Is Code 2720 Part 8 Free Download
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.
- 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.
- 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.
- 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)
- The number of the container is recorded, cleaned, dried and weighed.(W1)
- About 15-30 g of soil is placed in the container and the weight of soil with the sample is recorded.(W2)
- The can with the soil is placed in oven for 24hours maintained at a temperature 1050 to 1100C.
- After drying the container is removed from the oven and allowed to cool at room temperature.
- 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
