Difference Between Oven Dry Method and Pycnometer Method In soil mechanics and geotechnical engineering , different laboratory methods are used to determine the water content and other properties of soil. Two commonly used methods are the Oven Dry Method and the Pycnometer Method . Both methods are used in soil testing laboratories, but they differ in their procedure, equipment, and accuracy. 1. Oven Dry Method The Oven Dry Method is the most common method used to determine the water (moisture) content of soil . In this method, a wet soil sample is dried in an oven at a temperature of 105°C – 110°C until all the moisture evaporates. Principle Water present in the soil evaporates when heated in an oven. The difference between the wet weight and dry weight gives the amount of water in the soil. Uses Determining moisture content of soil Soil compaction tests Foundation engineering studies 2. Pycnometer Method The...
