Why water absorption and particle density are important
Particle density and water absorption provide important information about the quality and performance of aggregates. These properties affect strength, durability and workability, among other things. By determining these values accurately, you will know if a material is suitable for your application and avoid problems in construction or use.
How we measure accurately
Depending on the grain size, we determine the density and water absorption using pycnometers or underwater weighing.
With a pycnometer, we determine the specific gravity of the material based on:
- Water displacement
- A known volume
- The weight of the material
We measure different densities:
- Apparent density
- Kiln-dry density
- Saturated-surface dry density
After a 24-hour soaking period, we determine the water absorption of the material.
