E xcessive water can destroy a concrete mix design. It is the responsibility of the 5c66 of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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.
Already Subscribed to this document. Comments How is the price for the probe including installation charge? Then, take the pair of cylinders and break them.

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. Moisture probes can be inspected for damage and buildup when positioned in the floor of a countercurrent planetary mixer.
Such water is not evaporable and is not included in the percentage determined by this test method. For one cylinder, increase the amount of mix water and keep all other parameters the same.

There are several types of probes on the market today. It will generally measure the moisture in f566 test sample more reliably than the sample can be made to represent the aggregate supply. Excess moisture in fine aggregates can easily account for a gallon of water.

The electronic file may not be reproduced in any way. However, this measurement method is not always accurate since it depends on the impurities, or minerals, present in the water.
You can download and open this file to your asmt computer but DRM prevents opening this file on another computer, including a networked server.
One of the biggest advantages over manual methods is they obtain values of aggregate moisture as they are batched in real time asym with very minimal delay.
The user of this test method should determine by trial if rapid drying methods provide sufficient accuracy for the intended use when drying large size particles. Register for a trial account.
