How To Moisture Content Test

 

Moisture Content

Moisture content is crucial when the sand is tested for construction. More moisture can weaken the concrete. Also if there is more moisture it affects the workability. The moisture content tests mainly involve the sand sample weighting before and after drying them in the oven. This helps in the determination of moisture percentage, ensuring optimal sand moisture levels for construction.

The apparatus used in this analysis are metal tray, weighing Scale, and oven. The procedures involved in the process are preparation of the sample, initial weighting, drying, final weighting, and calculation.

Formula used is

moisture content = (initial weight – final weight/initial weight)*100.

For example: 

Wet sand sample weight (W) = 1200g

Oven-dried sand sample weight (Wd) = 1000g

Moisture content: (1200−1000/1200)×100 = 16.67%

From this, we can see that the sand sample is 16% moisture content by weight.
