Do you use moisture probes or nationally recognized ASTM manual test methods for determining moisture? Print 1 2 3 4 5 page sstarting from page current page. No other units of measurement are included in this standard. The electronic file may not be reproduced in any way.

ASTM C – 13 – Standard Test Method for Total Evaporable Moisture Content of Aggregate by Drying

Probes can be placed in bins just under the discharge gates and above the weigh belt or directly in the path of the aggregates after they have dropped onto the belt. Probes can also be placed in the mixer. For specific precautionary statements, see 5. 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.

It will asm measure the moisture in the c566 sample more reliably than the sample can be made to represent the aggregate supply. Work Item s – proposed revisions of this standard. Comments How is the price for the probe including installation charge? Such water is not evaporable and is not included in the percentage determined by this test asgm.

There are several types of probes on the market today. However, they significantly reduce the frequency of manual tests. 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.

For SCC processes made without moisture probes or meters and automatic mixing water adjustment systems, the aggregate surface moisture content must be determined at least once per day prior to the batch and once every four hours after the first batch.

So the real question is: Historical Version s – view previous versions of standard. Automated input allows the plant to make fine adjustments to mix proportions and leads to a much narrower set of final batched concrete tolerances.

By measuring the reflection points, a sine wave, or data pattern, is then v566 to guarantee an accurate moisture reading. However, with either choice, accurate accounting of moisture in aggregates is essential to keep your mix on target and within specified limits.

Controlling Moisture to Ensure Quality

We have no amendments or corrections for this standard. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The probe sends radar waves into the sand and measures the reflection returned. 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.

Remember me for one month. 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.

We could make strong cases for both methods. These technologies allow automatic moisture evaluations of materials. Lastly, radar-type probes consist of guided radar waves to facilitate measurements.

Probes do not eliminate the need to perform manual tests for verification of aggregate moisture. This standard is not included in any packages.
