Moisture content determination by rapid moisture meter
1. Objective
water content determination generally takes 16 to 24 hours by oven drying method. To quickly determine the water content at site, use of rapid moisture meter is very advantageous. In this method, water content is determined from the gas pressure developed by the reaction of calcium carbide (absorbent) with free water of the soil sample. From the calibrated scale of the pressure gauge, the percentage of water on total (wet) mass of soil sample is obtained and the same is converted to water content on dry mass of soil.
2. Apparatus required
