Density and specific gravity lab report answers

Iv) Entrapped air can be removed by heating the density bottle on a water bath or a sand bath. Add water to fill the bottle to about half. Iii) Cover the soil with air-free distilled water from the glass wash bottle and leave for a period of 2 to 3hrs. The bottles and contents together with the stopper should be weighed to the nearest 0.001g (W 2). Ii) The sub-sample, which had been oven-dried should be transferred to the density bottle directly from the desiccator in which it was cooled. I) The density bottle along with the stopper, should be dried at a temperature of 105 to 110 oC, cooled in the desiccator and weighed to the nearest 0.001g (W 1).

Procedure to Determine the Specific Gravity of Fine-Grained Soil A 5 to 10g sub-sample should be obtained by riffling and oven-dried at a temperature of 105 to 110 oC. The soil sample (50g) should if necessary be ground to pass through a 2mm IS Sieve. V) Weighing balance, with an accuracy of 0.001g Iv) Oven, capable of maintaining a temperature of 105 to 110 oC Ii) Constant temperature water bath (27.0 + 0.2 oC)

I) Two density bottles of approximately 50ml capacity along with stoppers Of a material at a standard temperature to the weight in air of an equal volume of distilled water at the same stated temperature. Specific gravity is the ratio of the weight in air of a given volume This test is done to determine the specific gravity of fine-grained soil by density bottle method as per IS: 2720 (Part III/Sec 1) вЂ“ 1980.
