Sand Bath Method

This is a field method used in the determination of the rough value of water content in the field, where the facility of an oven is not available.
Procedure:

1. The soil sample collected in the container is placed on a sand bath.

2. A kerosene stove is used to heat the sand bath.

3. The side gets dry in ½ - 1 hour of time.

4. The water content is determined using the above equation:(3.1).

Limitations:

1. No control on temperature. Therefore, higher temperatures may break the crystalline structure of soils.

2. Not suitable for organic soils or soils containing gypsum in higher percentages.
