Question

Why soil samples are dried for 8 hours at 105* to get moisture percentage?

Answer 1

In Geotechnical Engineering practice, a soil is oven-dried to remove the moisture from it. This is done when

one needs to use an oven-dried soil for further testing. For such a case, large quantities of soil (often in trays) is kept in the oven.one needs to determine the moisture content (aka water content) of the soil. For such a case, only a small quantity of soil is required to be oven-dried. The moisture content is determined as - if M is the mass of the soil in its natural condition, Ms is the mass of the soil after over drying, then, moisture content = (M-Ms)/Ms. Moisture content is reported in percentage.
