Incorrect Testing Practices Lancaster NY

Conducting other tests improperly can also cause rejection of in-spec concrete at the jobsite in Lancaster. Have your drivers learn the correct methods for sampling concrete, measuring slump and air content, and making and curing strength-test specimens in the field. They're your first line of defense against needlessly rejected loads of concrete.

Erroneous results from improper testing can cause unnecessary rejection of good- quality concrete. Train your drivers to recognize some of the more common testing errors.

They're your first line of defense against needlessly rejected loads of concrete.Some improper practices are:

  • 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
  • Failure to use an aggregate correction factor
  • Use of the pressure meter to measure air content
  • 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
  • Measuring the difference between the top of the cone and the highest or lowest point on the slumped specimen
  • Fai...
