I enjoy solving problems, finding workable solutions, and most of the part I really like to take on challenges. To begin, you might try removing zero values altogether if its a literal zero and not the result of a formula. IP = 0.73 (WL - 20). The zero air void line doesnt intersect the curve attained on Dry density v/s Water content graph because soil can never achieve zero void condition with any kind of compaction. Explains that sieve analysis or gradation test is used to assess the particle distribution of a granular material. Four or five specimens are prepared for the compaction points with increasing moisture content that will bracket the estimated optimum water content. It has long been known that the moisture content of soils, particularly cohesive soils, has a direct impact on how efficiently they can be compacted by construction equipment. Unfortunately, this simplest approach doesnt always work as expected: If you removed zero values in the sheet during this phase, re-enter them before continuing to our next example.

Explains that double-pipe, were studied in this experiment for their feasibility for scale up. 4. Cause. 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. The Zero Air Voids Line . 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. If you update the data regularly, you might even enter NA() for zeros from the get-go, which will eliminate the problem altogether. Basic weight volume relationships are used to develop the equation for the ZAV line. Explains that the zero air voids (zav) line is the combination of moisture and density that produce complete saturation of the soil. Explains that the duration of water pressure exposed increases on the subsoil, causing liquefaction potential, and increasing permeability. The purpose of this lab was to learn about transpiration and to determine which conditions would decrease water loss in a plant the fastest. Russia Power 100 Calculate the zero-air-void unit weights for a soil with Gs = 2.6 at moisture contents of 5, 10, 15, 20, and 25%.

Create a helper column and add your date and time so it's in one value. A sample of the specimen is obtained to determine the exact moisture content by oven drying, and the process is repeated for subsequent samples. the highest discharge flow rate reached up to 3 l/s. Gilson supplies a complete line of soil compaction and Proctor equipment and accessories. Plus, as the material is fairly free-draining the action of compaction can allow what fines there are to be transported by 'free' water away from the sample, further influencing the ability to 'fill the voids'. 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. Prepared soil specimens with progressively higher moisture contents are compacted into molds with known volumes and weighed, then their unit weights are calculated in pounds per cubic foot or kilograms per cubic meter. When performing a field density test, the dry unit weight is compared to the maximum dry weight of the Proctor tests to calculate a percent of compaction. I need to figure out a way not to plot those errors and zeros. Explains that soils consisting of clay or silts size particles are rarely encountered. In the above image, the Scatter with straight lines and markers was selected, but of course, any one will do. For standard Proctors, the hammers weigh 5.5lb (2.5kg) and drop 12in (305mm). The standard and modified Proctor test procedures are straightforward. Compute the degree of saturation at the optimum point for data in column A. d. Plot the 100% saturation (zero air voids) curve.
