In-place measured densities of the compacted fill are compared to the Proctor test results to determine the degree of soil density. 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. So this is consistent with my plot. If you work through the instructions with our demonstration workbook file, undo each solution before you start the next. Sometimes the compacted soils had passing density tests based on standard Proctor values but were still deflecting too much under load to carry the increased forces. Read next: The 8 best alternatives to Microsoft Project (Free & Paid) (TechRepublic). Several charts show a gap between one value and another when the zero value is missing. In the Display Options For This Worksheet section, choose the right sheet from the drop-down menu. Rather than look at the "height" of the zav above the max dry density, consider the position of the zav to the right of the max dry density/optimum moisture content. Back in the lab, processing of the samples begins with gradual air-drying to the desired moisture, usually around 10% or more below the anticipated optimum moisture. ; Adding a target line or benchmark line in your graph is even simpler. The ZAV will always be above the proctor curve. On the Data tab, click Filter in the Sort & Filter group. 2. material placed dry of optimum will swell under low overburden. If youre working with a Table object, you can skip this step because the filters are already there. The entrained air is still in the material and that is why the curve will always turn before it reaches the ZAV line. Set aside your plus-size material as you break down the bulk sample.

Depending on how much charting you do, you might find more than one of these methods helpful. The wet side of the curve is parallel to the plotted proctor curve and the curve does not cross to the right of the proctor curve. Explains that sieve analysis or gradation test is used to assess the particle distribution of a granular material. 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. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. As a general rule you can use a 2% air voids line and it should come near enough to your proctor curve to be reliable for visual purposes. 3. material placed dry will collapse under high overburden. The main principle of the test is compaction process by which the bulk density of an aggregate of matter is increased by driving out air. 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.

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. Once the soil is friable enough, the breakdown can continue more thoroughly. Opines that a study on groundwater contamination could focus on ph, and organic contaminant brought by leachate. Explains that a particle size distribution was obtained by the combination of dry sieve test and hydrometer test (bs1377-2:1990). You will receive a link and will create a new password via email. Find out more about the Microsoft MVP Award Program. Explains that the data obtained in this experiment are consistent with this theory. These data points should not be thrown out. China Power 100 Variability can result in points on the compaction curve above the ZAV line (S > 100%). 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. 9. The moist density, or unit weight, of each compacted specimen is computed by dividing the mass of the soil (minus the mold assembly) by the volume of the mold.

The results are plotted on a graph as dry unit weight vs. moisture content and will show the curvilinear relationship that allows the maximum dry weight and optimum moisture for each type of soil to be established. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.The Eng-Tips staff will check this out and take appropriate action. 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. Additionally, Excel for the web doesnt support this technique. Figure A shows the data and initial charts that well update throughout this article. Zero air voids cannot be achieved with standard compaction the closest you will get is about 2% air voids. The zero-air void curve is non-linear. By Any thoughts? 2022. czerwiec. On the Chart Design tab of the ribbon, click Add Chart Element > Trendline > More Trendline Options. the effect of clay would be predominant. 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.". Now plot the water content in column 6 and the dry unit weight in column 7. Already a Member? The containers can be sealed metal cans, but heavy-duty zip-closure bags work well for this step. First off, ZAV means NO AIR - the material is all water and soil particles. In theory, if the two curves intersect, there has been an error in testing, calculating, or plotting the results. We hope this article sheds enough light on making a Lineweaver Burk plot to enable you to make one. 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. Remember that the values of water content, wet . In other words, after removing this option, the charts are the same as they were in Figure A. Michaelis Constant, Km is the measurement of enzyme affinity. For any soil , for a given amount of compactive effort, the density obtained depends on the moisture content. Any thoughts on why the ZAV is not close to the curve? Explains the plasticity index, which measures the amount of water that must be added to change a soil from plastic limit to liquid limit. Experts are tested by Chegg as specialists in their subject area. Charting zeros isnt wrong, but you wont always want to display them in your Excel charts. 1. Also, I can't use any macro. woofar - maybe I'm not seeing your point - but who cares about the entrained air (. X-axis interception of the plot is reciprocal of Michaelis Constant, [-1/Km]. a. Cylinder diameter = 10.2 cm b. 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. Automatic/mechanical compactors are also available to make this process easier. Zero Air voids means the soil is Completely saturated hence S = 1 which becomes, w*G = e. ( For each water content as specified in the problem) Find this value of e. Substitute the void ratio value in the equation Dryunitweight = (G* Unit weight of water)/ (1+e) Find the dry unit weight for different void ratios. It is non -linear function of void ratio. Answer (1 of 2): It means the soil is fully saturated, with the air is not present in the pores of the soil mass. how to plot zero air void line in excel. Basically a soil particle has three layers; the first layer is of air, 2nd water and 3rd is of solids. Y-axis interception of the plot is reciprocal of maximum velocity, [1/Vmax]. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Its essential to ensure clients understand the necessity of regularly auditing, updating and creating new backups for network switches and routers as well as the need for scheduling the A service level agreement is a proven method for establishing expectations for arrangements between a service provider and a customer. The liquid limit of 55 % shows the soil has a high plasticity and demand of water to achieve a liquid state. 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. You should be able to determine the percent saturation at the top of the curve and then determine whether this is abnormal or not. SLAs involve identifying standards for availability and uptime, problem response/resolution times, service quality, performance metrics and other operational concepts. The compaction curve theoretically does not cross this line but becomes parallel to it. Its also convenient to sieve the coarse material now to reduce handling. For standard Proctors, the hammers weigh 5.5lb (2.5kg) and drop 12in (305mm). Full 100% saturation. 123Helpme.com.
