  • Sieve analysis Wikipedia

    A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass

  • Compaction of Soil Purpose Effects & Factors Affecting

    Compaction is the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio The principal reason for compacting soil is to reduce subsequent settlement under working loads As water is added to a soil ( at low moisture content) it becomes easier for the particles to move past one another during the application of the compacting
