Aggregate Specific Gravity & Absorption
A computer controlled testing machine to determine specific gravity and absorption values of coarse and fine aggregates.
Reliable methods meet new technology
- An alternative method for measuring the specific gravity and absorption characteristics of coarse and fine aggregates
- Brings an automated, computerized test method to one of the oldest and most reliable methods of measuring displacement to find volume
- Improves repeatability and reliability of aggregate specific gravity and absorption characteristics
- Very accurate displacement values
How it works
- Uses a precision water displacement technology to quickly measure volume of an aggregate sample, and subsequently, measures change and volume over time to predict moisture absorption
- Completes specific gravity measurements on an aggregate sample in approximately 10 seconds and absorption in approximately 1 minute, with no subjective drying to SSD
- Requires only 1000g of oven dried aggregate for each test
