( Second Revision)

o. FOR E WORD

0.1 This Indian Standard (Second Revision )was adopted by the Bureau of Indian Standardson 3 October 1988, after the draft finaHzed bythe Cement and Concrete Sectional- Committeehad been approved by the Civil EngineeringDivision Council.

0.2 Masonry cement is obtained by intimatelygrinding a mixture. of Portland cement clinkerand gypsum with pozzolanic or inert materials,and air entraining plasticizer in suitable propor­tions, generally to a fineness greater than that ofordinary Portland cement. Masonry cement ischiefly intended for use in masonry mortars forbrick, stone and concrete block masonry, and forrendering and plastering work. Because of itsproperty of producing a smooth, plastic, cohe­sive and strong; yet workable, mortar whenmixed with fine aggregates, masonry cement isconsidered superior to lime mortar, lime-cementmortar or cement mortar. Lime mortars arerelatively weaker in strength and slower settingand they sometimes bleed under pressure.Ordinary cement mortars, although rast settingand capable of high strength development, areharsh, non-plastic and non-cohesive with theresult that they cannot take up the shrinkage andtemperature mo'tementl in the masonry and areliable to result in comparatively wide crackspassing right through the bricks or buildingblocks al compared to a number of evenlydistributed hair crack. in the joints which occurwhen weaker mortars containing lime are used.Properly proportioned and gauged lime-cementmortars can be' made to possess the desiredpropertiel of a good ma,onry mortar but thepreparation of lime-cement mortars is timeconsuming and also unslaked lime and magnesia,when present in such mortars, can cause delayedespanaioD and consequently defects in themasonry and. plaster work. In order to avoidthe nece.sity for mixing cement and lime, and Inorder to minimize the ri.k of trouble from expan­sion due to 'the presence of small quantitiel of

1.1 This' ltandard lays down the requirementifor 'masonry cement to be used for aU generalpUIp)I. where mort.n· for masonry arerequired.

unslaked lime, the use of masonry cement isquite popular in a number of countries abroadand itl use should be encouraged in this countryalso. The use of masonry cement will not onlyimprove the quality of masonry mortars but willalso meet the emergent need to increase theproduction of cement by better utilization ofavailable resources in . the country. Masonrycement is. however, not intended (or use instructural ~oncrete, for flooring and foundationwork or for reinforced and prestressed concreteworks.

0.3 This standard was first issued as an emer­gency standard in 1966 to meet the immediateneeds or the building industry and subsequentlyrevised in 1967. In the present revision, require­ments regarding air content and. water retentionhave been lowered, retest has been allowed incase of Le-Ohatelier and autoclave soundness. test,and a clause on false let of cement has beenincorporated in addition to SOl!1e other minormodifications.

O.~ Mass of cement packed in bags and thetolerance requirement! for the mass or cementpacked in ba,s shall be in accordance with therelevant provllioDS of the SttJ"d.,ds of WIi,htrand M,asuru (Paekag,d C6m""diti,s·") Rutu, 1977and 'A-l.2 (", Appendix.A). Any modifi­e;atioQ in these rule. in respect of tolerance onmass of cement would apply automaticaUy tothis atandard.

0.5 For the purpose of deciding whether aparticular requirement of this standard. is com­plied-with, the final value, observed or calculated,expressing the result of a test or analysis, shallbe rounded. off in accordance with IS: 2-1960*.The number or lignificant places retained in therounded off value should be the same al that ofthe specified value in this standard.

4.1 This requirement shall apply only when a2.2 Portla.d CelDeat CliDker - Portland purchaser specifically states that cement shall becement clinker conforming to the requirements non-staining to limestone.

3.1 Masonry cement, when tested in accordancewith the methods of test specified in IS : '4031­1988t, shall conform to the physical require­ments given in Table 1.

3.1.1 Ifcement exhibit. false set, the ratio of finalpenetration measured after 5 minutes of comple­tion of mixing period to the initial penetrationmeasured exactly after 20 seconds of completionof mixing period, expressed as percent, shall benot le'l than 50. In the event of cement exhibit­ing false set, the initial and final setting time ofcement when tested by the method described inIS :; 4031·1~88t after breaking the raise set, shallc~Dfb.m tOIthe requirements given in Table I.
