In-situ crushing resistance testing is carried out to assess compaction using the BRE Screed Tester Apparatus. The test method consists of subjecting the surface of the screed to four consecutive blows from a 4kg (or 2kg) weight dropped vertically through a height of 1m onto a foot 500mm² in area and then measuring the depth of indentation.

The ASTM C39 test standard for compressive strength of concrete cylinders requires numerous checks for dimensions of the concrete cylinders and alignment during testing. The manual instructs and illustrates acceptable practices to properly perform these measurements. C39 gives basic requirements for concrete compression testing machines, but the manual provides non-mandatory information on the ...
UKCSA's performance test stipulates that: the average crushing strength of 3 cubes tested to BS EN 12390: Part 3 shall not be less than 35 MPa at 28 days old. No individual cube is to have a strength less than 28 MPa.
