Virtual laboratory instructional video for the "Specific Gravity of Fine Aggregate." Geotechnical Engineering (CEG3011) course at the University of North Florida
The pycnometer is similar to a flask that is used to measure exactly volumes of liquids, indicated on the surface by a gauging line. I don't know how to say it in English, but in Spanish I know it as "Matraz Aforado"
Hi is that the results of the specific gravity that show in the screen, is that the specific gravity or not? Because in my calculations different from yours
The values of specific gravities are not shown in this video, but the values needed to calculate it are! The procedures and equations needed to calculate the Specific Gravity of solid can be found in ASTM D845-14.
Are you referring to the pycnometer (or flask)? Iif you are following ASTM D854-14, then the minimum acceptable pycnometer volume should be 250 mL. The ASTM also states "the volume of the pycnometer must be 2 to 3 times greater than the volume of soil-water mixture." Theoretically, however, you could use any volume of flask, as long as it is able to hold the necessary vacuum to de-air (saturate) the sample.
Great video, I'm recently getting into soils mechanic and your content proved useful. Keep it up!

Good teacher 👌🏻
Hi I am running a small plant and interested in a simple way to measure the density of my slurry

❤️❤️❤️❤️
you can use other sizes like 100 mm or have to 500 mm?
