What we say, we can show.
Independent NABL-accredited labs have tested AIWON blocks. On average they found a compressive strength of 4.85 N/mm² — 21% above the IS 2185 Grade 1 minimum — at 630 kg/m³. Here are the results, the licences and the way to check a certificate.
The block’s passport
A licence is only worth the authority behind it. Each stamp is issued by one — the Bureau of Indian Standards, the CII Green Products Council, an accredited ISO auditor, the Indian Green Building Council. Tap a stamp to read it and open the original.
Lab results, averaged
One number per test: the average of the independent lab reports, on the scale IS 2185 uses. The green band is where the standard wants the result; the bar shows the spread between labs.
How the averages are made
Every report comes from a NABL-accredited laboratory testing 600 × 200 × 150 mm AIWON blocks. A result is counted once the lab has issued it; drying shrinkage takes weeks, so it has fewer reports than strength and density.
Need the full reports?
Engineers, architects and project consultants can have the individual lab reports for their approval file.
And in our own lab, every day
From the plant lab this week
Our own lab tests blocks from every production control unit. As soon as a unit is accepted in BRICKCEM ONE, its results appear here — nobody edits this table by hand.
Check a test certificate
Every AIWON delivery can come with a Brickcem material test certificate. Type its number to see what our records say about it. A certificate we cannot find is not ours.
Test it yourself
Ask for sample blocks and send them to any NABL lab you trust.
