The specific gravity test had been performed and is also reasonable. I know there are possible variations in soils but 14 lb seems like a big gap. 9. Its also convenient to sieve the coarse material now to reduce handling. To draw the zero-air void line, the dry density is to be calculated and that is exp. In other words, after removing this option, the charts are the same as they were in Figure A. Download Excel Workbook. If there's a chance that there could be a low value that's not 0 but you don't want plotted, consider using something like C1<1 to catch those values. 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. The zero Air Void line is obtained when there is no presence of the air in the pores of a soil mass and totally filled with the water and soil mass get saturated. Y-axis interception of the plot is reciprocal of maximum velocity, [1/Vmax]. Check that the compacted soil is the same as the laboratory proctor sample. The setting for the secondary vertical axis only affects the secondary horizontal axis. density to moisture content curve, air void and zero void line |soil mechanics | Multi Experts Tutor - YouTube 0:00 / 6:01 Soil Mechanics 1 density to moisture content curve, air void. Modified compaction will force more moisture into the particles and as a result will compact to about 1.5% air voids. Add Vertical Lines To Excel Charts Like A Pro!

Unfortunately, when you remove the filter, the charts update and display the zero values. But is there a way to combine IF and IFERROR? Zero air voids cannot be achieved with standard compaction the closest you will get is about 2% air voids. Alternatively you could group the columns if they are zero. Plus, as the material is fairly free-draining the action of compaction can allow what fines there are to be transported by 'free' water away from the sample, further influencing the ability to 'fill the voids'. In this video we graph the moisture content and dry unit weight in order to find the optimum moisture content. Explains that sieve analysis or gradation test is used to assess the particle distribution of a granular material. What it comes down to is it doesn't matter where you plot your air voids line from 0%(well above proctor) to 5%+(well below proctor), the crucial point is that the wet side of the proctor curve should be close to parallel with the air voids line. The dry density is given by For zero air void line put na= 0 Hence. If an 18in (450mm) layer (lift) of soil cannot be compacted to the required percentage, try reducing the lift thickness to 10in or 12in (250mm or 300mm) or increase the number of passes. Defines atterberg limit as the certain water content which is exhibit in soils at a given properties. Explains that the hydrometer test covers the quantitative determination of the particle size distribution in a soil from coarse sand size to clay size. The entrained air is still in the material and that is why the curve will always turn before it reaches the ZAV line. I enjoy solving problems, finding workable solutions, and most of the part I really like to take on challenges. Now plot the water content in column 6 and the dry unit weight in column 7. Explains that subsoil samples are classified as sm class (silty sand, non-plastic/non sticky) according to uscs classification. Recommends investigating the groundwater contamination, referring to the leachate leakage.
