Remember that the values of water content, wet unit weight, and specific gravity are not constant throughout the soil. Plot all 4 series of data on the same Excel figure. Step-by-step solution 100% (8 ratings) for this solution Step 1 of 4 Determine the zero-air voids unit weight of the soil using the formula. None of the charts display the #N/A error values, but they still display the category label in the axis and the legend, similar to the results shown in Figure B. Unfortunately, when you remove the filter, the charts update and display the zero values. The saturated 'down' portion of the proctor curve will usually plot within this 86% & 96% zone, my experience is usually below 94% saturation. The Zero Air Voids Line . If field compaction percentages are too low or seem too high, there are some things to consider: The compaction energy from heavy equipment dissipates as the depth of the loose soil layers increases. A sample of the specimen is obtained to determine the exact moisture content by oven drying, and the process is repeated for subsequent samples. Gilson supplies a complete line of soil compaction and Proctor equipment and accessories. Question: Plot the 100% saturation (zero air voids) curve. But no matter how hard we try we cant eliminate all the air voids and get zero air voids. Stacked bar chart: Shows four stacks for the months without a zero value. If the chart doesnt display the zero in the chart or the data label but does display the series in the legend, you can remove it. Explains that double-pipe, were studied in this experiment for their feasibility for scale up. how to plot zero air void line in excel. Please let us know here why this post is inappropriate. The entrained air is still in the material and that is why the curve will always turn before it reaches the ZAV line. Start by adding a filter to the Vendor 1 column with these steps: Figure F shows the two charts based on the filtered data in column B. Copyright 1998-2023 engineering.com, Inc.

However, the proctor results seem reasonable for this material. Check that the compacted soil is the same as the laboratory proctor sample. Pakistan Power 100 Written by. However, the line chart has a serious flaw: The line is solid, and April is the same value as March distributing this chart as-is would be a serious mistake. Compaction Testing Equipment required for performing the laboratory proctor test is also straightforward and widely available. 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. If youre working with one chart, you can quickly bypass the guesswork by using a chart setting to determine how to chart zero values. After about the third point (if youre lucky and your estimates were correct), the mass of the sample will decrease as the volume of water reaches a point where it displaces soil particles in a given volume. Some will work with limited results and others wont work at all. Explains that when the stem was put into hot conditions, the rate of evaporation increased, causing a decrease in water loss by -0.00269675 kpa/min/cm2. As an experiment, plot out two additional curves, at 86% & 96% Saturation for your Specific Gravity. Table of Atterberg limit results are shown in Appendix E. The liquid limit shown is 55 %, taken at the 20 mm penetration. Choose a preferable plot design. Change the way that empty cells, null (#N/A) values, and hidden rows and columns are displayed in a chart.

The reason is that the material in the proctor test has not achieved true ZAV, there are still some voids entrained in each particle of soil and aggregate. My theory being that: 1. material placed dry of standard optimum moisture may have satisfactory performance when you proof roll - but will deteriorate over time. Step 3: Modifying Scatter Plot to Make a Lineweaver Burk Plot in Excel. Lineweaver Burk Plot and Its Components. The compaction curve theoretically does not cross this line but becomes parallel to it. We hope this article sheds enough light on making a Lineweaver Burk plot to enable you to make one. Explains that the beaches will have the same width in between years 2007 and 2008. the functions for the problem would look like p=800*0.95*t and 0=50*1.15. Other Versions of Excel: Click the Insert tab > Line Chart > Line. Excel chart: Handling zero values that you dont want to chart. Dont worry about that, but be sure to remove the filter when youre done. I cannot use the option that hides all the zero values in that tab because there are other tables some cells have zero values and I need those zeros. Please contact us with questions or to discuss your application. Step-by-Step Procedures to Make a Lineweaver Burk Plot in Excel. You can then use these results, along with the Grading and Degree of Saturation to calculate the true line for that particular material. Therefore, users may wonder how to make a Lineweaver Burk plot in Excel. Explains that they will conduct the experiment in the same place so that each test is experiencing same temperature changes. Height of cylinder = 11.6 cm Example in Original Condition: (Chart Tools) Design > Add Chart Element > Axes > Secondary . Explains the contents of a graduated cylinder, 50 ml beaker, aluminum foil and aluminum pellets, computer, distilled water, graph paper, electronic balance, ruler, and thermometer. This is the most common laboratory soil test and the basis for all engineered compacted soil placements for embankments, pavements, and structural fills. Besides, knowing the optimum moisture content gave clear guidance for whether the soils being compacted should be made drier or wetter to make everyones job easier. How not to plot zero & error values in Excel plot, Re: How not to plot zero & error values in Excel plot.

Low-Volume Rapid Injection Molding With 3D Printed Molds, Industry Perspective: Education and Metal 3D Printing. Step 2: Inserting a Scatter Plot. As we mentioned earlier, stretching the scatter plot trendline backward results in a lineweaver burk plot. It is determined by the compaction test of a soil. Explains that subsoil samples are classified as sm class (silty sand, non-plastic/non sticky) according to uscs classification. Test procedures are similar, but the laboratory compactive effort of the modified method is higher. Now to build a structure on a soil base there must be minimum air voids(to avoid settlement). If you update the data regularly, you might even enter NA() for zeros from the get-go, which will eliminate the problem altogether. Always plot the ZAV line for your lab compaction results - I've seen a very very reputable firm take a big legal hit because the field results plotted on the wrong side of the ZAV - hence the results were "suspect.". Method 1. Neither displays the zero value or the category label on the X-axis. Y-axis of the Lineweaver Burk plot that is reciprocal of velocity, [1/Vo]. The specific gravity test had been performed and is also reasonable. British Sustainability Awards 29. how to plot zero air void line in excel. However, its important to recognize that these methods arent likely to update all charts the way you want. But because the soil is a natural material and the ideal moisture content and maximum dry weight varies for each soil type, the questions of the best unit weight and ideal moisture content couldnt be answered. most of the clays contain clay and sandy material. We eliminate the air voids through compaction. Simply select that item in the legend and press Delete. Trade Route Hong Kong, Property all water coming from the surrounding environment should be drawn away. 1.7Zero Air Voids Curve The following equation is utilized when plotting a zero air voids (ZAV) curve: d= ZGS MC 100 ZGS+1 (1.8) Where: MC = the moisture content point (in percent) corresponding to a given point on the ZAV curve d = the density corresponding to MC on the ZAV curve ZGS = the user's chosen ZAV curve specic gravity 7.5 The Zero Air Voids Line. Already a Member? A previous and now closed discussion suggested a workaround using SkyDrive. You will receive a link and will create a new password via email.

The data used in this video is taken from the book titled Principles of Geotechnical Engineering 9th Edition by Braja M Das and Khaled Sobhan. Explains how they used crucible tongs to identify the mass and volume of the unknown liquid obtained from the instructor. For all of human history, construction projects from primitive burial mounds to modern interstate highways have removed, replaced, filled, or shaped the soil surface to accommodate pavements and structures or to make the earthwork itself a structure. Additionally, Excel for the web doesnt support this technique. What are the different types of handrails used in bridges. Moisture content = Weight of water / Weight of dry sample or w = [(W_(tin+soil )- W_(tin+dry soil))/(W_(tin+dry soil) - W_tin )] x 100 7.1 Average moisture content of specimen, w w = (wt + wm + wb)/3 7.2 The dry unit weight of the specimen can be calculated as follows: Let weight of empty mold = W Weight of mold and compacted soil = W1 Volume of mold, V = 1/30 ft3 (1000cc) Water content of compacted soil = w Moist Unit weight of compacted soil = W1- W = 7.3 V Dry unit weight or dry density, d = Users need to compile the raw substrate concentration and initial velocity data as depicted in the picture below. Opines that geo-environmental study is a good method that can investigate the site. In-place measured densities of the compacted fill are compared to the Proctor test results to determine the degree of soil density. The Zero air void line is obtained on a Dry Density v/s Water Content graph. I need to figure out a way not to plot those errors and zeros. When you join you get additional benefits. When you dont want to display zero values, you have a few choices for how to hide or otherwise manage those zeros. Figure 4.2 shows the result of liquid limit. If the chart doesnt chart it, most of the time it wont display the value in a data label. 1.7Zero Air Voids Curve The following equation is utilized when plotting a zero air voids (ZAV) curve: d= ZGS MC 100 ZGS+1 (1.8) Where: MC = the moisture content point (in percent) corresponding to a given point on the ZAV curve d = the density corresponding to MC on the ZAV curve ZGS = the user's chosen ZAV curve specic gravity
