(CED 4) Reprography Unit, BIS, New Delhi, India 2 IS : 4098 · 1983 Indian Standard SPECIFICATION FOR LIME-POZZOLANA MIXTURE ( First Revision) o. FOR E W 0 R D 0.1 This Indian Standard ( First Revision) was adopted by the Indian Standards Institution on 28 October 1983, after the draft finalized by the Building Limes Sectional Committee had been approved by the Civil Engineering Division Council. 0.2 Lime-pozzolana mixture which is essentially a mixture of lime and pozzolana could be used as an alternate cementing material to ordinary Portland cement for certain categories of work like masonry mortar and plaster, foundation concrete, levelling coarse under floors, road and airfield bases, precast building blocks (including light weight blocks), paving blocks, soil stabilization and as filler in water bound macadam in road construction. Hence the production and marketing of properly mixed, ready to use and properly packaged dry mixtures of Iirne-pozzolana of specified strength would go a long way in making available a standardised product that could be safely used in construction as a substitute for Portland cement in places mentioned above. 0.3 Lime pozzolana mixtures are normally manufactured by intergrinding the ingredients in a mill or by blending in the form of powder. The hardening of lime pozzolana mixture depends upon the lime reactivity of the pozzolana and in general is slower than that of cement, but is satisfactory for most of the normal uses. Higher the lime reactivity of pozzolana, quicker win be the rate of setting and hardening of the lime pozzolana mixture. Where improved early strength is required, the rate of hardening can be accelerated by adding gypsum. This is done by intergrinding in the manufacturing stage in the mill or by blending the mixture and the gypsum in the form of powder of required fineness, adopting suitable measures to ensure a uniform mixture. This standard has been prepared with a view to lay guidance in respect of production and use of lime-pozzolana mixture and to lay down its requirements to ensure the availability of such mixtures in standardized form. 3 IS 14098· 198' 0.4: This standard, first published in 1967, was intended to bring out a long felt uniformity in the variety of practices being followed towards manufacture and use of this product. This revision has been prepared with a view to incorporate improvements found necessary in the light of usage of the standard. In this revision, the methods of tests to assess the qualitative requirements have been removed and reference has been drawn to those Indian Standards in which these methods are covered. Reference has also been drawn of latest Indian Standards and attempt has been made to make the standard performance based. Additional chemical requirements have been included in order to ensure meaningful control over the mixture. 0.5 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in a accordance with IS : 2·1960·. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. I. SCOPE 1.1 This standard covers the requirements of Iime-pozzolana mixture for use in construction wo-ks, 2. TERMINOLOGY 2.0 For the purpose of this standard the following definition in addition to those given in IS : 6508-1972f and IS : 4305-1972: shall apply· 2.1 Po··oIaDa - An essentially silicious material which while in itself possessing no cementitious properties will, in finely divided form and in the presence of water, react with calcium hydroxide at ordinary temperature to form compounds possessing cementitious properties. 3.

PROCEDURE FOR SAMPLING 8-3.1. Lime pozzolana mixture samples shall be taken by anyone of the methods specified in B-3.1.1 to B-3.1.3. 8-3.1.1 Sampling Small Qpantities - Each sample for testing shall consist of a mixture of approximately equal proportions selected from at least 12 different bags or other packages when the mixture is not loose. When 8 IS I 4098 - 1983 the number of bags or packages is less than 12, portions shall be selected from each bag or package. Every care shall be taken during the selection to obtain a fair average sample. The final sample shall weigh at least 5 kg.

In each case the samples collected by small increments shall be rapidly mixed in a place free from draught, and thereafter stored in air-tight container of 7 kg capacity. In case of dispute, at least two such containers shall be filled, one sent to an approved laboratory and the other kept as a reference sample by the supplier. 8-3.1.2.1 From Conveyor Delivering to Bulk Storage or Discharging from Bulk Storage - One sample of not less than 2-5 kg shall be taken from each 15 bags or 50 tonnes or parts thereof passing over the conveyor, or from discharge openings of bulk storage by taking small samples at regular intervals, either by scoops or by automatic samplers. 8-3.1.2.2 From Bulk storage by Means of Proper Sampling Tubes - When the method described in B-3.1.2.1 cannot be applied, and when thedepth of mixture to be sampled does not exceed 3 m, samples may be obtained by suitable tubes inserted vertically to the full depth of the mixture. Samples so taken shall be obtained from points well distributed over the area of storage. 8-3.1.3 In all other cases, samples shall be taken from each 50 bags or portion thereof in the lot and mixed to form test samples, In the case of samples from trucks where the mixture is being trucked from one mill, it is permissible to combine the samples from several trucks to form a test sample each representing not more than 1 000 bags. 8·4.
