The bulk density of plaster is approximately half that of quartz sand, for the same handling and humidity (Fig. 4 B). Conversely, the inferred porosity of quartz sand is 35–55 vol% and that of plaster is 65–78 vol% (Fig. 4 C). Previously, van Gent et al. (2010) found a similar porosity of ~75 vol% for gypsum powder.

Experiments on compressibility and void ratio (Eq. 7) attest that the samples from the test field Alpha Ventus (quartz sand) have the lowest void ratios of the measured samples ranging from 0.81–0.83 for loads ≤3,100 kPa. The coarser quartz sand from the Innenjade tidal channel shows slightly higher void ratios ranging from 0.90–0.93.
