Extract of sample

More often than not, when dealing with mechanics of soil, twenty degrees Celsius serves as the best reference temperature and it is commonly referred to as the application temperature. For reference purpose, there are some alterations that are done on the density, as well as mass of water is by 0.2% within the range of 4 and 20 degrees Celsius (Mitchell 6). Arguably, this is equal the precision test method. This way, the particle variation of the mass density over an equal range of temperature becomes insignificant. This clearly implies that Gs is utilized given that it is twenty degrees Celsius referenced. As often is the case, specific gravity is needed in the calculation of the phase relationships in many tests of engineering in the mechanics of soil. Procedure. With a view to realize the objective of this experiment, a credible procedure had to be followed strictly. In this case, approximately, 30 grams to 40 grams of dry soil was used in the experiment while ensuring that the collected sand was a dry mass of coarse and gravel sands. This way the coarse grained matter was dried on the oven before the experiment with the purpose of drying the being to accelerate the experiment and turn it practical for the experiment and instruction in class. ...
The soil was then mixed in a blender with approximately 80 grams of distilled water with the slurry being transferred into volumetric flask. The slurry was deaaired by boiling for a time period of three minutes. For the coarse-grained soils,

an equivalent 200 grams of soil was obtained and the mass obtained to 0.01 g after, which all the materials were transferred into the volumetric and covered with distilled water. Following the set procedures, a vacuum was applied to the moisture for a period of 3 minutes. It was then agitated gently with an intension of removing air. The volumetric flask was then filled with the distilled water to a level above the calibration. This was done while working with the clay soil in order to ensure clear water is obtained in the volumetric top. A sponge at the Marriott bottle type end was used for purposes of maintaining a somewhat clear interface. The gravity of water was introduced using a total head followed by placing of the volumetric alongside the plug in a cool resting position. In this regard, the equilibrium time depended on the process followed in Deairing the soil, as well as the process of testing of the soil. The volumetric was then transferred into a surface that was insulated while making sure the volumetric was in a position of storage having the stopper resting, submerged and unplugged partially. Then, the volumetric was capped off, excess water extracted with bottle water and dry rimmed with paper towel strips, and the mass determined to 0.01 g. This was given by MB+W+ST. This was done quickly and the volumetric handled with gloves to inhibit the changes int he temperature. The cap was removed and temporarily kept aside. A digital thermometer was used in measuring the temperature inside the
