It represents the relationship between water/moisture content and dry density. For standard Proctors, the hammers weigh 5.5lb (2.5kg) and drop 12in (305mm). Trade Route Japan 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. Previously, she was editor in chief for The Cobb Group, the world's largest publisher of technical journals. This ebook covers tips for creating and managing workflows, security best practices and protection of intellectual property, Cloud vs. on-premise software solutions, CAD file management, compliance, and more. 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.". When you create a Line chart in Microsoft Excel, the chart may contain a gap in a line. To truly check the curve you need to do a Particle Density and Water Absorption test on each particle size present. 2009-2021 The Constructor. Here are a few techniques that you can use to hide and manage zeros in your workbook. British Food & Drink Awards Explains that pycnometer is made of glass, with a clos-fitting ground glass stopper, so that air bubbles mas escape from the apparatus. British Export Awards Right click the line and click Format Data Series. The zero air void line doesnt intersect the curve attained on Dry density v/s Water content graph because soil can never achieve zero void condition with any kind of compaction. Pressure will decrease the greatest in light and heat because water will be lost due to evaporation. Explains how to solve systems of equations by plugging in 2, 3, 4, 5, and 6 for x.2.

Excel chart: Handling zero values that you dont want to chart. Explains that to avoid both types of error, make sure instrument is good and not faulty and that the experiment is correctly used by its operator. Once the soil is friable enough, the breakdown can continue more thoroughly. When preparing individual compaction specimens, it doesnt take much time to prepare a couple of extra in case your estimates are a bit off. if one beaker had more than another, there would be more solution to act on the meat. Go through the following steps to make a Lineweaver Burk plot in Excel. Now, lets make this work and use Excels Replace feature to replace the zero values in the example data set with the NA() function: Figure G above shows the settings and the results. Is this normal with very poorly graded clean fine sands? But this does not mean that 15% air void is equal to an 85% degree of saturation. Create a Line Chart in Excel (Easy Tutorial) In the above image, the Scatter with straight lines and markers was selected, but of course, any one will do. We examine how compaction is dependent on the moisture content, type of soil and. Zero Air Voids: Plot the zero air voids curve (100% saturation) This is called zero air void line or 100 % saturation line and it is given as: d = G w 1 + w G. We know that Se = wG. Click the paint bucket icon and change the line color. Using Microsoft Excel to find optimum moisture content Several charts show a gap between one value and another when the zero value is missing. Pressure will decrease the least in humidity because water is being added therefore adding more water thus creating more force against the sensor. Or does this invalidate the proctor curve? Explains that the experiment will be conducted at room temperature, although a more scientific method would be the use of an osmosis method. Click OK to filter the column, which will filter the entire row. 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. Posted on .

The other two charts have three data series: Vendor 1, Vendor 2 and Vendor 3. Plot the line of optimums. The zero air void line doesn't intersect the curve attained on Dry density v/s Water content graph because soil can never achieve zero void condition with any kind of compaction. Some will work with limited results and others wont work at all. In 1933, Ralph R. Proctor, a resident engineer for the Los Angeles Department of Water and Power, established a laboratory procedure to define the practical maximum density of a soil sample along with the optimum moisture content needed to achieve that density. The dry density is given by For zero air void line put na= 0 Hence. Story. 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 hypothesis tested: If light and heat, humidity, wind, and a controlled environment (where there is no affecting outside force) is applied to a stem then the water pressure will decrease due to transpiration. it knows every detail of soil characteristic, minerals, permeability, etc., but does not show the groundwater quality that might be contaminated with leachate. Analyzes how the precision of the results is evident from the fact that the r2 values obtained in the wilson plots are close to unity for all exchangers tested. Making a Lineweaver Burk plot requires data on Substrate Concentration (S) and Initial Velocity (Vo). Running five or six points of the proctor test can be physically demanding, especially with a modified Proctor using a 10lb hammer to compact five layers with 56 blows each. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. This requires some guesswork, and experience is always helpful. Explains that using a ruler, measure the dimensions (diameter and height) of each cylindrical object using an electronic balance. Dry Unit Weight Determination The entrained air is still in the material and that is why the curve will always turn before it reaches the ZAV line. how to plot zero air void line in excel - taocairo.com 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. Opines that geo-environmental study is a good method that can investigate the site. Once the dialog box appears, click on the Combo menu item in the left-side pane. We have received your request and will respond promptly. they conclude that the decrease in pressure is due to the rate of evaporation occurring simultaneously.

You can then use these results, along with the Grading and Degree of Saturation to calculate the true line for that particular material. 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. But is there a way to combine IF and IFERROR? Variability can result in points on the compaction curve above the ZAV line (S > 100%). British Manufacturing Awards To change the color of the line and the markers, execute the following steps. That concept is known today as the moisture-density relationship test, laboratory compaction characteristics of soils, or simply the standard Proctor test, and is detailed in ASTM D698 and AASHTO T 99 test methods. Explains that the hydrometer test covers the quantitative determination of the particle size distribution in a soil from coarse sand size to clay size. Explains that part a of the lab was conducteddetermining the density of water and measuring the mass of a 100 ml graduated cylinder using an electronic balance. Inviting the best and brightest to come & give the greatest talk of their lives. Coarser materials are set aside for particle size determinations and, in some cases, for adding proportionally back into the final test specimens. It has also helped in some problems with the soil, such as high sulfate content, which can schew the moisture contents. Jun 02 2022 Select Moving Average, then set the Period to (for example) 100. 6.12. Log in to TheConstructor to ask questions, answer peoples questions, write articles & connect with other people. Thanks. Heres how it works: Youll notice that the results are similar to those seen earlier in Figure B: Because these methods are so easy to apply, try deleting the zeros or formatting them first. Equation of A-line as represented in the given chart relates plasticity index and liquid limit as. How far above depends on the porosity of the material (which can be measured by water absorption). To find the dry density, divide the moist density by the percent moisture divided by 100, plus 1. Now that youre familiar with the example data, lets review a few methods for suppressing the zero values in our example charts. The data collected from this lab refutes this hypothesis because the results were unexpected. At the same time, field compaction equipment was becoming larger and more efficient, making it possible to compact soils to higher densities at lower moisture contents. If youre working with a Table object, you can skip this step because the filters are already there. Click the chart you want to change. Unit Weights and Densities of Soil - MATHalino Explains that the slope of the line of best fit is the density which should match a substance in the table. 7.5 The Zero Air Voids Line. Draw the graph between Dry Density VS water content, calculate the dry density from the compaction test results, and Zero Air void line is drawn on the graph. In this video, I will show you how to plot a dry unit weight against moisture content graph along with the zero air void line using Microsoft Excel. PDF 1. Moisture-Density Documentation of Calculations - GEOSYSTEM Software What is the tolerance for compression test results of concrete, according to the standards?
