The modified Proctor is used today concurrently with the standard Proctor. What it comes down to is it doesn't matter where you plot your air voids line from 0%(well above proctor) to 5%+(well below proctor), the crucial point is that the wet side of the proctor curve should be close to parallel with the air voids line. You will only get dry densities close to the zero air void line if you can pack all the voids, however if as described you have a fine sand, there may be insufficient fines to achieve this. Written by. To change the color of the line and the markers, execute the following steps. Maximum Velocity of the enzyme-inhibited reaction, Vmax. Explains that the data is accounted for in the line. The results are plotted with moisture on the horizontal axis and dry unit weight on the vertical to form a curve that defines maximum dry density and optimum moisture content. Plot all 4 series of data on the same Excel figure. Alternatively you could group the columns if they are zero. Explains that soils consisting of clay or silts size particles are rarely encountered.

It has also helped in some problems with the soil, such as high sulfate content, which can schew the moisture contents. 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. But asI stated the ZAV curve is much higher than the plotted proctor curve. Explains that the zero air voids (zav) line is the combination of moisture and density that produce complete saturation of the soil. 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.

Zero Air Voids: Plot the zero air voids curve (100% saturation) for specific gravity values of 2.5, 2.6, 2.7, 2.8. Please let us know here why this post is inappropriate. 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. The compaction curve theoretically does not cross this line but becomes parallel to it. Country how to plot zero air void line in excel how to plot zero air void line in excel. 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. Story. Most importantly, how does the maximum soil density that we find in our laboratory tests relate to the soil densities we find in the field? British Sports Awards If you dont select the Match Entire Cell Contents option in step six, Excel will change the values 40, 404 and so on. Heres how: The zero values still exist you can see them in the Formula bar. British Charity Awards The purpose of this lab was to learn about transpiration and to determine which conditions would decrease water loss in a plant the fastest. Small voids can be manually filled with excess samples. Explains that since s = 1 when the saturation is equal to 100 percent, the relationship: gsw=e can be substituted into the above equation to yield the final equation for the zav line. 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. 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 = Please enter your email address.
