Diatomaceous soils: a less than cromulent engineering material
Diatoms are unicellular microalgae found in both fresh and salt water around the world, and their fossils have a large impact on geotechnical behaviour of soil deposits. The diatom cell wall, called a frustule, is comprised of hydrated silicon dioxide. The frustule has very high intra particle porosity and an intricately patterned porous surface. Previous studies show non-standard geotechnical behavior for diato- maceous soils: they are extraordinarily porous (sometimes up to 90% voids by volume), have high liquid limits and plastic limits, and are very compressible, yet they exhibit large shear strengths. This manuscript provides a broad review of previous work on the engineering behavior of diatomaceous soils. This review is then supplemented by laboratory and in-situ characterization results for diatomaceous soils found in the northwest United States which show that standard geotechnical interpretations and correlations are not ap- propriate for diatomaceous soils.
