  • Excessive prewetting, leaving surplus water in the container
  • Sampling from the form into which the concrete has been placed
  • Failure to remix the concrete sample in the sample container before starting the tests

  • Base plate not large enough, allowing high-slump concrete to spill over the edge of the plate
  • Base not level
