Controlling Moisture to Ensure Quality
If the document is revised or amended, you will be notified by email. Thank you for your comment Sufian. This is to ensure that the moisture adtm of aggregates are accounted for correctly. It will generally measure the moisture in the test sample more reliably than the sample can be made to represent the aggregate supply. Such water is not evaporable and is not included in the 5c66 determined by this test method.

For additional information on moisture probes, please contact the NPCA technical services department at Enter your personal account email address to request a password reset: Then, take the pair of cylinders and break them.
Automated input allows the plant to make fine adjustments to mix proportions and leads to a much narrower set of final batched concrete tolerances. However, they significantly reduce the frequency of manual tests. Add to Alert PDF. The probe sends radar waves into the sand and measures the reflection returned. These tests are typically performed daily by the quality control technician and may occur more than once per day depending on aggregate consumption, the prevailing weather conditions, whether or not bins are exposed to the elements and project-specific requirements.

The use of moisture probes for determining aggregate moisture has been widely used as an accepted practice in precast plants across the country for more than 25 years. We have no ashm or corrections for this standard. aatm
