Reference
Results mass based distribution:
First sieving over a 2 mm sieve
- The resulting material (11.36 % < 2 mm of the total sample) was then sieved over a 1 mm sieve.
- The resulting material (2.91 % < 1 mm of the entire sample) was then sieved over a 500 µm sieve.
Results from volumetric distribution ISO13320:
From the fraction smaller than 500 µm (1.21 % < 500 µm of the total sample), a dry particle size distribution was performed by laser diffraction (Malvern mastersizer 3000).
