Sravan Muguda Geotechnical Engineer shravanmv gmail. These technical experts represent producers, users, consumers, government and academia from over countries. To know the behaviour of soils and its suitability in the site, we need to tests the soils in the field and as well as in the laboratory. Wherever you may test the soils it is necessary to follow a standard procedures of testing Soil Characterization: Particles of rock which passes through 75mm and retain on 4.

Asmt through 75mm and retained on 19mm sieves. Passing through 19mm and retained 4. Particles of rock which passes through 4. Further it is classified as: Passing ast m sieve and 75 m sieves. Soil passing through 75 m sieve that is non plastic or slightly plastic that will exhibit no or little strength when air dry.

Soil passing through 75 m sieve that can exhibit plasticity putty like structure within a range of water contents and exhibits strength with air dry. Soil composed of vegetable tissues in various aetm of decomposition usually organic odour, a astn brown or black color, a spongy consistency, and a texture varying from fibrous to amorphous. The lid used should be removed while keeping in the oven, if it is used.

Minimum mass moist material should be representative of the total sample and it depends upon the maximum particle size. Atleast minimum capacity of ml. Entrapped Satm Removal Apparatus. There are two methods to find out the specific gravity of the specimen Method A: Procedure for the Moist Specimens.

This is preferred method. Procedure for the Oven-Dry Specimens. Significance of the test: The pycnometer should be calibrated with respect to temperature, top meniscus of water and the water should be properly de-aired. If Method A is being followed, recommended mass of specimen should be taken for conducting the experiment.

K is obtained from referring to the table 2, Pg 4,D This particular ASTM code explains the procedure for preparing the soils for the tests.

Active Risk Management

There are two ways of preparing the sample. C2217 choice of the preparation method depends on the properties of the soil. It provides that the sample shall be kept at a moisture content equal or greater than the natural water content. Mortar and Rubber-Covered Pestle 3.

Filter Funnel or Candles 7. Dry the qstm sample as received from the field to the room temperature or keeping in the oven at a temperature of C. Break Up aatm aggregations of the particles by a suitable device 3.

Select a representative sample by the method of quartering. The amount of the representative sample should be enough to perform the required tests. Separate the sample as the particles retained and particles passing through a No. Check for the hygroscopic moisture. The material retained on the No. The material retained on No. While the material passing through the No. Above water is decanted or pipetted out and dried at C and added to the material passing No. In some cases Buchner Funnels with filter paper is also used for removal of water.

Respective samples are taken to conduct the required tests. Particle Size analysis gives a clear asstm of the distribution of the particles of different sizes in the r2217. ASTM D gives a guidelines for particle size analysis. This is the method covers the quantitative determination of the distribution of the particles. Water Bath or a constant temperature room 8. By placing the palm on top of the cylinder turn it upside down for about a min.

Take hydrometer readings at 2,5,15,30,60 and min. Note the temperature each time. Plastic Limit wp is defined as the maximum water content at which the soil can be rolled into a thread of approximately 3mm in diameter without breaking. Liquid limit device 2. Flat Aztm Tool 8. Water Content Containers The soil is then taken into the cup such that the surface d22217 parallel to the horizontal.

Then using a grooving tool the soil is taken out such that the grooving tool is always perpendicular to the cup at asfm time contact. This is done for different blows ranging between 15 to 35 blows. It is important to maintain a uniform rolling pressure; do not reduce the pressure as the thread diameter approaches 3mm. Repeat until the thread shears both longitudinally and transversely when it has been rolled to about 3mm diameter, as gauged by a rod.

ASTM D Standard

Repeat on the duplicate sample. The TORVANE is a hand-held vane shear device for rapid determination of shear strength in cohesive soils either in the laboratory or the field. It may also be used on the ends of thin wall or split spoon samples and soil chunks removed from test pits, etc. Pointer will indicate maximum shear value until manually reset.

The torque is then converted to a unit shearing resistance of the cylindrical surface area. The torque is measured by a calibrated torque spring or torque transducer that is attached directly to the vane. Insert the blade of the vane into the sample atleast two times the height of the vane blade to ensure that the ast is completely embedded in the sample. Take the initial reading. Hold the sample firmly to avoid any rotation of sample. Take reading after the sample has failed.

To determine the remolded shear strength of the soil, rotate the vane blade rapidly 5 to 10 times revolutions. Then the sample is sheared with the same initial reading. Remember me on this computer.
