  • 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

  • Failure to firmly support the base plate
  • Base plate not large enough, allowing high-slump concrete to spill over the edge of the plate
  • Base not level
  • Dampening the slump cone and base leaving a puddle of water on the base
