Estimation of MC in solids by electrical method

The test consists in the estimate with a resistive method of the water content of a solid wall. The moisture (or water) content in the material corresponds to the ratio between the weight difference between the material in use and the same material in the dried (anhydrous) state, in the numerator, and the weight of the material in the anhydrous state, in the denominator. In other words, moisture content is specifically defined as the ratio of the weight of water in the in-place material to the weight of the dried material after drying at 103°C. The measurement, which provides an estimate of the water content through empirical correlation, is performed using a resistance hygrometer, whose electrodes are inserted into the material by manual percussion, at the selected depth.
