Overview of Aggregate Testing (Sand & Coarse Aggregate)

Tested by: NABL-accredited partner lab
Regulation: IS 383 & IS 2386
Typical turnaround: 5–7 working days
Sample needed: 25–50 kg per source

Aggregates make up most of the volume of concrete, so their quality decides its strength, workability and durability. IS 383 specifies aggregates for concrete, including manufactured sand, and the IS 2386 series sets the test methods: grading, particle shape, strength, specific gravity, water absorption, soundness and deleterious materials.

With river sand scarce in many states, manufactured sand (M-sand) from crushed stone is now widely used; its grading and fines content need checking because they affect water demand. Road and railway projects add tests such as Los Angeles abrasion and aggregate impact value. Quarry owners test to qualify their sources for government and infrastructure work.

How we handle Aggregate Testing (Sand & Coarse Aggregate)

1
Assessment of requirement
We confirm the standard, the list of tests and how many samples your product needs.
2
Sample collection
We collect the samples from your factory or warehouse, or tell you exactly where to send them.
3
Right lab assigned
We choose an accredited lab (NABL, BIS-recognised or ILAC) that covers your standard and can start soonest.
4
Testing
The lab tests your samples against the standard. We follow up and tell you at once if a test fails.
5
Test report
You receive the signed test report, ready to use for BIS, WPC, CE or your buyer.

What the lab tests

Parameter	Why it is checked
Sieve analysis and grading zone	Fine and coarse aggregate grading
Silt, clay and fine dust content	Water demand and bond
Flakiness and elongation index	Particle shape
Crushing, impact and abrasion value	Strength and wear resistance
Specific gravity and water absorption	Mix design inputs
Soundness and alkali-aggregate reactivity	Long-term durability

The final list depends on your product, its standard and the purpose of testing. We confirm it with you before the sample goes to the lab.

Frequently asked questions

Is M-sand as good as river sand?

Well-graded M-sand from good rock performs well in concrete and is permitted by IS 383. Testing grading, fines and particle shape for each source shows whether it suits your mix.

Which standard is the product tested against?

The Indian Standard, international standard or buyer specification that applies to your product and market. We confirm it with you before testing, and the report states the method used for each parameter.

Who carries out the testing?

Instacertify’s partner laboratories, accredited by NABL to ISO/IEC 17025 for the parameters on your report. We choose the lab, arrange the sample, follow up until the report is issued and explain the results to you.
