MOISTURE CONTENT TEST OF SOIL

MOISTURE CONTENT TEST OF SOIL(IS-2720-PART-2-1973)

Moisture Cans

OBJECTIVE

For determination of the moisture content of soil by oven drying method.

EQUIPMENT’S & ACCESSORIES

• Oven (1050C to 1100C min.)
• Metal container
• Balance (0.01 g accuracy)

PROCEDURE

1. The number of the container is recorded, cleaned, dried and weighed.(W1)
2. About 15-30 g of soil is placed in the container and the weight of soil with the sample is recorded.(W2)
3. The can with the soil is placed in oven for 24hours maintained at a temperature 1050 to 1100C.
4. After drying the container is removed from the oven and allowed to cool at room temperature.
5. After cooling the soil with container is weighed.(W3) 

CALCULATION

         

W1=Mass of container, g

W2=Mass of container and wet soil, g

W3=Mass of container and dry soil, g

REPORT

The water content of the soil is reported to two significant figures.

SAFETY & PRECAUTIONS

• Use hand gloves while removing containers from oven after switching off.
• The soil should be loosely placed in the bin, so as to allow easy evaporation of moisture
• Over heating should be avoided.
• Oven dry soil should not be kept open to the atmosphere (for cooling) as it may absorb moisture from atmosphere
• Ensure the identification number on the base and the lid of the bin is same
