IS 383 (1970): Specification for Coarse and Fine Aggregates

Sep 25, 1970 · 0.31 The four grading zones indicated in this standard are meant to cover the use of the natural sands available in the country. It is, however, necessary to appreciate the limitations in either using a very coarse sand or a very fine sand and the need to make suitable changes in the mix design.

Grading of Aggregate and Fineness Modulus of grading of

Grading of aggregate is the particle size distribution, which is determined by sieve analysis. The particle size distribution of a mass should be such that, voids between the coarse aggregate should be filled by fine aggregates. The grading of the aggregate affects the workability of concrete. When grading of aggregate is done by sieve analysis.

Grading of Sand: The particle size grading of sand for plaster work for internal as well as external walls and ceiling as analyzed by the method described in IS 2386(Part 1): 1973 shall be as specified in Table 1. Where the grading falls outside the limits of the grading zones of sieves other than 150, 300 and 600 micron IS Sieve by a total ...

Sieve analysis of sand and its Grading Zone - Engineering

What Is Fineness Modulus of Sand? Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness

Practical Grading of Aggregates | Concrete Technology

Zone II represents medium sand, generally suitable for the standard 1:2 fine to coarse mix, when the maximum size of coarse aggregate is 20 mm. The choice of correct proportion is particularly important as the grading of the sand approaches the fine outer limit of zone 4 or the coarse outer limit of zone I.

BIS Specifications for m Sand - Parts2build.com

Generally, Sand is classified as Zone I, Zone II, Zone III and Zone IV (i.e. Coarser to Finer). There is sieve designation for each zone. Gradation is made in accord with the usage of the sand. There are testing sieves, consists of 4.75mm, 2.36mm, 1.183mm, 600microns, 300 microns, 150 microns and a pan

Once the grading determination has been made, the classificatio can be further refined by estimating the percentage of the sand size particles present in the sample. If the gravel is : dirty: then it will be important to determine whether the fines are either

IDENTIFYING ZONE 0, ZONE 1, AND ZONE 2 HAZARDOUS AREAS

Zone 0. Zone 0 is an area in which an explosive atmosphere is present continuously for long periods of time or will frequently occur. Zone 1. Zone 1 is an area in which an explosive atmosphere is likely to occur occasionally in normal operation. It may exist because of repair, maintenance operations, or leakage. Zone 2
