SPECIFICATION FORSTRUCTURAL GRANITE

Fi rst Rev i si on0. F 0 R E W O-R D

0~1 This Indian Standard ( First Revision) was ado ed by the IndianStandards Institution on 15 March 1974. after the draft finalized by theStones Sectional Committee had been approved by the Civil EngineeringDivision Council.0.2 Granite is an important structural and ornamental stone and because ofits high compressive strength and durability, is extensively used for massivestructural works like bridge piers, sea and river walls, dams and monumentalbuildings, where excessive wear and abrasion is likely to occur. Fine graincdvariety of granite that takes and preserves high polish and is susceptible ofbeing carved is employed for ornamental and monumer&l works and also forinscription purposes. Granite is found in several parts of India with slightvariations in the physical properties of the stone depending upon the grainsize and the minerals that go into its formation. This standard has, therefore,been formulated with a view to specifying suitable grades of granite stone andproviding necessary guidance in the selection of proper grade of granite for agiven specific job.0.3 Granite is available in different colours mostly in grey, mottled grey, red,pink, dark blue, white or green depending upon the colour of the componentminerals. The designer shall, thcreforc, specify the colour desired and thepermissible natural variations in rolour and texture in detail or by namingthe granite having the required rharactcristics. Granite containing injuriousmincraIs like pyrites nud marcasite which upon exposure. rust rapidly andcause ob_jectionable strain on the stone shall be excluded. This st+ndard wasfirst pubhshcd in 1965 which covered sampling and grading aspects only. Inthis revision requirements for strength, dimension3 marking, etc, have beenincluded.0.4 For the purpose of deciding whether a particular reauirement of thisstandard is complied with, the final value observed or calculated, expressingthe result of a test or analysis, shall be rounded off in accordance with

1. SCOPE1.1 This standard covers selection, grading and strength requirements ofstructural granite for the various constructional UXS.2. GENERAL REQUIREMENTS2.1 Granite shall be free from flaws, injurious veins, cavities and similarimperfections that would impair its structural integrity and would adverselyaffect its strength and appearance.3. STRENGTH REQUIREMENTS3.1 The compressive strength when tested according to IS : 1121-1974t shallbe not less than 1 000 kg/cm2.3.2 The specific gravity when tested according to IS : 1122-1974 shall notbe less than 26.3.3 The water absorption when tested according to IS : 1124-19749 shall notbe more than 050 percent.4. DIMENSIONS4.1 Slabs

4.1.1 The slabs shall be rectangular or square and of specified dimensions.The tolerance in length and breadth shall be f2 mm and thickness f 1 mm.The bottom.face may be rough but the top surface shall be fine dressed andjoint faces shall be dressed back square with the top surface for at least50 mm, without hollowness or spalling off.4.2 Blocks for Masonry - The dimensions of the blocks shallspecilied. The tolcrancc shall be allowed f5 mm for facing blocks. % zedges of the blocks shall be dressed according to IS : 1129-197211.

5.1.1 Each type of blocks and slabs may also be marked with the ISICertification Mark.NOTE - The use of the IS1 Certification Mark is governed by the provisions of theIndian Standards Institution (Certification Marks 1 Act and the Rules and Regu-lations made thereunder. The IS1 mark on products covered by an Indian Standardconveys the assurance that they have been produced to comply with the require-ments of that standard under a well-defined system of inspection, testing and qualitycontrol which is devised and supervised by IS1 and operated by the producer. IS1marked products are also continuously checked by IS1 for conformity to that

standard as a further safeguard. Details of conditions under which a licence for theuse of the IS1 Certification Mark may be granted to manufacturers or processors, maybe obtained from the Indian Standards Institution.6. SAMPLING6.1 Lot - In any consignment all the blocks/slabs of the same quarry shallbe grouped together to constitute a lot.

6.1.1 Samples shall be selected and tested separately for each lot fordetermining its conformity or otherwise to the requirements of thespecification.6.2 The number of blocks/slabs to be selected for the sample shall dependupon the size of the lot and shall be in accordance with Table 1.

6.2.1 The blocks/slabs in the sample shall be selected at random and inorder to ensure the randomness of selection, random number tables may beused ( see IS : 4905-1968* ) .6.3 All the blocks/slabs selected in accordance with co1 2 of Table 1 shall beexamined for general requirements and dimensions ( see 2 and 4 ).

A lot shall be considered as conforming to thoserequirements if the number of defective blocks/slabs obtained is not morethan the permissible number of defectives given in co1 3 of Table 1.6.4 The lot having been found satisfactory with respect to dimensions, andgeneral requirements shall be tested for physical properties. For this purposea sub-sample of size given in co1 4 of Table 1 shall be selected at random.These blocks/slabs in the sub-sample shall be first tested for compressionstrength, the same samples after completion shall be utilized for determiningwater absorption, and specific gravity see 3 ). A lot shall be consideredhaving been satisfied the requirements of the physical properties if none ofthe blocks/slabs tested for these rcquircments fails in any of these tests.
