Indian StandardSPECIFICAnON FOR
MOULDS FOR USE IN TESTS OFCEMENT AND CONCRETE
o. FO R E W OR D
0.1 ThIS Indian Standard was adopted by the Indian Standards Institutionon 28 January l 982, after the draft finalized by the Cement and ConcreteSectional Committee, had been approved by the CI\ 11 Engmeenng DIVISIonCouncil.
0.3 The Indian Standards Instttutton has already published a sene, ofstandards on methods at' tc.nng cement and concrete. It has beenrecognized that reproducible and repeatable test results can be obtainedonly With standard tesung equipment capable of givmg the desired levelof accuracy The Secuonal Committee has, therefore. decided to bnng outa sene, of specIficatIons covering the require-nents of equipment used fertesting cement and concrete, to encourage their development and manufacture in the country.
0.3 Accordingly, this standard has been prepared to cover requirements ofthe moulds used for c.isung cement or concrete cubes, cylinders and beamsfor compressive and flexural strength tests on cement and concrete. TheIndian Standards which detail the method, of compressive and ftexuralstrength tests requiting use of these moulds are IS: 516-1959.,IS: 1I99-1959t and IS : 4031-1968t-
0.4 In the formulatton of tlus standard, due werghtage has been given tomternational co-ordination among the standards and practices prevailingm different countnes m addiuon to relating It to the practices In the fieldin tlus country.
O.S For the purpose of decidrng whether a particular requirement of thisstandard IS complied With, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off In accordance WIthIS: 2-196O§. The number of SIgnificant place retained In the rounded offvalue should be the same as that of the specified value In thrs standard.

1. SCOPE
1.1 This standard covers the requirements of the moulds used for castingcement or concrete cubes, cylinders and beams for tests of cement andconcrete, such as compressive strength test and llexural strength test.1.1 Moulds which are accessories to testing equipment such as vibrationmachine and joltmg apparatus are not coverd by this standard.
2. TYPES
2.1 The moulds shall be of following types:a) Cube moulds of 50, 100, ISO, 225 and 300 mrn,b) Cylindrical mould of ISO mm diameter and 300 mm height,c) Beam moulds of 100 x 100 x 500 mm and 150 x 150 x 700 mm,d) Bar moulds of 25 x 25 mm Size and 2~0 mm effective length, ande) Mould of 75 x 75 mm me and 150 to 300 mm length.
3. MATERIAL
3.1 Matenal for construcuon of moulds shall normally be as given inTable I. However, any other material which is non-absorbent and nonreactive with concrete and which shall retain the dimensional stability ofthe moulds may also be used.
4. DIMENSIONS AND TOLERANCES
4.1 The dimensions with tolerances of vanous types of moulds describedat 2.1 (a) to 2.1 (d) ( See FIg I to 8 ) shall be as given in Tables 1 to 5. Thedimensions of moulds described at 2.1 ( e) shall be such that It shall bepossible to cast specimens with a length of 150 to 300 mm and a cross-secnon as near as practicable to 75 x 75 mm.
Non - The allowable deviations for nominal dtmensrons shall be as laid down forcoarse class of deviation In]S 2\02·1969·,
5. CONSTRUClION
5.1 General - The construction of the moulds shall, 10 general, be inaccordance with Fig. I to g
NOTE - The figures are rlluerrauve only, but the dimensions and mmimum requirements where specified shall be bmdmg
5.1.1 The moulds shall be of metal and stout enough to preventdtstortion. These shall be constructed in such a manner as to facilitatethe removal of the moulded specimen WIthout damage and shall be SO
machined that, when they are assembled ready for use, the dimensions andInternal faces shall be accurate WIthin the specified hrmts, Internal faces ofthe moulds shall be smooth.
·Allowable devrancns for dimensions Without specified tolerances (first revISIon).

Cubemoulds of size 100 mm, 150 mm, 225 mm and 300 mm shall be made10 such a manner as to facihtate their separation into two parts. Cubemoulds shall be provided with a base plate.
NOTE -If required by the purchaser, cube moulds may be provided With Oat steelcovel plates to facrhtate accelerated curing of test specimens (s,t IS: 9013~1978· ).
5.2.2 Cyhndrical Mould ( see Fig. 3) - shall be made in such a manneras to facihtate separation of the mould longitudinally into two parts. Eachmould shall be provided with a base plate and a capping plate.
5.2.3 Beam Mould (see Fig. 4) - shall be made 10 such a manner as tofacilitate separation of the mould IDtO two parts. The mould shall beconstructed with the longer dimension horizontal. Each mould shall beprovided WIth a base plate
5.3.4 Bar Mould - The bar mould may be a smgle one or WIth morethan one mould compartment. Each end plate of the mould shall beequipped to hold properly 10 place a stamless steel reference point having adiameter of 6 rnrn. The reference points may be either smooth or knurledend threaded The reference pomts shall be so set that their principal axiscoincides with the pnncipal axis of the mould and shall extend 16 mm insidethe mould. Each mould shall be provided WIth a base plate Typical barmoulds are shown m FIg. 5. 6, 7 and 8.
5.3 Arrangement for Fastening/Clamping - The base plate shall preferablybe attached to the mould by cleats which may either be spring-loaded orsecured WIth threaded studs and nuts/wmg nuts The parts of the mould,
