Concrete and aggregate testing
Does the concrete delivered meet the specification, and are the aggregates fit for use? We test fresh concrete on site, and hardened specimens, aggregates and paving blocks in our laboratory.

We test fresh concrete on site and hardened concrete specimens in our laboratory, together with aggregates for concrete and road construction and concrete paving blocks. Compressive strength is determined on our UTEST 2000 kN machine, verified as Class 1 to TS EN 12390-4:2025.
What we test
| Test | Standard | Where | What you get |
|---|---|---|---|
| Fresh concrete: slump, density and air content | TS EN 12350-2:2019 TS EN 12350-6:2019 TS EN 12350-7:2019 | Field | Slump, density and air content on delivery, before placing |
| Hardened concrete: density and compressive strength of cubes and cylinders | TS EN 12390-3:2019 TS EN 12390-4:2025 TS EN 12390-7:2019 | Lab | Density and compressive strength of each specimen |
| Aggregate grading, percentage of crushed particles, shell content and methylene blue value | TS EN 933-1:2012 TS EN 933-5:2022 TS EN 933-7:2000 TS EN 933-9:2022 | Lab | Grading curve and summary of aggregate properties |
| Los Angeles fragmentation resistance, loose bulk density and voids, water content, particle density and water absorption, and filler particle density | TS EN 1097-2:2020 TS EN 1097-3:1999 TS EN 1097-5:2009 TS EN 1097-6:2022 TS EN 1097-7:2022 | Lab | Fragmentation resistance and physical properties of the aggregate |
| Flakiness and elongation indices, and clay lumps and friable particles | BS 812 (shape indices) ASTM C142/C142M-17(2023) | Lab | Particle shape indices and clay lump content |
| Concrete paving block testing | TS 2824 EN 1338:2005+T1:2006 | Lab | Test report for each paving block sample |
Why it matters
Fresh concrete tests on delivery confirm that consistence and air content meet the specification before the concrete is placed, while rejection is still possible. Compressive strength results on standard specimens are the basis of conformity assessment for concrete. Aggregate grading, cleanliness, particle shape and fragmentation resistance directly affect the strength, workability and durability of concrete and road layers.

- Aggregate samples delivered to our laboratory; we confirm the quantity needed when quoting
- The supplier or source of each concrete, aggregate or paving block sample
Frequently asked questions
Can you test fresh concrete when the truck arrives on site?
Yes. We measure slump, density and air content on delivery, so consistence and air content are checked against the specification before the concrete is placed, while rejection is still possible. We work on weekdays and weekends around your pour schedule.
Which machine do you use for compressive strength?
We test cubes and cylinders to TS EN 12390-3:2019 on our UTEST 2000 kN machine, verified as Class 1 to TS EN 12390-4:2025. Its calibration certificate is available on request.
How long does it take to get results?
The turnaround depends on the tests requested; we confirm it with your quote. Compressive strength results follow the test ages specified for your specimens.
How can I check that a report is genuine?
Every report carries a QR code, a report number and a verification code. Anyone can check it on our Verify a Report page.
