SIZE ANALYSIS Purpose : This test is performed to determine the percentage of different grain sizes contained within a soil. The mechanical or sieve analysis is performed to determine the distribution of the coarser, larger-sized particles. Standard Reference : ASTM D 422 - Standard Test Method for Particle-Size Analysis of Soils Significance : The distribution of different grain sizes affects the engineering properties of soil. Grain size analysis provides the grain size distribution, and it is required in classifying the soil. Equipment : Balance, Set of sieves, Cleaning brush, Sieve shaker.

Test Procedure: Sieve Analysis: (1) Write down the weight of each sieve as well as the bottom pan to be used in the analysis. (2) Record the weight of the given dry soil sample. (3) Make sure that all the sieves are clean, and assemble them in the ascending order of sieve numbers (#4 sieve at top and #200 sieve at bottom). Place the pan below #200 sieve. Carefully pour the soil sample into the top sieve and place the cap over it. (4) Place the sieve stack in the mechanical shaker and shake for 10
