CSIRO PUBLISHING | Soil Research
Pumice and biochar were completely separated from the sandy soil and then dried at 30°C for 72 h to a constant weight. Prior to chemical characterisation, pumice and biochar particles, at the beginning and at the end of the experiment, were ground to a size < mm.
Geotechnical Properties of a Pumice Sand ScienceDirect
The pumice sand found in the North Island of New Zealand has properties which lie beyond those usually associated with cohesionless soils. The grains are very soft and the sand has a high void ratio, thus forming a compressible material. This paper presents the results of a series of drained triaxial and K0 tests on dry pumice sand.
