits.

NOTE: By mutual agreement between the purchaser and the manufacturer,

thicker coating may be accepted where the bars are not to be bent on worked after

the coating has been applied.

CONTINUITY OF COATING:

The coating shall be visually inspected after curing for continuity of the coating and shall

be free from holes, voids, contamination, cracks and damaged areas discernible to the

unaided eye. In addition there shall be not more than an average of two holidays per 300

mm when tested in accordance with 8.2

Note : Holiday means a pinhole not discernible to the unaided eye.

ADHESION:

The adhesion of coating shall be evaluated on a representative number of bars selected in

accordance with 9.4 from each production lot. No visible cracks or disbanding in the

coating on the outside radius shall be allowed when tested in accordance with 8.3


6. TEST METHODS:

The thickness of the coating shall be measured on the body of reinforcing bar

between deformations and ribs or both, on a straight length. Non-destructive

coating thickness measurements using magnetic gauges shall be used.

‘Pencil’ type pull-off gauges which require the operator to observe the reading at

the instant the magnet is pulled from the surface and do not hold shims tightly

against the steel plate during calibration are not recommended for use.

Gauge calibration with shims shall be performed on a smooth, clean, low-carbon

steel plate (at least 75 x 75 x 13 mm) rather than on a clean reinforcing bar.

A correction factor defining the effect of the bar preparation process shall be

obtained as the difference between (a) the average of the 10 gauge readings on a

cleaned but uncoated reinforcing bar of the size and lot being coated and (b) the

average of 5 gauge readings on a smooth mild steel plate. This correction factor

shall then be subtracted from all subsequent gauge readings on coated bars.

Fixed probe gauges shall be checked to ensure that the force generated by the

spring loaded probe housing in sufficient to ensure intimate contact between the

probe tip and the coating on the curved bar surface. If intimate contact does not

result, it will be necessary to remove the probe housing and utilize hand pressure

to obtain valid indicated thicknesses.

HOLIDAYS:

A 67.5 volts holiday detector shall be used in accordance with the detector

manufacturer’s instructions. The detector may be an in line DC detector or a hand held

DC detector.

ADHESION OF COATING:

The adhesion of the coating shall be evaluated by bending production coated bars 120

degrees (after rebound) around a mandrel of size as prescribed in Table 1. The bend test

shall be made at a uniform rate and shall take upto 90 seconds to complete. The two

longitudinal deformations shall be placed in a plane perpendicular to the mandrel radius

and the test specimen shall be at thermal equilibrium between 250 and 35

0C.

NOTE : The fracture partial failure of steel reinforcing bar in the bend test for adhesion

of coating shall not considered as an adhesion failure of the coating.

every twenty bars for each size.

Continuity of coating shall be determined by testing one full length be in every

twenty bars for each size.

Coating thickness over the whole of the coated bar section shall be determined by

sectioning and examining one bar in every twenty tonnes for each size.

For testing adhesion of coating, samples shall be selected from each size

according to the frequency given below:

Nominal size of Bar (mm) No. of Samples

Upto 16 1 for every 1 tonnes

Above 16 and upto 25 1 for every 2 tonnes

bands shall be padded or suitable banding shall be used to prevent damage to the coating.

All bundles of coated bars shall be lifted with a strong back, spreader bar, multiple

supports, or a platform bridge to prevent bar-to-bar abrasion from stags in the bundles of

coated bars. The bars or bundles shall not be dropped or dragged.

The identification of all reinforcing bars shall be maintained throughout the

fabrication and coating processes to the point of shipment.

10. INSPECTION:

All tests and inspection shall be made at the place of manufacture prior to

shipment, unless otherwise specified.


PERMISSIBLE COATING DAMAGE AND REPAIR AFTER COATING

APPLICATION:

Coating damage due to fabrication and handling need not be repaired in case where the

damages area is 40 mm2 or smaller.

All damaged areas larger than 40 mm2 shall be repaired with patching material.
