proportionof the concrete mix shall be 1:1.5:3 (1 cement: 1.5 coarse sand: 3 graded stone aggregate 20 mm. nominal size) by

volume.Concrete work shall have fairly exposed concrete surface or as specified in the item. The designation ordinary M-10, M-

15, M-20,M-25 specified as per I.S. corresponds approximately to 1:3:6, 1:2:4, 1:1.5:3 and 1:1:2 nominal mix of ordinary

concrete, byvolume respectively. The ingredients required for ordinary concrete containing one bag of cement of 50 Kg. by

weight (0.0342m3.) for different proportions of mix shall be as per IS 456-2000. The proportion of the aggregate for the kerb

stone shall bemodified as per the approval of the engineer-in-charge. The water cement ratios shall not be more than those

specified as per IS.The cement of the mix shall be increased, if the quantity of water in a mix has to be increased to overcome the

difficulties ofplacement and compaction so that the water cement ratio specified in the table is not exceeded. The maximum size

of coarseaggregate shall be as large as possible within the limits specified but in no case greater than 1/4th of the minimum

ofthemember,providedthattheconcretecanbeplacedwithoutdifficultysoastosurroundallreinforcementthoroughlyandtofill the

corners of the form. For reinforced concrete work, coarse aggregates having a nominal size of 20 mm. are generallyconsidered

satisfactory. Admixture shall be used in concrete only with approval of the Engineer-in-charge based upon theevidence that with

the passage of time, neither the compressive strength of concrete is reduced nor are other requisite qualitiesofconcrete impaired

bythe useofsuch admixtures.

Proportioning shall be done by volume, except cement which shall be measured in terms of bags of 50 kg weight. The volume

ofone such bag can be taken as 0.0342 m3. Boxes of suitable sizes shall be used for measuring sand and aggregate. The size of

theboxes (internal)shall be 30cm.x30 cm.and38 cm.deep. While measuring the aggregate andsand,the boxshall be filledwithout

shaking ramming or hammering. The proportioning of sand shall be on the basis of its dry volume and in case of

dampsand;allowancesforbulkageshallbe made.

For all work, concrete shall be mixed in a mechanical mixer which along with other accessories shall be kept in first class

workingcondition and maintained throughout the construction. Measured quantity ofaggregate, sand, and cement required for

eachbatch shall be poured into the drum of the mechanical mixer while it is continuously running. After about half a minute of

dry-mixing, measured quantity of water required for each batch of concrete mix shall be added gradually and mixing continued

foranother one and a half minute. Mixing shall be continued till materials are uniformly distributed and uniform colour of the

Mixers which have been out of use for more than 30 minutes shall be thoroughly cleaned before putting in a newbatch. Unless

otherwise agreed to by the Engineer-in-charge, the first batch of concrete from the mixture shall contain only2/3rds of normal

quantityof coarse aggregate. Mixing plant shall be thoroughlycleanedbefore changingfrom one type ofcement toanother.

The degree of consistency which shall depend upon the nature of the work and methods of vibration of concrete shall

bedetermined by regular slump tests in accordance with IS: 1199-1959. The slump of 10 mm. to 25 mm. shall be adopted

whenvibratorsare used.

RemovalofMoulds:

Specific time shall be identified for removal of moulds, such that the concrete of the precast blocks shall gain strength

towithstand the stresses generated due to self weight and handling to drying yards without any deformation to shape/

dimensions/edges.

Sufficient time shall be given to the block after it is removed from the mould so that it can gain strength and dry in shade

toprevent anycracksdue to shrinkage. Thisshall be doneindryingyards.

Samplingandtestingofconcrete:

Samples from fresh concrete shall be taken as per IS : 1199-1959 and cubes shall be made, curedand tested at 7 days or

daysas per requirements in accordance with IS : 516-1959. A random sampling procedure shall be adopted to ensure that

eachconcrete batch shall have a reasonable chance of being tested i.e. the sampling should be spread over the entire period

ofconcretingandcoverallmixing units.

At least 1 sample shall be taken from each shift. Ten test specimens shall be made from each sample, 5 for testing at 7 days,

andthe remaining 5 at 28 days. The samples of concrete shall be taken on each day of the concreting as per above frequency.

Thenumber of specimens may be suitably increased as deemed necessary by the Engineer-in-charge when procedure of tests

givenabove reveals a poor quality of concrete and in other special cases. The average strength of the group of cubes cast for each

dayshall not be less than the specified cube strength of 200 Kg/cm2 at 28 days. 20% of the cubes cast for each day may have

valueless than the specified strength provided the lowest value is not less than 85% of the specified strength. If the concrete

made inaccordance with the proportions given for a particular grade, does not yield the specified strength, such concrete shall

beclassified as belonging to the appropriate lower grade. Concrete made in accordance with the proportions given for a

particulargrade shall not,however,be placedinahighergrade onthe ground thatthe teststrengthare higherthanthe

minimumspecified. If rock pockets/honeycombs in the opinion of Engineer-in-charge are of such an extent or character so as to

affect thestrength of the structure,materially or toendanger the life of the steel reinforcement, he may declare the concrete

defectiveand requirethe removalandreplacement oftheportionofthe structureaffected.

PrecastKerbStones:

The relevant specifications of concreting as per item above shall be followed except that work shall be carried out for

precastconcrete kerb stones as specified in the item. All Precast members shall be cast at workshop. Sufficient curing shall be

donebefore placement of the samethe method of transporting and placing the precast members shall be as approved by

theEngineer-in-charge. Members shall be so transported that no breakage or undue stresses are induced in them. If required,

allmembers shall have a key provided on both the faces i.e top and bottom surfaces, of adequate size so as to fill the same

manner and rolleduntil firmsurface isobtained.

Where the Wet mix macadam is to be laid on an existing metalled road, damaged area including depressions and potholes

shallbe repaired and made good with the suitable material. The existing surface shall be scarified and re-shaped to the required

Immediately after mixing, the aggregates shall be spread uniformly and evenly upon the prepared subgrade/sub-base/base

inrequired quantities. In no case should these be dumped in heaps directly on the area where these are to be laid nor shall

theirhaulingover a partlycompleted stretchbe permitted.

The mix may be spread either by a paver finisher or motor grader or as per instruction of Engineer-in-Charge and/or

hisauthorized representative. For portions where mechanical means cannot be used, manual means as approved by the

Engineershall be used.The motor grader shall be capable of spreading the material uniformly all over the surface. Its blade shall

In portions having unidirectional cross fall/superelevation, rolling shall commence from the lower edge and progress

Any displacement occurring as a result of reversing of the direction of a roller or from any other cause shall be corrected at

Along forms, kerbs, walls or other places not accessible to the roller, the mixture shall be thoroughly compacted with

mechanicaltampers or a plate compactor. Skin patching of an area without scarifying the surface to permit proper bonding of the

addedmaterialshall notbepermitted.

Rolling should not be done when the subgrade is soft or yielding or when it causes a wave-like motion in the sub-

base/basecourse or subgrade. If irregularities develop during rolling which exceed 12 mm when tested with a 3 metre straight

edge, thesurface should be loosened and premixed material added or removed as required before rolling again so as to achieve a
