Allow the shaker to work 10-5 minutes – use the clock here..! sait sieve sizes. The analysis of foundations o… Grain-size analysis of soils containing relatively large particles is accomplished using sieves. The portion of the soil sample retained on 4.75-mm IS Sieve, selected as given in Preparation of Sample;shall be weighed and the mass recorded as the mass of the sample uncorrected for hygroscopic moisture. The engineering soil classification systems divide soil particles on the basis of size İnto categories- boulders, cobbles, gravel, sand, silt and clay. In sieve analysis, the particle size distribution is defined using the mass or volume. The grain size distribution of any soil can be determined using the grain size analysis, also called mechanical analysis. The soil soaked specimen should be washed thoroughly over the nest of sieves, nested in order of their fineness with the finest sieve (75-micron IS Sieve) at the bottom. After the experiment, this report concludes that the soil sample that was analyzed The fraction retained on each sieve should be emptied carefully without any loss of material in separate trays. Additionally, frost sus- ceptibility of soils can be fairly accurately predicted from the results of grain-size analysis. There are two methods generally used to find the particle-size distribution of soil: (1) sieve analysis - for particle sizes larger than 0.075 mm in diameter, and (2) hydrometer analysis - for particle sizes smaller than 0.075 mm in diameter. The standard grain-size analysis test determines The sieve analysis / grain size analysis is a test used in civil engineering to access the particle size distribution of a granular material. determine the distribution of the coarser, larger-sized particles, and the hydrometer method is used to determine the distribution of the finer particles. TEST METHOD FOR THE PARTICLE SIZE ANALYSIS OF SOILS BY HYDROMETER METHOD 1. Soil particles have sizes ranging from greater than 200 mm down to less than 0.002 mm. The main importance of sieve analysis in civil engineering can be listed as follows: 1. Dry sieving method is considered mostly and here the testing particles (specimen) are in dry state. ����������� 4.mechanicalSieve Shaker ����������� �The grain size analysis is an attempt todetermine the relative proportions of different grain sizes which make up agiven soil mass.

Measures such as thousand grain weight are fast, but do not give an indication of variation within a sample. Why Hydrometer is used for grain size analysis of fine grained soil? Test Procedure. In a soil, the gravel, sand, silt and clay fractions are recognize as containing particles Procedure 1.The soil fractions retained on and passing 4.75mm Sieve shall be taken separately for the analysis. The procedure is a modification of AASHTO Test Method T-88-86. Abstract. and left for soaking. The purpose of this testing was to confirm the consistency of the sand used at various test sites and to provide updated minimum and maximum density index values. The characters of particle such as bulk density, physical stability, permeability and many more are decided by its size. 3. Grain Size Distribution Documentation of Calculations 4 1.3Hydrometer Test Calculations 1.3.1Particle Size PS = s 30 v L 980 (GS GW) ET (1.8) Where: Ps = the particle size in mm. Using riffles, take a representative sample of soil received from the field and dry it in the oven. Weigh the required quantity of dried soil, keep it in a tray and soak it with water. Soils that are non-cohesive may only require dry sieving. Determination of article size is more important in Civil Engineering, as the particle size determines the effectiveness of final product. 3.4.1.1.1 <2-mm (sieved), Air-Dry Sample. The basic method of mechanical analysis is to sieve the soil through a set of sieves of standard opening size. Grain size analysis is the determination of the size grain of particles present in a soil. An analysis of this kind express quantitatively the Wet sieving method is considered when the particle that is going to be used is already exists as wet or suspension. proportions by mass of the various sizes of particles present in the soil. 5mm, 2mm, 1mm, 630um, 315um, 160um, 80um and pan. It is necessary to predict the quality and performance of the soil sample. This because a fine grained soil consist of different sizes of particles starting from 0.075 mm to 0.0002 mm. Any particle may be tested to see if they will fall through but they shall not be pushed through. Weigh the specimen and record its weight. It is expressed as a percentage of the total dry weight. 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. 1.4 These test methods describe techniques performed manually using either a standard series of graded chart images for the comparison method or simple templates for the manual counting methods.
