This procedure adopts the following four methods according to the particle size and gradation of the soil. 1. Sieve analysis method: suitable for soil with particle size up to 0.075mmn. 2. Density meter method; suitable for soil with particle weight less than 0.075mm. 3. Pipette method: suitable for soil with dry particle size less than 0.075mm. 4.
