Hydraulic compaction of sand

Web26 apr. 2012 · Oil contamination may also change the physical properties of soil. This paper summarizes the results relating to compaction, hydraulic conductivity, and shear strength of laboratory tests conducted with oil-contaminated sand. Only one type of sand was used for the tests primarily at two relative densities of compaction; however three … Webbecause they are very impervious. Hydraulic conductivity of compacted clays is usually less than 1×10-7 cm/s. To build the liners with sand is difficult because, naturally, sand is a pervious material. Hydraulic conductivity of sand ranges from 1 to 1×10-5 cm/s (Freeze and Cherry, 1979). The hydraulic conductivity of sand can be reduced
