Influence of Fiber Content and Length on Engineering Properties of MICP-Treated Coral Sand
, 2020Microbially induced calcite precipitation (MICP) can improve the engineering properties of coral sand. The dry density, permeability, unconfined compressive strength (UCS), tensile strength, and microstructure were measured to investigate the effect of ...

Reports on Progress in Physics, 2012
Many desert sand dunes emit a loud sound with a characteristic tremolo around a well-defined frequency whenever sand is avalanching on their slip face. This phenomenon, called the 'song of dunes', has been successfully reproduced in the lab, on a smaller scale.

Trading Sand, Undermining Lives: Omitted Livelihoods in the Global Trade in Sand
Annals of the American Association of Geographers, 2019Sand is a scarce resource, extracted from rivers and coasts at rates that exceed its natural renewal. Yet, little is understood about the political economy of sand extraction, the livelihood vulnerabilities produced, or why sand grabbing is occurring at ...

No treatise on metal casting production would be complete without reference to the most widely used moulding and coremaking media — sand. With the vast range of sand moulding and coremaking processes available, perhaps the engineer today could be excused if he feels this facet of casting production should be termed ‘granular witchcraft’. However, there
