  • Minimizing Gradation Testing Variability

    It seems that many of the field labs had performed gradation tests with worn sieves. While most differences were minor, they introduced a degree of unnecessary variability when combined. How can we can minimize our testing variables on these large projects?

  • Faster Testing for Fine Aggregrate Quality

    Q. The last few seasons we've had difficulty controlling our water demand and our yields due to the sand's variability in absorption and specific gravity. Our quality control problem is compounded because our stockpile area is rather small. So by the time the lab sends us the sample results, the...

  • Proper Coring Techniques

    Q. We are involved in a quality claim in which the testing lab reports the hardened concrete did not achieve the specified design strength. Our testing lab broke cylinders from that same job and all achieved proper strength. We are confident that we will achieve proper strength if the coring is...
