Satozuka pumice sand typically contains more than 40 % non plastic fine particles Cubrinovski et al 2010 stated that the liquefaction resistance of sandy soil decreases with an increase in the non plastic fine content up to 30 % The liquefaction that happened in the Satozuka area concurs with this previous research even though the fine content is larger than

Data from 44 trials indicated that the surrogate s log 10 reduction values LRVs based on the peak concentrations were >3 in 100% 70% and 41% of the trials with the ceramic sand pumice sand and anthracite filters respectively The LRVs achieved in the ceramic sand filter trials ± were significantly greater than those in the
Cleaner lighterweight and highly angular crushed recycled glass filter media provides an amazing 25% improvement in turbidity removal over silica sand It is available in a variety of sizes depending on the exact application but can be used in
Suffusion in densely compacted Satozuka pumice sand and its impact on static loading undrained shear strength and dilation behaviour Rupali Sarmah Yoichi Watabe Article 101397
Consequently the relevance of this data to the behaviour of pumice sands is unclear An extensive experimental investigation of the dynamic response of a pumice sand was therefore undertaken The
In a soil assembly consisting of normal sand and pumice sand the voids that form between the soil grains would increase with an increase in the number of porous and angular pumice components This is due to the contact of irregular pumice particles with other constituents at their jagged contact points; the angularity of NP samples is shown in
