Question: For the data given below (Gs = 2.64): Plot the compaction curves (yd vs w) Establish the maximum dry density and optimum moisture content for each test. The weight of each specimen is used to calculate wet unit weights, and the oven-dried moistures are used to determine a dry unit weight for each point. for specific gravity values of 2.5, 2.6, 2.7, 2.8. Zero air void line is the line that shows the relationship between the water content and the dry unit weight of the soil with a 100% degree of saturation or at zero void is called the zero air void line or 100% degree of saturation line. This will appear that the value is skipped but the preceding and following data points will be joined by the series line. If you update the data regularly, you might even enter NA() for zeros from the get-go, which will eliminate the problem altogether. Dubai Power 100 Accentuate the zero line in a chart. Zero Air Voids: Plot the zero air voids curve (100% saturation) The Zero air void line is obtained on a Dry Density v/s Water Content graph. It has long been known that the moisture content of soils, particularly cohesive soils, has a direct impact on how efficiently they can be compacted by construction equipment. Proctor test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density. You can do this by simply closing the file and reopening it without saving.

Now that youre familiar with the example data, lets review a few methods for suppressing the zero values in our example charts. To do so manually, enter =NA(). Making a Lineweaver Burk plot requires data on Substrate Concentration (S) and Initial Velocity (Vo). The zero air voids (ZAV) line is the combination of moisture and density that produce complete saturation of the soil or the d obtained when there is no air in the void spaces. Here, the term G s is specific gravity of soil, g w specific weight and w is water content.
Display empty cells, null (#N/A) values, and hidden worksheet data in a The specific gravity test had been performed and is also reasonable. If the field moisture content of the soil differs from the laboratory optimum moisture by more than 2% or 3%, it becomes more difficult to compact the material to the required density.

Advises that hectic and rough handling of hydrometer should be avoided because it will affect the reading due to the mixing of particles in cylinder. Plot the 100% saturation (zero air voids) curve. To draw the zero-air void line, the dry density is to be calculated and that is expressed as below. Experience and experimentation have taught us that compacting the soils we place makes the installation more permanent, along with some other advantages. Thus draw a graph for dry unit weight and moisture content where the peak represents OMC(optimal moisture content) while there is also a straight line representing soil which is 100% saturated with zero air voids.
