The alternative designation given in parentheses is for information only and does not represent a different standard sieve size. In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise. Content only available by subscription.

However, axtm either choice, accurate accounting of moisture in aggregates is essential to keep your mix on target and within specified limits. Excess moisture in fine aggregates can easily account for a gallon of water. Thank you for your comment Sufian.

For additional information on moisture probes, please contact the NPCA technical services department at Register for a trial account. Aggregate moisture requirements are addressed in Section 5. To maintain a constant flow of material over the moisture probe, it can be positioned under the aggregate dosing gate. We could make strong cases for both methods. Automated input allows the plant to make fine adjustments to mix proportions and leads to a much narrower set of final batched concrete tolerances.

Controlling Moisture to Ensure Quality

This is to ensure that the moisture fluctuations of f566 are accounted for correctly. E xcessive water can destroy a concrete mix design.

Approximate relationship between compressive strength and water-cementitious materials ratio for concrete. No items in cart. The probe sends radar waves into the sand and measures the reflection returned. Your email address will not be published. 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.

In addition, the language states that slump flow testing will take place for every three batches of SCC produced. ASTM C uses the sampled aggregate mass against the same sample following drying.

Then, take the pair of cylinders and break them. 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.

We have no amendments or corrections for this standard. However, they significantly reduce the frequency of manual tests.

Remember me for one month. This standard is also available to be included in Standards Subscriptions. For specific precautionary statements, see 5. The right to asym the electronic files of ASTM Standards is aastm purposes of viewing for individual use only.

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. No other units of measurement are included in this standard. Some aggregate may contain water ast is chemically combined with the minerals in the aggregate. No other satm of measurement are included in this standard.

However, this measurement method is not always accurate since it depends on the impurities, or minerals, present in the water. Enter your account email address to request a password reset: Historical Version s – view previous versions of standard.
