Concrete and aggregate testing

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.

What we do

  • Fresh concrete: slump (TS EN 12350-2), density (TS EN 12350-6) and air content (TS EN 12350-7)
  • Hardened concrete: density (TS EN 12390-7) and compressive strength of cubes and cylinders (TS EN 12390-3)
  • Aggregate grading, percentage of crushed particles, shell content and methylene blue value (TS EN 933 series)
  • Los Angeles fragmentation resistance, loose bulk density and voids, water content, particle density and water absorption, and filler particle density (TS EN 1097 series)
  • Flakiness and elongation indices (BS 812) and clay lumps and friable particles (ASTM C142)
  • Concrete paving block testing (TS EN 1338)

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.

What you receive

  • Test report to the relevant standard for each sample or set of specimens
  • Sample identification: date, pour location or element, and supplier or source
  • Grading curves and a summary table of aggregate properties
  • Calibration certificate for our compression machine on request
