Bulking of Sand The Construction CivilArtificial Islands Construction of Artificial Island

Graphical representation of bulking of sand is shown below When the moisture content of sand is increased by adding more water the sand particles pack near each other and the amount of bulking of sand is decreased Thus it helps in determining the actual volume of sand the dry sand and the sand completely filled with water will have the exact volumeIntroduction to Artificial islands An artificial island is an island constructed by man rather than created by natural means They are constructed by expanding the existing islets and by construction on existing reefs or merging some natural islets into a bigger island
