For determination of particle size distribution of fine, coarse and all-in-aggregates by sieving.

IS : 2720 (Part 4) – 1985 – Method of test for soil (Part 4-Grain size analysis)

  • Balance
  • Sieves
  • Sieve shaker

After receiving the soil sample it is dried in air or in oven (maintained at a temperature of 600C). If clods are there in soil sample then it is broken with the help of wooden mallet.

IS: 2720 ( Part 16 ) - 1987 0.5 In reporting the result of a test or analysis made in accordance with this standard, if the final value, observed or calculated, is to be rounded off, it shall be done in accordance with IS: 2 - 1960. 2.8 Straight Edge - A steel strip about 30 cm long, 2.5 cm wide and 3 to 5 mm thick, with one bevelled edge will be suitable. 2.9 Apparatus for Extracting Samples from the Cutter - Optional. 2.10 Apparatus for Determination of IS: 2720 ( Part II )-1973. Water Content - In accordance with 3.

  1. The sample is dried to constant mass in the oven at a temperature of 1100±50C and all the sieves which are to be used in the analysis are cleaned.
  2. The oven dry sample is weighed and sieved successively on the appropriate sieves starting with largest. Each sieve is shaken for a period of not less than 2 minutes.
  3. On completion of sieving the material retained on each sieve is weighed.

Uk itunes code generator free download. The percent retained (%), Cumulative retained (%) & percent finer (%) is calculated.

Percent retained on each sieve = Weight of retained sample in each sieve / Total weight of sample

The cumulative percent retained is calculated by adding percent retained on each sieve as a cumulative procedure.

The percent finer is calculated by subtracting the cumulative percent retained from 100 percent.

The result of the sieve analysis is reported graphically on a semi log graph, taking sieve sizes on log scale and % finer in arithmetic scale. The observation is maintained in observation sheet.

  • Clean the sieves set so that no soil particles were struck in them
  • While weighing put the sieve with soil sample on the balance in a concentric position.
  • Check the electric connection of the sieve shaker before conducting the test.

For determination of the moisture content of soil by oven drying method.

  • Oven (1050C to 1100C min.)
  • Metal container
  • Balance (0.01 g accuracy)
  1. The number of the container is recorded, cleaned, dried and weighed.(W1)
  2. About 15-30 g of soil is placed in the container and the weight of soil with the sample is recorded.(W2)
  3. The can with the soil is placed in oven for 24hours maintained at a temperature 1050 to 1100C.
  4. After drying the container is removed from the oven and allowed to cool at room temperature.
  5. After cooling the soil with container is weighed.(W3)

W1=Mass of container, g

W2=Mass of container and wet soil, g

W3=Mass of container and dry soil, g

The water content of the soil is reported to two significant figures.

  • Use hand gloves while removing containers from oven after switching off.
  • The soil should be loosely placed in the bin, so as to allow easy evaporation of moisture
  • Over heating should be avoided.
  • Oven dry soil should not be kept open to the atmosphere (for cooling) as it may absorb moisture from atmosphere
  • Ensure the identification number on the base and the lid of the bin is same
