6mm crushed stone aggregate for paver blocks, tiles, precast products and surface finishes — supplied by OM Group across North and South Goa through its own stone-crushing operation.
6mm aggregate is the smaller crushed stone fraction used where surface finish, compaction and product consistency matter — paver blocks, concrete tiles, blocks, precast products and finishing work. It is a manufacturing and finishing material rather than a structural concrete aggregate. OM Group produces 6mm aggregate through its own stone-crushing operation and supplies it across North and South Goa to paver and block manufacturers, precast units, finishing contractors and builders.
Aggregate is the stone fraction of concrete and mortar. In standard aggregate classification, the 4.75mm sieve is the boundary between fine aggregate, such as sand, and coarse aggregate. 6mm crushed aggregate is generally treated as a coarse aggregate fraction because it sits above that boundary, though the actual grading should be confirmed against the product requirement.
6mm is one of the smaller crushed stone fractions traded in construction markets. Because the particles are small, it packs closely, fills voids efficiently and produces an even surface — the properties a paver block, a chequered tile or a rendered finish depends on. Those are different properties from the ones structural concrete needs, which is why 6mm is a finishing and manufacturing material rather than an RCC aggregate.
Where 6mm sits against the standard. IS 383:2016 tabulates nominal coarse aggregate sizes of 10, 12.5, 16, 20, 40 and 63mm. 6mm is not one of them. A 6mm product should therefore be specified by its actual grading and sieve requirements rather than presented as an IS 383 nominal-size grade. If your production or client requires a particular sieve range, state it with your enquiry.
Trade names for smaller crushed stone fractions vary considerably across India, and 6mm sits close to the dividing line between several of them.
Widespread, particularly in eastern and southern India.
Commonly used for material below roughly 6mm.
Gujarat and western India, commonly used for material above roughly 6mm.
Appears in some western India trade usage specifically for 6mm.
Southern terms for crushed stone generally.
These are not exact synonyms. Usage varies by region, supplier and application — particularly between asphalt road work and cement concrete work.
6mm is not the conventional coarse aggregate size for structural RCC. Structural concrete commonly uses 10mm, 20mm and other project-specified aggregate sizes.
A major application for 6mm aggregate. Aggregate selection is part of the approved paver mix and material requirements — 6mm may form part of a mix where the approved formulation calls for it.
Surface appearance depends heavily on the smaller aggregate fraction, particularly on exposed or polished faces.
The finer fraction assists mould fill and produces a closer finish on exposed faces.
Used in detailed and exposed-face elements where the approved mix calls for a smaller fraction.
Used where a specified crushed fraction is required in rendered or textured finishes. Conventional plaster uses sand; confirm what the specification calls for.
Tile bedding and floor screeds; roof chippings over waterproofing membranes; decorative and landscaping work; drainage and filter media; fine asphalt layers — all conditional on the membrane system, specification and fines content.
These three are confused regularly, and ordering the wrong one is an expensive mistake for block and paver producers.
| Material | What it is |
|---|---|
| 6mm aggregate | A coarser crushed stone fraction at 6mm trade size |
| Stone dust / crusher dust | The fine by-product fraction from crushing, with a higher proportion of fines |
| M-Sand | Manufactured sand — crushed rock processed and graded to sand requirements, with fines controlled |
The practical difference is fines content and the degree of grading control. Most paver, tile and block mixes use a combination rather than one material alone, in proportions set by the mix design. If a mix design exists, order to it. If you are still working out which fractions your product needs, share what you are manufacturing with your enquiry and OM Group can discuss the material requirement.
| 6mm Aggregate | 10mm Aggregate | |
|---|---|---|
| Size | 6mm trade size | 10mm nominal size |
| Standards position | Not among the nominal coarse aggregate sizes listed in IS 383:2016 | Listed nominal size in IS 383:2016 |
| Primary role | Finishing and manufacturing input | Coarse aggregate for thin and detailed structural sections |
| Typical applications | Paver blocks, tiles, blocks, precast, surface finishes, screeds, decorative work | RCC with congested reinforcement, thin sections, precast, blended grading with 20mm |
| Structural RCC | Not the conventional size | Used where placement or finish is the constraint |
| Surface finish | Close, even finish; suits exposed and pressed faces | Finer than 20mm; used where finish matters in structural work |
| Common buyer | Paver, tile and block manufacturers; finishing contractors | RCC contractors, precast manufacturers, RMC plants |
Where a product needs both a finishing fraction and a structural coarse fraction, both can be discussed on the same enquiry. For the full 10mm versus 20mm structural comparison, see the 10mm aggregate page.
Aggregate buyers order in different units depending on local trade practice and project documentation. In Goa and Maharashtra, brass and trips are common, while specifications and quotations often run in cubic metres or tonnes.
| Unit | Approximate equivalent |
|---|---|
| 1 brass | 100 cubic feet ≈ 2.83 m³ |
| 1 m³ of 6mm aggregate | ≈ 1.6 tonnes |
| 1 brass of 6mm aggregate | ≈ 4.5 tonnes |
| 1 tonne of 6mm aggregate | ≈ 0.63 m³ |
| 1 cubic foot (CFT) of 6mm aggregate | ≈ 45 kg |
If you know your requirement in one unit only, send it in that unit. OM Group can work from brass, cubic metres, tonnes or number of trips.
OM Group operates a vertical shaft impactor (VSI) stone-crushing facility at Banda Wafoli, producing multi-grade crushed stone aggregate from in-house quarried source rock. VSI crushing accelerates stone against stone rather than compressing it, and is generally associated with a more cubical particle shape than compression crushing.
OM Group operates its own transport fleet, including tippers, haulers and transit mixers, with operational bases at Kundaim and Thivim in North Goa and Sancoale in South Goa. Where 6mm is a recurring manufacturing requirement, scheduled supply can be discussed against the production programme rather than arranged order by order. Share your weekly or monthly requirement with your enquiry.
OM Group crushes its own aggregate from its own quarried source rock. Questions about grading and consistency go to the people producing the material.
For paver, tile and block producers, changes in grading and fines can affect the finished product. Material from a single crushing operation removes the variation that comes from switching between traders and sources.
Where the requirement is recurring, dispatch can be planned around the production schedule rather than handled order by order, using OM Group's own fleet from bases in both districts.
OM Group can discuss 6mm alongside 10mm, 20mm and other construction materials on the same enquiry.
Rate depends on quantity, delivery location and supply frequency, so OM Group quotes against the specific requirement rather than publishing a list rate. Include the following:
| Product | 6mm Aggregate — plus any other grades or materials needed |
| Quantity | Volume or weight required |
| Unit | Brass, cubic metres, tonnes or number of trips — whichever you work in |
| Delivery location | Plant or site in Goa — determines logistics and affects rate |
| What you are producing | Paver blocks, tiles, blocks, precast, screed, finishing work, or other |
| Supply frequency | One-time delivery, or a recurring weekly or monthly requirement |
| Grading requirement | Any specific sieve range your product or client requires |
| Contact | Company name and the person handling procurement |
Recurring requirements — share the production programme rather than a single figure, so scheduling and rate can be discussed together. Multiple fractions can go on one enquiry. Matching an existing product — if you are changing supplier and need the finishing fraction to match what you currently use, say so, and bring the grading you work to if you have it.

Because 6mm is not one of the nominal coarse aggregate sizes IS 383:2016 tabulates, a nominal-size conformity claim would not be meaningful for this product. It is properly specified by its actual grading and sieve requirements. State what your production or client requires with your enquiry — a sieve range, grading information, or documentation for records — and OM Group will confirm what is currently available. Where a requirement calls for documentation that is not currently held, OM Group will say so directly rather than supplying a generic substitute.
6mm aggregate is crushed stone at a 6mm trade size, used mainly in paver block and tile manufacture, blocks, precast products and surface finishes. It is a finishing and manufacturing material rather than a structural concrete aggregate.
6mm crushed aggregate is generally treated as a coarse aggregate fraction because it sits above the 4.75mm sieve, which is the boundary between fine and coarse aggregate in standard classification. Actual grading should be confirmed against the product requirement.
IS 383:2016 tabulates nominal coarse aggregate sizes of 10, 12.5, 16, 20, 40 and 63mm, and 6mm is not among them. A 6mm product should be specified by its actual grading and sieve requirements rather than presented as an IS 383 nominal-size grade.
6mm aggregate is used mainly for paver blocks, concrete and chequered tiles, hollow and solid blocks, precast products and surface finishing. It is also used, where specified, in screeds and tile bedding, roof chippings over waterproofing, decorative and landscaping work, drainage media and fine asphalt layers.
6mm is not the conventional coarse aggregate size for structural RCC. Structural concrete commonly uses 10mm, 20mm and other project-specified sizes, with the choice set by the member and the approved mix design.
Yes, this is a major application. Concrete paving block production is governed by its product specification, and aggregate selection forms part of the approved mix and material requirements — 6mm may be included where the approved formulation calls for it.
6mm can be used where a specified crushed fraction is called for in grit or textured finishes. Conventional plaster uses sand, so confirm what the specification requires.
6mm is a finishing and manufacturing material for pavers, tiles, blocks, precast and surface work. 10mm is a coarse aggregate used in structural concrete where sections are thin or reinforcement is congested. They serve different purposes and are not substitutes.
6mm aggregate is a coarser crushed stone fraction at 6mm trade size. Stone dust is the fine by-product fraction from crushing, with a higher proportion of fines. They behave differently in a mix and are not interchangeable.
6mm aggregate is a coarser crushed stone fraction. M-Sand is manufactured sand — crushed rock processed and graded to sand requirements with fines controlled. Most block and paver mixes use a combination, in proportions set by the mix design.
Depending on region and supplier it may be called stone chips, grit, kapchi or mamri. These are not exact synonyms and usage varies, so confirm the sieve size when ordering rather than relying on the trade name.
1 brass is 100 cubic feet, approximately 2.83 m³. At a typical bulk density of around 1,600 kg/m³, 1 brass of 6mm aggregate is approximately 4.5 tonnes. This is an industry estimate — actual weight varies with grading, moisture, particle shape and source.
Approximately 1.6 tonnes, based on a typical industry bulk density of around 1,600 kg/m³. Use confirmed documentation for billing and mix design.
Yes. OM Group can work from brass, cubic metres, tonnes or number of trips. Send the requirement in whichever unit you work in.
