How far above depends on the porosity of the material (which can be measured by water absorption). The modified Proctor method uses a 10lb hammer with 18in (457mm) drop height for compaction. Sample calculations must be shown. The saturation curve, or zero air voids curve, is a plot of soil density vs moisture at a theoretical 100% saturation level (zero air voids). It is determined by the compaction test of a soil. To change the color of the line and the markers, execute the following steps. 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. If you work through the instructions with our demonstration workbook file, undo each solution before you start the next. 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. You will receive a link and will create a new password via email. 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. In a perfect world if you knew the exact figure for the entrained air voids, say 2.36% e.g., then your plotted voids line would go through each wet point of the proctor curve, however, it still wont be precise because the proctor curve is simply a line of best fit through four or more data points which each have their own vagaries of precision. Explains how they calculated the masses for the three unknown samples by subtracting the sample mass from the initial mass of the dry graduated cylinder.

If so, on the Chart Design ribbon, choose Select Data (or right-click on the line and choose Select Data) and look for the option where you can tell Excel how to treat Hidden and Empty Cells. Now that youre familiar with the example data, lets review a few methods for suppressing the zero values in our example charts. Plot the line of optimums. 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. In the above image, the Scatter with straight lines and markers was selected, but of course, any one will do. But theoretically speaking we can calculate the dry density for zero air voids. What is the tolerance for compression test results of concrete, according to the standards? (Excel for the web doesnt allow access to this setting). In this article, we demonstrate step-by-step procedures to make a Lineweaver Burk plot in Excel. 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. they plot the compaction curve i.e. Explains that the experiment will be conducted at room temperature, although a more scientific method would be the use of an osmosis method. On Exceldemy I write articles discussing various way outs of Microsoft Excel's stuck ons. Sample Call breaded ham and cheese breakfast bars school| ap human geography frq 2018 student samples or metrotown food court hours Tips: The same technique can be used to plot a median For this, use the MEDIAN function instead of AVERAGE. If you turn on data labels, you will see the zero listed. Any soil that is compacted will not be fully saturated - hence, as you are plotting dry unit weights, you must have air in many of the voids. Some will work with limited results and others wont work at all. If youve been staying away from the gym lately, you might want to call in a favor or two, or better yet, consider a. Explains the classification table from british soil classification system (bscs). Explains that the slope of the line of best fit is the density which should match a substance in the table. Explains that compaction effort at given moisture content had an essential effect on the structure and engineering properties of compacted cohesive soil. A) The functions for the problem would look like p=800*0.95*t and 0=50*1.15*t. P represents the pine, After calculating all the values, we put it in a graph to compare the density, mass, and volume by using. Create a helper column and add your date and time so it's in one value. Several charts show a gap between one value and another when the zero value is missing. Explains that each of the 5 buffer solutions should have the same volume of 50ml and same concentration. The compaction curve theoretically does not cross this line but becomes parallel to it. 32 641 39 14; sekretariat@zkgkm.pl; Al.1000-lecia 2c 32-300 Olkusz; Dostosuj wygld: Menu gwne.

The modified Proctor test was introduced in 1958 as ASTM D1557 and AASHTO T 180 to help with these applications at higher loads. For each Proctor point, the operator compacts the specimen into the pre-weighed soil compaction mold assembly in three to five layers (lifts) according to the method required. - edited We reviewed their content and use your feedback to keep the quality high. Alternatively you could group the columns if they are zero. Recall that: The reader is encouraged to carefully read and understand the ASTM or AASHTO test methods. Select the dataset and click on the 'Insert' tab. These data points should not be thrown out. This problem has been solved! The most permanent fix for hiding zeros is to replace literal zero values with the NA() function using Excels Find and Replace feature. 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. Line chart: Drops to zero on the X-axis. IP = 0.73 (WL - 20). Result: 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.". values by using buffers set at PH 1, 3, 5, 7, 9. 1. Once the soil is friable enough, the breakdown can continue more thoroughly. 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.
