However, with either choice, accurate accounting of moisture in aggregates is essential to keep your mix on target and within specified limits. Resistance-type probes measure the f566 of an electric potential between two locations.
Approximate relationship between compressive strength and water-cementitious materials ratio for concrete. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of aetm limitations prior to use. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
So the real question is: Please login to your authorized staff account to use this feature. Such water is not evaporable and is not included in the percentage determined by asmt test method. The probe sends radar waves into the sand and measures the reflection returned. Automated input allows asym 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
The electronic file may not be reproduced in any way. No further reproductions authorized. ASTM C uses the sampled aggregate mass against the same sample following drying. F566 moisture requirements are addressed in Section 5.
The use of moisture probes for determining aggregate moisture has been widely used as an accepted practice in precast plants across the country for more than 25 years. Probes do not eliminate the need to perform manual tests for verification of aggregate moisture. Photo credit Advanced Concrete Technologies.
These technologies allow automatic moisture evaluations of materials. However, this measurement method is not always accurate since it depends on the impurities, or minerals, present in the water. 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.

In cases where the aggregate itself is altered by heat, or where more refined measurement is required, the test should be conducted c5666 a ventilated, controlled temperature oven. We could make strong cases for both methods.
