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. To truly check the curve you need to do a Particle Density and Water Absorption test on each particle size present. Trade Route Hong Kong, Property You should be somewhere around 90 percent saturation. 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. Explains that at least 5 of these tests are usually performed with different amounts of water. 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.". The following describes the Lineweaver Burk plots components. they conclude that the decrease in pressure is due to the rate of evaporation occurring simultaneously. If you dont select the Match Entire Cell Contents option in step six, Excel will change the values 40, 404 and so on. Check that the compacted soil is the same as the laboratory proctor sample. On the other hand, there will be times when you wont want to draw attention to a zero. c. Height of rammer fall = 30 cm d.

The modified Proctor is used today concurrently with the standard Proctor. This will appear that the value is skipped but the preceding and following data points will be joined by the series line. Zero Air Voids: Plot the zero air voids curve (100% saturation) show more content, The coordinates of the peak of the curve give the maximum dry density and the optimum moisture content. The steps are similar to what Susan Harkins describes in the following tutorial. When you join you get additional benefits. Transpiration is the process of water traveling through the plant to allow nutrients in and to cool the plant. The containers can be sealed metal cans, but heavy-duty zip-closure bags work well for this step. 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. Play with the value of Period to see if you get something you like. Table of Atterberg limit results are shown in Appendix E. The liquid limit shown is 55 %, taken at the 20 mm penetration. how to plot zero air void line in excel. Line chart: Drops to zero on the X-axis. Notes: The Lineweaver Burk Plot may have a different depiction depending on the intensity of its components. But no matter how hard we try we cant eliminate all the air voids and get zero air voids. This setup simplifies all the examples well be reviewing in this guide: Right now, the charts display zero values by default in each chart type: Your results may vary, depending on Excels default settings and theme colors. The weight of the specimens should be about 5lb (2.3kg) each for 4in (102mm) molds and 13lb (5.9kg) for 6in (152mm) molds to ensure enough compacted volume to properly fill the molds. 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 9. All the wet points should fall on this line. The degree of saturation is a variable, (both from material to material and at different %compaction in the same material), and as such is not a reliable way of checking a proctor curve. Opines that the exchangers studied are the best selection for scale up. Depending on how much charting you do, you might find more than one of these methods helpful. 2. material placed dry of optimum will swell under low overburden. Explains how to plot the zero air voids curve (zero-air-void unit weight vs moisture content) on the same plot as the compaction curve. Wet density(gm /cc) Home.
