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% ...
