Why grain distribution is essential for material performance
Grain distribution shows how the different grain sizes in a granular material are structured. This determines properties such as stability, bearing capacity and workability. Proper distribution ensures that larger grains are filled by finer particles. This creates fewer voids and improves the cohesion of the material.
With an understanding of grain distribution, you make better informed choices for applications in road construction and foundations, for example.
How we accurately analyze grain distribution
We determine grain distribution by sieving the material into different fractions. Each fraction is then weighed separately. Based on these measurements, we establish a sieve curve. This is a graphical representation of the distribution of grain sizes within the sample.
