# Specific Gravity and Water Absorption Test Calculator

The specific gravity of an aggregate is defined be a measure of strength or quality of the material. Stones having low specific gravity are generally weaker than those with the high. The percent of water necessary to add to the aggregate to obtain SSD is called as water absorption. Use our online Specific gravity and water absorption test calculator to do water absorption of aggregates calculation based on the weight of dry piece soaked in fluid and weight of dry piece in the fluid.

## Water Absorption of Aggregates Calculation

The specific gravity of an aggregate is defined be a measure of strength or quality of the material. Stones having low specific gravity are generally weaker than those with the high. The percent of water necessary to add to the aggregate to obtain SSD is called as water absorption. Use our online Specific gravity and water absorption test calculator to do water absorption of aggregates calculation based on the weight of dry piece soaked in fluid and weight of dry piece in the fluid.

#### Formula:

Water Absorption = (S - W / W) x 100 Where, S = Weight of Dry Piece Soaked in Fluid W = Weight of Dry Piece in Fluid

### Example:

Calculate the water absorption of aggregates based on the weight of dry piece soaked in fluid of 50 and weight of dry piece in fluid of 30.

#### Solution:

Water Absorption = (50 - 30 / 30) x 100
= 66.6667
