What Is 12mm Aggregate?
📖 DEFINITION
12mm aggregate is crushed stone screened to a nominal size of 12mm, used mainly as the coarse aggregate in concrete. In Chennai it goes by three names that mean the same thing: aggregate, jelly and blue metal. “Jelly” is the common site term for crushed stone, and “blue metal” refers to the bluish crushed granite widely used across Tamil Nadu. They are not different products and they are not priced differently here.
This matters when you are comparing quotes. A supplier quoting “12mm jelly” and another quoting “12mm blue metal” are quoting the same material, so any difference between them is a difference in price, grading or transport — not in what arrives at your site.

| Unit of sale | Listed rate | What it means |
|---|---|---|
| Per CFT (cubic foot) | ₹48 | You are buying volume. Moisture in the load does not change what you pay. |
| Per ton | ₹1,173 | You are buying weight. Water in a wet load is part of that weight. |
| Per load | Quoted on request | A load is a vehicle, not a fixed quantity. What it costs depends on vehicle capacity, the actual quantity carried, transportation and delivery location. |

CFT, Ton or Load: Which Unit Should You Buy In?
Most buyers assume one unit must work out cheaper. At our listed rates, it does not — and the reason is worth understanding, because it tells you which unit protects you.
| Quantity | Cost at ₹48 / CFT | Same quantity in tons | Cost at ₹1,173 / ton |
|---|---|---|---|
| 100 CFT | ₹4,800 | ≈ 4.09 tons | ₹4,800 |
| 250 CFT | ₹12,000 | ≈ 10.23 tons | ₹12,000 |
| 500 CFT | ₹24,000 | ≈ 20.46 tons | ₹24,000 |
| 1,000 CFT | ₹48,000 | ≈ 40.92 tons | ₹48,000 |
The two listed rates are consistent with each other at roughly 24.4 CFT per ton. Buy 1,000 CFT by volume or the same material by weight and the arithmetic lands on ₹48,000 either way. (These totals are simple arithmetic on the listed rates and exclude transportation, unloading and applicable taxes.)
WEIGHT AND VOLUME DO NOT MOVE TOGETHER
That 24.4 CFT per ton is a pricing relationship, not a guaranteed physical conversion. What a real lorry-load actually weighs for a given volume shifts with moisture, grading and how the material has settled. And that is where the two units stop being equivalent. Buy by weight and water in a wet load is part of what you pay for — rain-soaked aggregate weighs more and builds no more. Buy by volume and moisture is not your problem, because you are paying for the cubic feet that arrive. After heavy rain, or when material has been stockpiled uncovered, that difference is real money on a large order.
Where 12mm Aggregate Is Used
12mm is one of several coarse aggregate sizes, and it earns its place where larger stone would not fit or flow properly:
Concrete in thinner sections
Where a larger aggregate would not pass cleanly between faces of the formwork.
Closely spaced reinforcement
Where stone needs to travel between bars without jamming.
Blending with other sizes
To achieve a specified grading, rather than being used alone.
Paving and flooring beds
And similar work where a finer coarse aggregate gives a tighter finish.
12mm IS NOT A DEFAULT SIZE
Aggregate size is part of the structural design. It is selected against member thickness, reinforcement spacing and concrete cover, and the engineer who prepared your drawings will have specified it. Substituting a different size because it is cheaper or more readily available is a design change, not a purchasing decision — ask before you order. If your drawings do not state a size, that is a question for your engineer rather than for your supplier.
How to Judge Quality Before You Accept a Load
You do not need a laboratory to catch the obvious problems. Four checks take a minute at the tipping point:
Dust and fines
Pick up a handful and release it. Heavily coated stone leaves your palm grey and dusty, and that coating sits between the stone and the cement paste.
Soil and organic matter
Clods of earth, roots or leaves mean the material has been handled or stored carelessly.
Shape
Angular pieces pack and interlock well. A load with many thin, flat or elongated pieces packs poorly and works harder to place.
Size consistency
A 12mm load should look like 12mm throughout, not a mix with noticeably larger or smaller stone through it.

What Affects Aggregate Prices in Chennai
Quarry output
Crushing and screening costs at source.
Order quantity
Bulk requirements are quoted differently from small orders.
Material quality and grading
And how consistent that grading is load to load.
Diesel and distance
Transportation to your site is often the largest variable.
Site accessibility
A narrow approach or restricted unloading changes the vehicle that can be used.
Seasonal demand
And general market conditions.
Two sites buying identical material on the same day can land on different totals, and the difference is usually transport rather than the stone.

How to Buy 12mm Aggregate: Step by Step
Estimate your quantity
Work from your concrete volume and mix proportions with your engineer or contractor, and settle on a single unit — CFT or tons — before you ask anyone for a price.
Compare on the same unit
A quote per CFT and a quote per ton cannot be compared by eye. Convert both to the same unit first, and check what each quote includes.
Confirm the size against your drawings
Make sure 12mm is what the design calls for before ordering, not simply what is available.
Confirm transportation separately
Ask whether the quoted rate includes delivery to your address, and what unloading involves.
Arrange delivery around site access
Tell the supplier about narrow roads, low cables, gate widths or restricted hours before the vehicle is loaded, not after it arrives.
Inspect on arrival, before tipping
Run the four checks above while the material is still on the vehicle. Once a load is tipped and mixed into your stockpile, it is nobody’s to return.
BULK OR PHASED DELIVERY?
For bulk quantities, phased deliveries or anything that needs scheduling around site access, contact Buildiyo.Store with your quantity and site address and our team will confirm what can be supplied and when.

Three Names, One Material, One Rate
Jelly, blue metal, aggregate — the same crushed stone. So when two quotes differ, the difference is price, grading or transport, never the product. Compare on one unit and you can see which.
