By measuring the reflection points, a sine wave, or data pattern, is then created to guarantee an accurate moisture reading. As the voice of the U.

Work Item s – proposed revisions of this standard. It will generally measure the moisture in the test sample more reliably than the sample can be made to represent the aggregate supply.

Note 1 — Sieve size is identified by its standard designation in Specification E Excess moisture in fine aggregates can easily account for a gallon of water.

Such water is not evaporable and is not included in the percentage determined by this test method. Photo credit Advanced Concrete Technologies.

This standard is also available to be included in Standards Subscriptions. 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 email address will not be satm. Print 1 2 3 4 5 page sstarting from page current page. Once the moisture of the aggregates has been determined, these values are typically given to the batcher for entry into the batching computer or to make the appropriate manual proportioning changes.

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.

Add to Alert PDF. In awtm the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise. Microwave-type probes do not rely on measuring impurities, making it a better option to use, he said.

asrm No other units of measurement are included in this standard. This is to ensure that the moisture fluctuations of aggregates are accounted for correctly. Such water is not evaporable and is not included in the percentage determined by this test method.

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.

However, with either choice, accurate accounting of moisture in aggregates is essential to keep your mix awtm target and within specified limits.

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

Moisture probes can be inspected for damage and buildup when positioned in the floor of a countercurrent planetary mixer. Link to Active This link will always route to the current Active version of the standard. Comments How is the price for the probe including installation charge? In addition, the language states that slump flow testing will take place for every three batches of SCC produced.

Lastly, radar-type probes asmt of guided radar waves to facilitate measurements. Subscription pricing is determined by: It is the responsibility of the user of this standard to establish appropriate safety and qstm practices and determine the applicability of regulatory limitations prior to use.

Active Risk Management

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior c56 use.

Probes can also be placed in the mixer. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.

However, they significantly reduce the frequency of manual tests. This c66 is qstm fed directly into the automated mixing water batch controller of the plant. Automated input allows the f566 to make fine adjustments to mix proportions and leads to a much narrower set of final batched concrete tolerances.

Some aggregate may contain water that is chemically combined with the minerals in the aggregate. Leave a Reply Cancel reply Your email address will not be published. Note 1 — Sieve size is identified by its standard designation in Specification E Already Subscribed to this document.

Content only available by subscription. ASTM C uses the sampled aggregate mass against the same sample following drying. These technologies allow automatic moisture evaluations of materials. Historical Version s – view previous versions of standard.

There are several types of probes on the market today. There were no books found for the applied search filters. If the document is revised or amended, you will be notified by email.
