Overview of Cement Testing

Tested by: NABL-accredited partner lab
Regulation: IS 269, IS 1489, IS 455
Typical turnaround: 30 days for 28-day strength
Sample needed: 5 kg in an airtight bag

Cement sold in India has long been under compulsory BIS certification. Ordinary Portland cement is specified in IS 269, Portland pozzolana cement in IS 1489 and Portland slag cement in IS 455, with physical tests done to the IS 4031 series and chemical analysis to IS 4032. Manufacturers and grinding units test for their ISI licence and every dispatch, and importers need the same for their licence.

Construction projects test cement on receipt, because storage, mixing of grades and old stock affect strength. The key results are fineness, consistency, setting time, soundness and compressive strength at 3, 7 and 28 days. Cement results then feed into concrete testing and mix design.

How we handle Cement Testing

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
Fineness (Blaine)	Rate of strength gain
Standard consistency and setting time	Initial and final setting
Soundness (Le Chatelier, autoclave)	Expansion after setting
Compressive strength	At 3, 7 and 28 days against the grade
Chemical composition	LOI, insoluble residue, MgO, SO3, chloride

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

Why does a full cement test take a month?

Cement grades are defined by 28-day compressive strength, so the cubes must cure for 28 days. Early results at 3 and 7 days give a good indication in the meantime.

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.
