The Bureau of Indian Standards specifies requirements for coarse and fine aggregates used in concrete under IS 383:2016 – Coarse and Fine Aggregate for Concrete – Specification (Third Revision).
IS 383:2016 covers different types of fine aggregate, including natural sand, crushed sand, mixed sand and manufactured fine aggregates. The suitability of sand for concrete depends on its grading, particle characteristics, source and compliance with the applicable project requirements.
If your concrete mix also requires coarse aggregate, view our Jelly Stone for Construction in Bangalore page for available sizes, indicative pricing and delivery information.

Grading of Fine Aggregate
Fine aggregate is classified into Grading Zones I, II, III and IV according to the percentage of material passing through standard IS sieves. Zone I represents relatively coarser material, while Zone IV represents relatively finer material.
Zone II grading is commonly used for many concrete applications. However, the appropriate grading should always be selected according to the concrete mix design, structural requirements and applicable project specifications.
Typical Zone II Grading Requirements under IS 383:2016
| IS Sieve Size | Zone II – Percentage Passing |
|---|---|
| 10 mm | 100% |
| 4.75 mm | 90–100% |
| 2.36 mm | 75–100% |
| 1.18 mm | 55–90% |
| 600 micron | 35–59% |
| 300 micron | 8–30% |
| 150 micron | 0–10% |
IS 383:2016 also contains specific provisions that depend on the type and source of fine aggregate. Manufactured or crushed stone sand may therefore have additional requirements relating to very fine material, including material passing the 150 micron sieve.
Why Sieve Analysis Matters
Sieve analysis is used to determine the particle-size distribution of sand. Proper grading is important because it can influence concrete workability, water demand, cement requirement and the overall performance of the concrete mix.
A properly graded fine aggregate contains particles of different sizes in suitable proportions. This helps reduce excessive voids within the mix and can contribute to more consistent concrete performance.
Other Quality Requirements
Grading is only one aspect of aggregate quality. IS 383:2016 also addresses requirements relating to characteristics such as deleterious materials, particle shape and texture, water absorption, soundness and alkali–aggregate reactivity.
Relevant aggregate testing methods are covered under the IS 2386 series. Testing requirements should be selected according to the material, project specification and applicable engineering requirements.
Choosing M Sand for Construction
When selecting M Sand or another fine aggregate for concrete, the material should be assessed against the applicable project specification and relevant BIS requirements. The required grading zone can vary depending on concrete mix design, intended application and engineering requirements.
Where required, buyers should request relevant test reports or material specifications from the supplier and confirm that the selected material is appropriate for the intended construction application.

M Sand and Coarse Aggregate Requirements
Concrete generally requires both fine aggregate and coarse aggregate in proportions determined by the approved concrete mix design. M Sand may serve as the fine aggregate where suitable, while Jelly Stone or other graded coarse aggregate may be selected according to the structural requirement.
