concrete produced in the Laboratory with the object or (I) designing a
concrete mix before the actual concreting operations designing a
concrete mix before the actual concreting operations start, (ii)
determining the adjustments required in the designed mix when there
is a charge in the materials used during the execution of work, or (iii)
verifying the strength of concrete mix.

WORK TEST:

A test conducted in an approved Laboratory, on the specimens made
on the work, out of the concrete being used on the works.

Note:2

In regard to the water-cement ratio for trial mix, reference may be made
to the graphs in Appendix A of IS: 456 –2000 given.

CRITERION REGARDING STRENGTH:

2.42 CLASSIFICATION OF CONCRETE OF LOWER OR HIGHER
STRENGTH THAN SPECIFIED:
Where the strength of concrete mix (for Ordinary Concrete or
Controlled Concrete), as indicated by tests, lies in between the
strengths of any two grades specified in Table 1, such concrete
shall be classified as a grade belonging to the lower of the two
grades between which its strength lies. In case the cube test
strength show higher strengths than those neither specified for
the particular grade nor shall contractor be entitled for any extra
payment on such account.
2.43 ORDINARY CONCRETE:
2.44 GRADES OF CONCRETE:
Ordinary concrete shall be used only of grades M-100, M-150 and M-
200. Controlled concrete shall be used for grades above M-250 and

respectively.
2.48 (a) WATER-CEMENT RATIO:

The water –cement ratios shall not be more than those specified in
Table II for concrete compacted without the use of Mechanical
vibrators. However, in order to overcome difficulties in placement and
compaction, if the contractor so desires, he can increase the quality
of water (beyond shat is indicated in table II), provided, at his own
expense he will increase quantity or cement also, to maintain water-
cement ratios within those specified in Table II.

(b) Since concrete shall be vibrated, the water-cement ratio limits
specified in Table II may be suitably reduced to avoid segregation.
Water – cement ratio of 0.45 by weight is suitable for Vibrate
Concrete and shall be adopted unless otherwise directed by
Structural Engineer.

(c)Allowance shall be made for surface water present in the aggregate
while computing the water content. Surface water shall be
determined by one of the field methods described in IS: 2386 (Part
III) 1963. In the absence of exact date, with the approval of the Site
Engineer the amount of surface water may be estimated from the
values given in Table III below.

TABLE III – SURFACE WATER CARRIED BY AVERAGE
AGGREGATE

Aggregate Approximate quantity of
Surface water in litre/m

Very wet sand 120
Moderately wet sand 80
Moist sand 40
Moist gravel or crushed rock 20 to40

2.49 WORKABILITY:
Workability of concrete should be controlled by making allowance for
any surface water in the fine and coarse aggregates. The slumps test
or compacting factor test shall be carried out at intervals as directed
by the Site Engineer. The slumps of 5 cm to 15 cm whilsh the
compacting factor test is suitable for 0 to 5 cm.
2.50 GRADING TEST:

Regular grading tests on fine and coarse aggregates shall be made and
any tendency to depart from specification requirements should be
corrected. It can be assumed as rough guide that from 45 percent to
75 percent of the total aggregate (fine plus coarse) should pass
through a sieve of aperture size equal to one half of the maximum size
of coarse aggregates. Research shows that combined aggregate
(maximum 20 mm size) graded between the following limits are
consistently satisfactory.

Sieve size Percentage passing (by weight)

20 mm mesh 100
10 mm mesh 55-65
4.75 mm mesh 35-42
2.36 mm mesh 28-35
1.18 mm mesh 21-28
600 micron 14-21
300 micron 3-5

97
While with some materials, it may not always be possible to obtain
combine gradings as specified above, the grading should never the
less be kept as close to the above grading as possible.

2.51 WEIGHING DEVICES:

The weighing devices should be maintained in a clean serviceable
condition and checked regularly with a view to keeping their accuracy.
The water guage should be properly cleaned and calibration regularly
checked.

2.52 STOCK-PILING AGGREGATES:

Unless otherwise directed, with a view to maintain uniformity of water
cement ratio, the aggregates shall be stacked in stockpiles. Where
stock piles are used, the floors should be clean. The stock-piles
should, as far as possible, be large, flat-topped and drained. It is
recommended that the aggregates should not be drawn from the
bottom 0.5 meters of the stock –pile, since this is normally much
better than that above.

2.53 SAMPLE SIZE AND ACCEPTANCE CRITERIA:

All tests shall be carried out in accordance with IS: 516-1959. The
number of tests specimens required, the frequency of sampling and
the criteria for acceptance of a concrete of a specified grade shall be
in accordance with the Table IV for „Ordinary Concrete‟.

2.54 MAXIMUM AGGREGARE CEMENT RATIO:

The maximum total quantity of combined aggregates (fine plus
coarse) by weight for 50kg Of cement shall not exceed 400 kg.

2.55 GRADING OF AGGREGATE:

The grading of aggregates shall be controlled by obtaining aggregates
in different single size aggregates stacked in separate stock piles and
blending them in the right proportions to obtain required grading to
conform to that used in mix design in preliminary tests.

98
2.56 STOCK PILING AGGREGATES:

The material shall be stock-piles for at least 24 hours before use. The
stock-piles, as for as possible be large, flat topped and drained. It is
recommended that the aggregates should not be drawn from the
bottom 0.5 meters of the stock-pile since this is normally much better
than that above.

2.57 GRADING TESTS:

The grading of coarse and fine aggregates shall be checked at
frequencies as specified or at more frequent intervals if so directed by
the Site Engineer, with the idea of ensuring that the grading of the
aggregates used on works corresponds to that used in samples in
preliminary tests.

2.58 BATCHING

Cement and aggregates shall be batched only by weight in a
mechanical weigh-batcher. Batching cement and water shall be as
specified in a paras 2.19 and 2.20 respectively.

2.59 WATER CEMENT RATIO:

It is most important to maintain the water-cement ratio constant at its
correct value I.E. at the value determined in the laboratory mix
design. To this end, determination of moisture contents in both fine
and coarse aggregates shall be made at frequencies, as specified or at
more frequent intervals if so directed by the Site Engineer. The
amount of the added water should be adjusted to compensate for any
observed variations in the moisture content.

2.60 DETERMINATION OF MOISTURE CONTENTS:

For the determination of the moisture content in the aggregates, IS:
2386 (part-1963 methods of Test for Aggregates for Concrete may be
referred to.

99
2.61 ADJUSTMENT FOR MOISTURE PRESENT ON BATCHING OF
AGGREGATES:

To allow for the variation in weight of aggregates due to variation in
the moisture content, suitable adjustment in the weights of
aggregates shall be made, while batching.

2.62 ALTERATIONS ON PROPORTIONS:

No substitutions in the materials used on the work of alterations in
the established proportions, except as permitted in para 2.64 above,
shall be made without proper revised design of mixes of tests.

2.63 WORKABILITY:

The workability of the concrete shall be checked at frequencies
specified or at more frequent intervals if so directed by the Site
Engineer. For work ability, slump test or compacting factor tests
shall be carried out. The slump test is suitable for slumps of 5 cm 15
cm and compacting factor test for slumps of 0 to 5 cm.

2.64 SOURCE OF CEMENT:

If possible, cement from same factory shall be used throughout the work.

2.65 SAMPLE SIZE AND ACCEPTANCE CRITERIA:

The number of test specimens required for the frequency of sampling and
criteria for acceptance of concrete as conforming to the specified concrete
grade shall be in accordance with Table V

2.66 WATERTIGHT CONCRETE:

Concrete in all basement works such as basement base slab and beams,
walls etc. water tanks and the like where concrete of m-200 grade or
richer is specified, will be considered as watertight concrete whether so
specifically mentioned or not in the Schedule of Quantities. In respect of
such concrete it shall be the Contractor‟s responsibility to ensure that
the resulting construction is watertight. If it is not, the contractor shall
carry out at his own cost, all necessary remedial measures which the
Architect directs.

100
2.67 FORM WORK:

2.68 MATERIALS AND DESIGN:

(a) The formwork shall be of timber or plywood or steel. If particular
material or materials be specified in the Schedule of Quantities for form
work such particularly specified material or materials shall be used in
work. The formwork shall be so constructed as to remain sufficiently
rigid during placing of the concrete and shall be sufficiently tight to
prevent loss of liquid from the concrete. The forms shall have sufficient
strength and rigidity to hold concrete and withstand the pressure of
ramming and vibration without excessive deflection of the prescribed
lines and more so when the concrete is vibrated. The surface of all forms
in contact with concrete shall be clean, rigid, water-tight and smooth.
Suitable devices shall be used to hold corners, adjacent ends and edges
of panels of other forms together in accurate alignment.

(b) The formwork shall conform to the shape, lines and dimensions to
suit the R.C.C. members a shown on drawings and to be so constructed.
Framework shall be adequately designed to support the full weight of
workers, fresh placed concrete without yielding settlement or deflection,
and to ensure good and truly aligned concrete finished in accordance
with the construction drawings. A camber in all directions of 6 mm. For
every 5 m span in all slab and beam centering shall be given to allow for
an unavailable sagging due to compression or other causes.

(c) The formwork shall be so designed that the sides of the beams shall
be first struck leaving the soffit of beams and the supporting props in
position. Props shall be designed to allow accurate adjustment and to
permit of their being struck without jarring the concrete.

(d) Temporary openings shall be provided at the base of column forms
and at other points where necessary to facilitate cleaning and
observation immediately before concrete is deposited.

(e) VERTICAL SHUTTERING: The vertical shuttering shall be carried
down to such solid surface as is sufficiently strong to afford adequate
support and shall remain in position until the newly constructed work is
able to support itself. Props shall be securely braced against lateral
deflection. Where timber props are used like bullies, they shall be of a
minimum diameter of 10 cm and shall be straight and adequately strong.
The spacing of such struts shall be designed to carry loads imposed on it

101
without undue deflection of the members supported by the props. The
spacing of props shall be approved by the Site Engineer and any
alteration suggested by him shall be carried out at contractor‟s expense.
Bracing shall be provided as directed without extra cost. Contractor shall
allow in his rates for providing props and struts for any height shown in
the working drawings issued to contractor from time to time.

2.69 WATERTIGHTNESS: It is the contractor‟s responsibility to ensure
that the forms are checked for water tightness just before concreting
operation starts and to make good any deficiencies.

2.70 CLEANING AND TREATMENT OF FORMS: All rubbish,
particularly chippings, shavings and sawdust shall be removed from
the interior of the forms before the concrete is placed and the form
work in contact with the concrete shall be cleaned and thoroughly
wetted or treated with approved composition. Care shall be taken that
such approved composition is kept out of contact with the
reinforcement.

2.71 STRIPPING:

Forms shall be left in place until their removal is authorised by the
Site Engineer and shall then be removed with care so as to avoid
injury to concrete. In no circumstances shall forms be struck until the
concrete reaches a strength of atleast twice the stress to which the
concrete may be subjected at the time of striking. The strength
referred to shall be that of concrete using the same cement and
aggregates, with the same proportions. And cured under conditions of
temperature and moisture similar to those existing on the work.
Where possible, the from work shall be left longer, as it would assist
the curing.

102
2.72 STRIPPINIG TIME:

In normal circumstances (generally where temperatures are above 20 c) and where
ordinary cement is used, forms shall be struck after expiry of the following periods.

Striking time in days for

Location Ordinary Pozzolana
Portland Cement
Cement
(a) Vertical sides of walls Slabs, Beams 2 3
and

(b) Bottoms span 7 14
of slabs up to 4.6M

2.73 FORMWORK IN LIFTS FOR CONTINUOUS SURFACES:

Where forms for continuous surface are placed in successive units, (as
for example in columns or walls), the forms shall fit tightly over the
completed surface so as to prevent leakage of mortar from the concrete
and to maintain accurate alignment of the surface.

103
2.74 PROCEDURE WHEN REMOVING THE FORMWORK:
The formwork shall be removed without such shock or vibration as would
damage the reinforced concrete. Before the soffit and struts are removed,
the concrete surface shall be exposed where necessary in order to
ascertain that the concrete has sufficiently hardened. Proper precautions
shall be taken to allow for the decrease in the rate of hardening that
occurs with all cements in the cold weather.
2.75 TOLERANCES:

reconstructing as decided by the Architect shall be borne by the
contractor. In case of work dismantled, the same shall not be
measured and paid for.

2.76 GENERAL
If in the Structural Engineer‟s opinion there is doubt as to the
strength of the structure due to the works test cubes failing to attain
specified strengths or due to poor workmanship like honeycombing
etc. or misplacing of concrete or similar circumstances or any reason
attributable to negligence on the part of the Contractor, then the
Structural Engineer‟s decision regarding dismantling of such concrete
or rectification, l if concrete is allowed to be retained in its place shall
be final and binding on the contractor.

104
2.77 WHERE CONCRETE IN STRUCTURE IN ALLOWED TO BE
RETAINED:
When the work strength as revealed by cube tests lies below the
specified strengths, if in the opinion of the Structural Engineer the
lower strength attained is acceptable to be retained in structure,
then for all purposes, including payment to the contractor such
concrete shall be classified as concrete below to the next lower grade
of concrete, (Refer Table No. l under para 2.41). For instance, if
concrete of grade M 200 obtained a strength at 289 days between
150 to 200 kg. Sq. cm. then the concrete will be classified as M. 150
and paid for accordingly.

2.78 CONCRETE ORDERED TO BE DISMANTLED: Where the
Structural Engineer does not accept the poor or defective concrete
and orders the same to be dismantled, then the Contractor shall
dismantle such concrete at his expense and reconstruct the same to
the Structural Engineer‟s satisfaction. Concrete thus dismantled will
not be measured and paid for.

2.79 CONCRETE RETAINED WITH RECTIFICATION:

Where the Structural Engineer in order to save time and where he
considers adequate, orders that defective concrete be strengthened
as directed by him, the contractor shall carry out all rectification
measures to Structural Engineer‟s approval at Contractor‟s expense.
The concrete of lower strength thus accepted shall, however, be paid
for after classifying the same as concrete belonging to next lower
grade (For grades of concrete refer Table I under para 2.41)

2.80 QUANTITY OF DEFECTIVE CONCRETE REPRESENTED BY
CUBES:

In all cases of defective concrete as revealed by works test cubes
strength falling below the specified strength, the quantity of concrete
thus affected and represented by the cubes shall be decided by the
Structural Engineer, whose decision shall be final and binding on
the contractor.

105
2.81 HONEY COMBING:

(a) Where honeycombed surfaces are notices in the concrete the
Contractor shall not patch up to same until examined by site engineer
and decision given regarding the acceptance with rectification or rejection
of the same. If contractor patches up such defects without the knowledge
of the site engineer, the Architect will be at liberty to order demolition of
the concerned concrete members to the extent he considers necessary. In
such case, the contractor at his expense shall reconstruct demolished
work. The demolished work shall not be measured and paid for.

(b) If in the opinion of the site engineer the honeycombing is harmful to
the structure and where so directed by the architect, the full structural
members affected by honeycombing as decided by architect shall be
dismantled and reconstructed to Architect‟s approval at Contractor‟s
expense. The demolished concrete will not be measured and paid for.

(c) Where in the opinion of the Site Engineer the structural members
containing honeycombing can be allowed to be retained with rectification,
the rectification, shall be carried out as directed by the Structural
Engineer by guniting (with cement mortar 1:3 proportion) the areas
concerned at Contractor‟s expense.

(d) Such honeycombed areas which are not severe in the opinion of Site
Engineer and where so directed shall be patched up with cement mortar
consisting of I part of cement to 2 parts of sand after removing defective
concrete down to sound concrete to the satisfaction of Site Engineer, all
at the expense of contractor.

2.82 LOAD TESTING:

The Architect reserves the rights to reject any load testing on structures
and proceed to deal with defective concrete as stated in the above
paragraphs. However, purely at his discretion, he may instruct the
contractor to make a loading test on the work or part thereof. The nature
of the test and the loading shall be left to the discretion of the Architect.
The contractor shall bear the cost of the test and the cost of dismantling
and reconstructing or correcting the defects by rectification in
accordance with his instruction. Where such structure is allowed to be
retained in the work the concrete shall be devalued to the next lower
grade and payment made accordingly to the contractor (Refer to Table
No.1 for grades of Concrete).

Chlordane 1.0% ( “ )
Dieldrin 0.5% ( “ )
Deptachlor 0.5% ( “ )

2 TREATMENT OF COLUMN PITS WALLS TRENCHES AND BASEMENT
EXCAVATIONS:
The bottom surface and slides (up to a height of 30 cm. from the bottom)
of the excavations made for column pits, trenches and basements shall
be treated with to chemical emulsion mentioned above at 5 liters per.
Meter of surface area.
3 TREATMENT TO BACKFILL EARTH:
After the column foundations, wall foundations and retaining walls of the
basement come up, the backfill in immediate contact with the foundation
structure shall be treated with the chemical emulsion at the rate of 15
litres/m2 of the vertical face of the sub-structure of each side. The earth
is usually returned in layers and treatment shall be carried out in similar
stages. The chemical emulsion shall be directed towards the concrete or
masonry surface of the columns and walls so that the earth in contract
with these surfaces is well treated with chemicals.
4. TREATMENT TO R.C.C. FRAMED STRUCTURES:
The treatment described in 2 and 3 above applied essentially to masonry
foundations where there are voids in the joints through which termites
can seek entry into the superstructure. Hence the foundations require to
be completely enveloped by a chemical barrier. In the case of R.C.C.
framed structures with columns and plinth beams and R.C.C. basements
the concrete mix is rich and dense (being 1:2:4 or M 150 or richer), it is
unnecessary to start the treatment from the bottom of excavation for
start at a depth of 50 cm. Below ground level from this depth, the backfill
around the columns beams and R.C.C. basement walls shall be treated
at the rate of 15 litres/m2 of the vertical surface. The other details of the
treatment shall be as laid down in 3 above.

earth shall be treated with chemical emulsion at 5 litres per sq.metre.
Light rodding of the surface may be carried out to facilitate proper
absorption of the emulsion.
6. TREATMENT AT JUNCTION OF WALLS AND FLOOR:
Special care shall be taken to establish continuity of the vertical
chemical barrier on inner wall to surfaces from the ground level
(where it had stopped with the treatment described in 3 above) upto
the level of the filled earth surface. To achieve this, a small channel 3
x 3 cm., shall be made at all junctions of wall and columns with the
floor ( before laying the sub grade) and rod holes made in the channel
upto the ground level 15cm. Apart and the rod moved backward and
forward to break up the earth and chemical emulsion poured along
the channel at the 5 litres per linear meter so as soak the soil right to
the bottom. The soil should be tamped back int place after this
operation.
7. TREATMENT TO SOIL ALONG EXTERNAL PERIMETER OF
BUILDING:
Finally the earth round the external perimeter of the building upto a
depth of 30cm shall be treated at the rate of 4.5 litres per running
metre of plinth wall. To facilitate this treatment, solid M.S. rods
should be driven into the soil as close as possible to the plinth wall at
intervals of 15 cm and upto a depth of 30 cm. And the rods moved
backwards and forwards in a direction parallel to the wall to break up
the earth so that the chemical emulsion mixed intimately with the
soil.
8 TREATMENT OF SOIL SURROUNDINGS PIPES, WASTES AND
CONDITS:
When pipes, wastes and conduits enter the soil inside the area of the
foundations, the soil surroundings the point of every must be
loosened around each such pipe, waste or conduit for a distance of 15
cm. And upto a depth of 7.5 cm before treatment is commenced.
When they enter the soil external to the foundation, they shall be
similarly treated unless they stand clear of the walls of the building by
about 7.5 cm for a distance of over 30 cm.
