The qualitative term of 'hygroscopic materials' used in this manuscript includes materials classified as hygroscopic (H-3) or very hygroscopic (H-4). Since the end of the 30% RH step is the zero point (or baseline), any weight loss/gain recorded during the 30% RH step is additive to the weight gain at 80% RH. In some cases (evaporative ...

to free the finer material that adheres to the coarser particles. Separate the ground soil into two fractions by means of the 0.425-mm (No. 40) sieve, and regrind the material retained on the sieve. When repeated grinding produces only a small quantity of soil passing the 0.425-mm sieve, discard the material retained on the 0.425-mm sieve.
