Large-size crushed stone aggregate for heavy-duty infrastructure, drainage, mass concrete and specialised construction applications — supplied by OM Group across North and South Goa through its own stone-crushing operation.
No. IS 383:2016 lists 40mm and 63mm as nominal coarse-aggregate sizes. 60mm is a commercial aggregate description used within the broader 40–63mm size range, so the actual grading should be checked against sieve analysis and the project specification.
60mm is one of the largest crushed-stone grades OM Group supplies, specified where bulk, void size and economy matter more than fine placement — large mass pours, heavy drainage media and specialised foundation or fill work. OM Group produces 60mm aggregate through its own stone-crushing operation and supplies it to construction sites and project contractors across North and South Goa.
IS 383:2016, the Indian standard for aggregates in concrete, lists 63mm as its largest defined coarse-aggregate nominal size. 60mm is a trade grade that sits within this large-aggregate range — it is supplied against project and trade specification rather than as a distinct IS 383 nominal size in its own right. Confirm the exact grading requirement with your engineer or project specification before ordering.
Larger aggregate presents less surface area per unit volume than smaller grades, which is generally why large-size aggregate is specified for bulk fill, drainage media and mass-concrete work where cement economy and large void size matter more than fine placement around reinforcement.
In Indian construction trade usage, terms such as metal or blue metal are commonly used for crushed stone aggregate generally; "60mm" in trade conversation refers to this large-size grade. Terminology and exact size cut-offs vary by region and supplier, so confirm the size specification directly rather than relying on trade names alone when ordering.
Because 60mm sits above IS 383:2016's largest listed nominal size (63mm being the closest standard reference), grading and physical requirements for a 60mm supply are generally set by the specific project specification or tender document rather than a single universal table. Where a project cites a specific standard or grading envelope for large/oversize aggregate, that document governs.
Coarse aggregate at this scale is generally assessed on particle shape, cleanliness and freedom from deleterious material, water absorption, specific gravity, and mechanical performance through crushing, impact and abrasion testing, using the relevant IS 2386 methods — the same general test framework applied to OM Group's other aggregate grades.
60mm aggregate is used where the scale of the work calls for large stone — heavy foundations, mass concrete, drainage media and large-scale infrastructure fill. It is not a general substitute for 20mm or 40mm in standard reinforced concrete; suitability for any reinforced member must be verified against the project specification and applicable IS 456:2000 limits.
Large unreinforced pours where bulk and cement economy matter more than fine placement.
Large-section foundation and footing work with generous clear spacing.
Large-void drainage media and filter layers where particle size supports free water movement.
Bulk fill for large-scale infrastructure and site-development work.
Specialised construction applications where a large, angular crushed material is specified.
Sub-base and embankment fill where the project specification calls for a large graded fraction.
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, including large-size grades such as 60mm alongside its finer aggregate fractions.
OM Group operates its own transport fleet, including tippers and haulers, with operational bases at Kundaim and Thivim in North Goa and Sancoale in South Goa, coordinating aggregate dispatch within one operation rather than across separate vendors.
OM Group crushes its own aggregate from its own quarried source rock. Specification questions go to the people producing the material rather than through an intermediary.
Delivery runs on OM Group's own fleet from bases in both districts, so scheduling does not depend on a third-party transporter's availability.
60mm sits alongside other aggregate grades, GSB, boulders and ready-mix concrete. Multi-material requirements can be quoted and coordinated together.
Where current data exists for a requirement, OM Group provides it. Where it does not, OM Group says so rather than quoting a figure from a textbook.
40mm and 60mm are both large-size crushed stone grades used for mass concrete, foundations and bulk fill — the right one depends on the project specification, void size required and the scale of the work. Full specifications for the smaller of the two are on the 40mm aggregate page.
| 60mm Aggregate | 40mm Aggregate | |
|---|---|---|
| Relative particle size | Larger; lower surface area per unit volume | Smaller; higher surface area per unit volume |
| Standard reference point | Trade grade — sits above IS 383:2016's largest listed nominal size (63mm) | Standard IS 383:2016 nominal size |
| Typical applications | Heavy foundations, large-scale mass concrete, drainage media, large-fill work | Mass concrete, PCC, sub-base, foundations, large unreinforced sections |
| Reinforced concrete | Generally unsuitable for conventional reinforced members — confirm against project specification | Requires generous member dimensions and reinforcement spacing per IS 456:2000 |
| Project context | Large-scale infrastructure, heavy civil and specialised works | Foundations, mass pours, road sub-base, embankment work |
63mm is a recognised nominal coarse-aggregate size under IS 383:2016. 60mm is commercial market terminology used for large-size crushed aggregate that sits within the same general range — the two are not automatically the same product, and should not be equated without checking the actual sieve distribution against the project specification.
| 60mm Aggregate | 63mm Aggregate | |
|---|---|---|
| Status | Commercial/trade description | IS 383:2016 nominal coarse-aggregate size |
| Defined by | Project or tender specification, matched by sieve analysis | IS 383:2016 Table 2 grading limits |
| Are they the same material? | Not automatically — verify sieve distribution and the project specification before treating a 60mm supply as equivalent to a specified 63mm requirement | |
| When it matters | Where a tender or drawing explicitly calls out "63mm" as an IS 383 nominal size, confirm the supplied grading meets that clause rather than assuming a 60mm trade description is interchangeable | |
20mm and 60mm sit at opposite ends of the coarse-aggregate size range OM Group supplies — the choice is set by the member being cast and the project specification, not a general preference. Full specifications for the smaller size are on the 20mm aggregate page.
| 60mm Aggregate | 20mm Aggregate | |
|---|---|---|
| Nominal size | 60mm (trade grade) | 20mm — standard IS 383:2016 nominal size |
| Typical applications | Heavy foundations, large mass concrete, drainage media, large-fill work | RCC slabs, beams, columns, footings, RMC, specified road works |
| Reinforced concrete | Generally unsuitable for conventional reinforced members | Commonly used for conventional reinforced members |
| Placement | Needs large void space, generous clearance and section depth | Places through the reinforcement spacing found in conventional members |
| Project context | Large-scale infrastructure, heavy civil and specialised works | General building and infrastructure RCC |
Some projects specify a combination of larger aggregate sizes rather than a single grade. OM Group can discuss combined 40mm and 60mm aggregate requirements for these projects — share the required quantity, application, delivery location and project specification, and OM Group's team can confirm the appropriate supply configuration.
No fixed blend ratio is published. The split between 40mm and 60mm is set by your project's specification and mix design, not by a standard OM Group ratio — it is confirmed against the specific requirement at enquiry.
60mm aggregate is a single large-size coarse-aggregate grade; GSB (Granular Sub-Base) is a blended, graded sub-base material meeting a sieve/grading curve under MoRTH Clause 401. A 60mm fraction is not GSB on its own and cannot substitute for it without being blended to the specified curve. See the GSB page for the full specification.
Wet Mix Macadam (WMM) is a plant-mixed, moisture-conditioned base-course material under MoRTH Clause 406, produced by blending multiple smaller aggregate fractions with water to a specified grading. 60mm's large particle size sits outside WMM's typical input range. See the WMM page for what goes into the mix.
60mm aggregate is processed, crushed and screened to a large but sized fraction. Boulders are substantially larger individual stones, generally used whole rather than as a sized aggregate fraction, in applications such as pitching, gabion work and soling. They are not interchangeable products. See the Boulders page for boulder types and applications.
If your engineer or project specification has specified the aggregate size, follow that specification. Aggregate size is a design decision and nothing on this page substitutes for it.
If the requirement is still being assessed, these are the questions worth putting to your engineer:
Share the application and project details with your enquiry and OM Group can discuss the material requirement and quantities with you.
60mm aggregate rate depends on quantity, delivery location, transport distance, project specification and current supply conditions, so OM Group does not publish a fixed list price. Share your requirement for current pricing.
Rate depends on quantity, delivery location and schedule, so OM Group quotes against the specific requirement rather than publishing a list rate. Include the following:
| Product | 60mm Aggregate — plus any other grades or materials needed on the same project |
| Quantity | Volume or weight required |
| Unit | Cubic metres, tonnes or number of trips |
| Project location | Delivery destination in Goa — determines logistics and affects rate |
| Application | Mass concrete, foundation, drainage, infrastructure fill, or other |
| Delivery timeline | One-time supply or a phased schedule |
| Specification requirement | Any grading information or documentation your engineer or client requires |
| Contact | Company name and the person handling procurement |
Phased quantities are quoted and dispatched differently from a single load — flag the schedule upfront to avoid requoting later. Multiple materials can go on one enquiry. If quantity is not yet fixed, share the application and approximate scope and OM Group can work from that.

60mm aggregate is a large-size crushed stone grade used for heavy-duty foundation, drainage, mass-fill and specialised construction work. It sits within IS 383:2016's large-aggregate range, above its 40mm nominal size and close to its largest listed nominal size of 63mm.
Not exactly — IS 383:2016 lists 63mm as its largest defined coarse-aggregate nominal size. 60mm is supplied as a trade grade within this large-aggregate range, matched to the applicable project or tender specification rather than one universal standard table.
60mm aggregate is used in heavy foundations, large-scale mass concrete, drainage works, infrastructure fill and specialised large-scale construction applications.
Generally not for conventional reinforced members — its size is unsuitable for typical reinforcement spacing. Suitability must be verified against the project specification and IS 456:2000 aggregate-size limits before use in any reinforced element.
Both are large-size grades used for mass concrete and bulk fill. 40mm is a standard IS 383:2016 nominal size commonly used in mass concrete, PCC and sub-base work; 60mm is a larger trade grade used where even greater bulk, void size or scale is required. See the full 40mm aggregate page.
Large-size crushed aggregate such as 60mm is commonly used in drainage media and filter layers where a large void size supports free water movement, subject to the project's specification.

63mm is a recognised nominal coarse-aggregate size under IS 383:2016. 60mm is a commercial market description used for large-size aggregate within that same general range. The two are related but not automatically identical — check the sieve distribution against your project specification.
Not automatically. 63mm is IS 383:2016's defined nominal size; 60mm is commercial terminology for large aggregate in that range. Where a tender specifically calls for 63mm, confirm the supplied grading meets that clause rather than assuming a 60mm trade description is interchangeable.
They sit at opposite ends of the coarse-aggregate range. 20mm is a standard IS 383:2016 nominal size used in conventional reinforced concrete. 60mm is a large trade grade generally unsuitable for reinforced members, used instead for heavy foundations, mass concrete and drainage media.
A combined supply of 40mm and 60mm aggregate for projects whose specification calls for both larger sizes on the same requirement. OM Group can supply this as a project-specific combination — there is no fixed blend ratio; the split is set by your project specification.
60mm aggregate is a single large-size coarse-aggregate grade; GSB (Granular Sub-Base) is a blended, graded sub-base material meeting a sieve curve under MoRTH Clause 401. A 60mm fraction is not GSB on its own.
Wet Mix Macadam (WMM) is a plant-mixed, moisture-conditioned base-course material under MoRTH Clause 406, blended from smaller aggregate fractions. 60mm's large particle size sits outside WMM's typical input range and is a distinct product.
60mm aggregate is processed, crushed and screened to a large but sized fraction. Boulders are substantially larger individual stones, generally used whole in applications such as pitching, gabion work and soling.
Share quantity, project location and timeline, and OM Group will confirm current availability and pricing for the requirement. Multiple materials, including a combined 40mm/60mm requirement, can be quoted together.
