In addition, the language states that slump flow testing will take place for every three batches of SCC produced. One of the biggest advantages over manual methods is astj obtain values of aggregate moisture as they are batched in real time or with very minimal delay.
Aetm aggregate may contain water that is chemically combined with the minerals in the aggregate. Note 1 — Sieve size is identified by its standard designation in Specification E For specific precautionary statements, see 5. Leave a Reply Cancel reply Your email address will not be published.

Controlling Moisture to Ensure Quality
Standards Subsctiption may be the perfect solution. If the document is revised or amended, you will be notified by email.
Subscription pricing is determined by: No other units of measurement are included in this aatm. Discovering the detrimental effects can be easily seen in a small-scale experiment using compressive-strength cylinders and a common mix design.
Approximate relationship between compressive strength and water-cementitious materials ratio for concrete. No items in cart.

Please first log in with a verified email before subscribing to alerts. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Microwave-type probes do not rely on measuring impurities, making it a better option to use, he said. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. We have no amendments or corrections for this standard. 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.
As the voice of the U. This standard is also available to be included in Standards Subscriptions. However, they significantly reduce the frequency of manual tests. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.
By measuring the reflection points, a sine wave, or data pattern, is then created to guarantee an accurate moisture reading. You may delete a document from your Alert Profile at any time.

Excess moisture in fine aggregates can easily account for a gallon of 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 cc566 use. 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.
It will generally measure the moisture in the test sample more reliably than the sample can be made to represent the aggregate supply. The probe sends radar waves into the sand and measures the reflection returned. There were no books found for c66 applied awtm filters.
ASTM grants you a license as follows: Remember me for one month. Enter your account email address to request a password reset: We could make strong cases for both methods.
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. This information is then fed directly into the automated mixing water batch controller of the plant.
