Describes the typical values tabulated in tables 4.1-2 and 4.9-2. The saturated 'down' portion of the proctor curve will usually plot within this 86% & 96% zone, my experience is usually below 94% saturation. The entrained air is still in the material and that is why the curve will always turn before it reaches the ZAV line. Small voids can be manually filled with excess samples. Wet density(gm /cc) After compaction, the collar is removed, and excess soil is carefully trimmed with a straightedge tool, so the compacted soil is flush with the top of the mold. Explains that when the stem was put into hot conditions, the rate of evaporation increased, causing a decrease in water loss by -0.00269675 kpa/min/cm2. British Healthcare Awards 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. Workaround. On the other hand, there will be times when you wont want to draw attention to a zero. they conclude that the decrease in pressure is due to the rate of evaporation occurring simultaneously. To do so manually, enter =NA(). The reason is that the material in the proctor test has not achieved true ZAV, there are still some voids entrained in each particle of soil and aggregate. Some of the cells (random) have either zero value or error value. For standard Proctors, the hammers weigh 5.5lb (2.5kg) and drop 12in (305mm). It doesn't look like you need a secondary horizontal axis in this case so you can turn it on, set its crossing point to 0, and then hide the labels and tick marks. Opines that the study focused on the mineral and soil characteristic to investigate a site, and less focus on organic contamination that might happen to the unsanitary landfill. 4. Additionally, Excel for the web doesnt support this technique. 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. Also, I can't use any macro. Explains that the amount of water absorbed by the diced steak by process of osmosis is dependent on the mass before and after marination. 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.
