7 FOREWORD This Indian Standard ( First Revision ) was adopted by the Indian Standards Institution on 30 September 1980, after the draft finalized by the Building Construction Practices Sectional Committee had been approved by the Civil Engineering Division Council. This standard was first published in 1965. The revision has been prepared in the light of experience gained in the use of the standard during course of these years.: A number of modifications in the provisions of the standard have been made, important among which is the particle size grading of sand for masonry work. The grading has been made more practicable by specifying only one limit of grading for both reinforced and unreinforced masonry work. The performance of masonry mortars is characterised by properties like strength, volume change, water retentivity, workability, etc.

8 The role of sand in the mortar is to obtain these properties in the mortar to the best extent as would be possible with the amount of binder materials, such as cement, lime, etc, that are used in the mortar. It is not widely apprecia- ted that sand for use in masonry mortar has got certain essential require- ments to satisfy, namely, freedom from detrimental impurities and particle size distribution within specific limits of grading. Quite often sand is specified naming the localities from which it should be procured and probably it is the experience in many places that sands so available give satisfactory performance in normal construction work. While it would not be practicable often to change existing practice completely, there is room for improvement in the light of research and some of the basic require- ments for sand to serve as an ingredient in masonry mortar can be specified, by choosing, if need be, better sources of supply and also by proper blending of sands from different sources.

9 This standard specifies the basic requirements for sand for use in masonry mortars . In the formulation of this standard, due weightage has been given to co-ordination among the standards and practices prevailing in different 3 IS t 2116 - 1980 countries in addition to relating it to the practices in this field in the country. This standard contains clause 7 which requires the supplier to furnish some technical information at the request of the purchaser. For the purpose of &ciding whether a particular requirement of this standard is complied x X1, the final value, observed or calculated, express- ing the result of a test or analysis, shall be rounded off in accordance with IS : Z-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.

10 1. SCOPE This standard covers the requirements of naturally occurring sands, crushed stone sands and crushed gravel sands used in mortars for construction of masonry .. 2. TERMINOLOGY For the purpose of this standard, the following definitions shall apply. Sand - A fine aggregate which is either natural sand or crushed stone sand or crushed gravel sand. Natural Sand - A fine aggregate produced by the natural disinte- gration of rock and which has been deposited by streams or glacial agencies. Crushed Stone Sand and Crushed Gravel Sand - A fine aggre- gate produced by crushing stone or natural gravel. 3. QUALITY OF SAND General - The sand shall consist of natural sand, crushed stone sand or crushed gravel sand or a combination of any of these.
