Probes can be placed in bins just under the discharge sstm and above the weigh belt or directly in the path of the aggregates after they have dropped onto the belt.
To maintain a constant flow of material over the moisture probe, it can be positioned under the aggregate dosing gate. Once the moisture of the aggregates has been determined, these values are typically asym to the batcher for entry into the batching computer or to make the appropriate manual proportioning changes.
If the document is revised or amended, you will be notified by email. No other units of measurement are included in this standard.

In cases where the aggregate itself is altered by heat, or where more refined measurement is required, the test should be conducted using a ventilated, controlled temperature oven.

However, with either choice, accurate accounting of moisture in aggregates is essential to keep your mix on target and within specified limits. One of the biggest advantages over manual methods is they obtain values of aggregate moisture as they are batched in real time or with very minimal delay.
Aggregate moisture requirements are addressed in Section 5. Photo credit Advanced Concrete Technologies.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of c566 limitations prior to use. However, this measurement method is not always accurate since it depends on the impurities, or minerals, present in the water.
So the real question is: The user of this test method should determine by trial if rapid drying methods provide sufficient accuracy for the intended use when drying large size particles. Lastly, radar-type probes consist of guided radar waves to facilitate measurements. ASTM grants you a awtm as follows: No further reproductions authorized.

It will generally measure the moisture c5666 the test sample more reliably asgm the sample can be made to represent the aggregate supply. Link to Active This link will always route to the current Active version of the standard.
The subsection goes on to state that when aggregate bins are fitted with moisture probes or meters, aggregate surface moisture content shall be determined a minimum of once per week in order to validate probe calibration. Your Alert Profile lists the documents that will be monitored.

For additional information on moisture probes, please contact the NPCA technical services department at Work Item s – proposed revisions of this standard.

For one cylinder, increase the amount of mix water and keep all other parameters the same. Leave a Reply Cancel reply V566 email address will not be published. By measuring the reflection points, a sine wave, or data pattern, is then created to guarantee an accurate moisture reading. Already Subscribed to this document.
