Coarse aggregate water absorption

Calculate absorbed water as a percentage of oven-dry mass from corresponding SSD and dry observations.

Observations and units

• Saturated surface-dry mass (g)
• Oven-dry mass (g)

Calculation

Absorbed water = SSD mass − oven-dry mass; absorption = 100 × absorbed water / oven-dry mass.

Method reference and limitations

IS 2386 (Part 3):1963, clauses 2.2.4 / 2.3.4. Coarse aggregate only. SSD preparation, particle size, soaking and oven conditions must follow the selected method. Enter independent determinations of the same material. Specific gravity and fine-aggregate SSD determination are excluded.

Calculation and reporting rules audited within the documented profile; physical test execution and specification acceptance remain the operator’s responsibility. Independent qualified review is not recorded. No certificate or compliance decision.
