Moisture Measurement for aggregates and sand using ...

Moisture Measurement in Aggregates and Sand. Hydronix sensors were originally designed for the ready-mix and pre-cast concrete industries to increase the accuracy of batching and slump control. However, microwave moisture measurement has also proved to be invaluable in other industries that use sand or aggregates during processing.

Using Moisture Sensors to Control Slump - Hydronix News

Oct 21, 2020 Other than total moisture, the ratio of materials in the mix is a key factor in determining the slump of the concrete. If a batch is weighed that has 10% moisture in the sand, and 0% moisture in the gravel (by the dry weight method), the proportion of sand to gravel is 1.8:1 (see table 1). However, if a second batch is dosed with sand at 0% ...
