NOTE: There are variations of test procedures noted in both the standard and modified test methods that are dictated by the maximum particle sizes of the soil samples. British Technology Awards sara macdonald instagram how to plot zero air void line in excel Some of the cells (random) have either zero value or error value. In the latter part of World War ll and later into the 1950s, heavier dynamic loads from larger aircraft and heavier, more frequent truck traffic were placing greater demand on pavements and soil subgrades. 3. material placed dry will collapse under high overburden. But theoretically speaking we can calculate the dry density for zero air voids. 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. Advises students to obtain rectangular aluminum foil from their instructor and measure the length and width of the foil using a ruler. 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 = All Rights Reserved. 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. Click Here to join Eng-Tips and talk with other members! 9. 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. Pressure will decrease in wind because the pressure on the stem will affect the amount of water being lost. Click OK to filter the column, which will filter the entire row. for specific gravity values of 2.5, 2.6, 2.7, 2.8. - edited When you join you get additional benefits. dry unit weight vs moisture content for the soil. We know that nearly any mechanical compactive effort will make soil denser, but which methods work best for each soil type? Some will work with limited results and others wont work at all. The weight of each specimen is used to calculate wet unit weights, and the oven-dried moistures are used to determine a dry unit weight for each point. 32 641 39 14; sekretariat@zkgkm.pl; Al.1000-lecia 2c 32-300 Olkusz; Dostosuj wygld: Menu gwne. Also, plot the 70%,80%, and 90% saturation curves. To work around this issue, use one of the following methods. What is the tolerance for compression test results of concrete, according to the standards? 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. 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. 29. how to plot zero air void line in excel. X-axis interception of the plot is reciprocal of Michaelis Constant, [-1/Km]. how to plot zero air void line in excel. When testing field densities, the dry unit weight from the density test is compared to the maximum dry weight from the laboratory Proctor to calculate a percent of compaction. Charting zeros isnt wrong, but you wont always want to display them in your Excel charts.
