BS 1199 and 1200:1976
Foreword This British Standard has been revised under the authority of the Aggregates, Natural Stone and Quarry Products Industry Standards Committee. The changes which have been made were occasioned by the revision of BS 812 in 1967 and BS 410 in 1969, 1969, coupled with with the metricatio metrication n programme. programme. Specific requirements relating to organic impurities have been omitted, pending a full technical revision, because of insufficient experience of applying the results from the method given in the 1967 revision revision of BS 812 and the possibility that this may be withdrawn.

Because of metrication, the size of the largest particles has been increased slightly and therefore attention may need to be given to its effects. This matter may have to be taken into account in the light of experience at the next revision of the standard. Sands appropriate for use in floor screeds screeds are specified in BS 882 and as a consequence sands for this purpose are no longer included in BS 1199. As part of BSI’s programme of metrication, this standard is expressed in metric terms. A full technical revision of these standards is under consideration. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

The method of determining the grading of sands is restricted to that of washing and decantation followed by dry sieving, and the method of dry sieving only is no longer permitted. The washing and sieving method specified is considered to be more reproducible and to produce a more realistic measure of the particle size distribution of th e sand. It also determines the clay and silt content which is now incorporated in the grading requirements. This change to washing and sieving necessitates revision of the grading limits as those previously given in this edition were based on results from dry sieving. This is not intended to lead to changes in the gradings of sand in use, but it will have the effect of bringing the majority of sands in satisfactory use within the the scope scope of BS 1199. BS 1199 now now specifies specifies two grading ranges of sand. Experience currently available suggests that satisfactory renderings can be achieved using either grade. Where there is a choice, however, the use of the coarser grade is preferred because finer sands require a higher water to cement ratio which can lead to greater shrinkage than if a coarser grading is used. Some variability in the measured properties of building sands from any source has to be expected. This is caused by sampling and testing errors in addition to the natural variability of the material itself. The application of statistical methods has been considered, but has not been included at the present time.
1 Scope This British Standard relates to nat urally occurring sands, crushed stone sands and crushed gravel sands used for external renderings and internal plastering using mixes of lime and sand (with or without the addition of cement or gypsum plaster), cement and sand (with or without the addition of lime).

NOTE 2 The most most suitabl suitable e grading grading of of sand for an external external rendering will depend, to some extent, upon the finishing treatment. The sand grading specified will, in general, be suitable for the undercoats and for some finishing coats such as the smooth (floated) finishing coats, the scraped finishes and for pebble-dash or dry-dash. For some textured finishes, such as those produced by treatment of the freshly applied final coat with a tool, it may be desirable to remove the coarser particles ( e.g. by screening through a 2 mm sieve), while for others such as “torn texture”, some proportion of material coarser than 5 mm may be needed. For roughcast (wet dashing or harling) the grading and maximum size, will vary according to the texture required and the type of aggregate: the proportion of coarse material (over 5 mm) to fine should should be about about 1 : 2.
7 Supplier’s certificate and cost of tests The supplier shall satisfy himself that the output at the source of production complies consistently with the requirements of this British Standard and, if requested, shall give a certificate to this effect to the purchaser or his representative. If the purchaser or his representative requires independent tests or the certification of individual consignments, the samples shall be taken before or immediately after delivery at the option of the purchaser or his representative, and these tests shall be carried out in accordance with the appropriate requirements of this British Standard on the written instructions of the purchaser or his representative. Unless otherwise specified with the enquiry and order, the supplier shall supply free of charge the material required for testing and the cost of the tests (unless otherwise stipulated) shall be borne: a) by the supplier, in the event of results showing that the material does not comply with the standard; b) by the purchaser, in the event of results showing that the material does so comply.

Sands for mortar for plain and reinforced brickwork, blockwalling and masonry 0 Introduction By the issue of Amendment No. 1, published May 1984, the method of determining determining the grading grading of sands is restricted to that of washing and decantation followed by dry sieving, and the method of dry sieving only is no longer permitted. The washing and sieving method specified is considered I to be more reproducible, and to produce a more Srealistic measure of the particle size distribution of Bthe sand. It also determines the clay and silt content ) c which is now incorporated in the grading ( , y requirements. This change to washing and sieving p necessitates revision of the grading limits as those o Cpreviously given in this edition were based on d results from dry sieving.
e l l Amendment No. 1 is not intended to lead to changes o r in the gradings of sand in use but it will have the t n effect of bringing the majority of sands in o c satisfactory satisfactory use within the scope of BS 1200. There n Uare advantages to be had from widening the scope in , 4 this way, provided it is recognized that the mix has 0 to be properly designed designed (see notes to Table 1) and 0 2 that for mortars made with type G sands, a higher y r cement content is generally necessary than for a mortars made with type S sands in order to achieve u r b the required strength and durability. e F With the issue of Amendment No. 1 no distinction is 0 now made between sands for general purpose 2 mortars and those for reinforced brickwork mortars, , h since for masonry designed in accordance with g u modern structural methods the same sand would be o r used for brickwork mortar, whether or not o b reinforced elements are present. Furthermore, h information available suggests that demand for g u sands conforming to Table 2 of this edition is o L neglible and Table 2 has, therefore, been deleted f o from this standard. y t i Some variability in the measured properties of s r building sands from any source has to be expected. e This is caused by sampling and testing errors in v i n addition to the natural variability of the material Uitself. The application of statistical methods has , r z been considered but has not been included at the v present time. It is anticipated that such methods c o will be included in the next full revision, by which b l r time more analytical data should be available. z v c o b l : y p o C d e 2) Full tolerances s n e c 4 i L

The mix proportions by volume of mortars made using sands complying with Table 1 of this this standard are given given in Table 6 of CP 121-1:1973. Where for a given mortar type and designation, a range of recommended sand contents is indicated in Table 6 of CP 121-1:1973, the lower sand sand volume should be used with with type G materials. Additionally, where sands are to be used in mortars for masonry designed in accordance with BS 5628-1, attention is drawn to the 28 day compressive strength requirements for mortar cubes given in Table 1 of that standard.
