As the voice of the U. No items in cart. This standard is also available to be included in Standards Subscriptions. Remember me for one month. Print 1 2 3 4 5 page sstarting from page current page. So the real question is: E xcessive water can destroy a concrete mix design. 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. Note 1 — Sieve size is identified by its standard designation in Specification E 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.

Register for a trial account. However, this measurement method is not always accurate since it depends on the impurities, or minerals, present in the water. 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 to use.

For additional information on moisture probes, please contact the NPCA technical services department at However, with either choice, accurate accounting of moisture in aggregates is essential to keep your mix on target and within specified astk.

To maintain a constant flow of material over the moisture probe, it can be positioned under the aggregate dosing gate. Comments How is the price for the probe including installation charge? Probes do not eliminate the need to perform manual tests for verification of aggregate moisture.

Probes can be placed in bins just under the discharge gates and above the weigh belt or directly in the path asttm the aggregates after they have dropped onto the belt. In cases where the aggregate itself is altered by heat, or where more refined measurement x566 required, the test should be conducted using a ventilated, controlled temperature oven.

Resistance-type probes measure the resistance of an electric potential between two locations. Some aggregate may contain water that is chemically combined with the minerals in the aggregate. Already Subscribed to this document. This information is then fed directly into the automated mixing water batch controller of the plant.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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 qstm the first batch.

The alternative designation given in parentheses is for information only and does not represent a different standard sieve size. Wstm probes do not rely on measuring impurities, making it a better option to use, he said.

Excess moisture in fine aggregates can easily account for a gallon of water.

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

Controlling Moisture to Ensure Quality

The electronic file may not be reproduced in any way. 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.
