Laboratory tests for permeability of sand during liquefaction

WebbThe constant head permeability test is a laboratory experiment conducted to determine the permeability of soil. The soils that are suitable for this tests are sand and gravels. Soils with silt content cannot be tested with this method.The test can be employed to test granular soils either reconstituted or disturbed. Objective and Scope On a prepared mould surface as a sample, permeability can be checked with use of a mould permeability attachment to permeability meter, readings such obtained are of relative permeability, and not absolute permeability. The relative permeability reading on a mould surface is only used to gauge sample-to … Visa mer Permeability is a property of foundry sand with respect to how well the sand can vent, i.e. how well gases pass through the sand.
