To conduct a sieve analysis, samples are oven dried for at least 24 hours. The soil is placed and shaken through a stack of sieves with openings of decreasing size from top to bottom. The mass of particles retained in each sieve is determined. Results showed that the particle–size distribution curve of coarse...

    Date: March 3, 2011 Introduction: Hydrometer analysis is used to determine the grain-size distribution of a soil which is similar to the sieve analysis done in an earlier lab. Hydrometer analysis can be combined with the sieve analysis to determine the amounts (percents) of fines (silts and clays) in a sample. The hydrometer analysis doesn’t require the soil to be passed through a series of sieves like in the sieve analysis. The analysis measures the rate of sedimentation. The larger the...
