If you update the data regularly, you might even enter NA() for zeros from the get-go, which will eliminate the problem altogether. Pressure will decrease the greatest in light and heat because water will be lost due to evaporation. This results in higher maximum soil densities at lower optimum moisture contents. For any soil , for a given amount of compactive effort, the density obtained depends on the moisture content. These data points should not be thrown out. Step 2: Inserting a Scatter Plot. (c) Determine the optimum water content and maximum dry unit weight of the soil from the curve (d(max) and wopt). The IF() function returns #N/A if the result is zero (Figure I): The examples contrived, but dont let that bother you. Explains the purpose of this lab was to determine the density of distilled water, aluminum, and to use density calculations to identify a mystery material. 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. Suppose youre working with the results of formulas that might return zero instead of an error value as shown in Figure G. In that case, you can use an IF() function to return the #N/A error using the following syntax: The MIN() function returns the minimum value for each month. The data used in this video is taken from the book titled Principles of Geotechnical Engineering 9th Edition by Braja M Das and Khaled Sobhan. Four or five specimens are prepared for the compaction points with increasing moisture content that will bracket the estimated optimum water content. It is determined by the compaction test of a soil. Explains that they are planning an experiment to investigate how ph affects the ability of raw meat to absorb water.

Call breaded ham and cheese breakfast bars school| ap human geography frq 2018 student samples or metrotown food court hours But no matter how hard we try we cant eliminate all the air voids and get zero air voids. Thus draw a graph for dry unit weight and moisture content where the peak represents OMC(optimal moisture content) while there is also a straight line representing soil which is 100% saturated with zero air voids. Height of cylinder = 11.6 cm Explains that the duration of water pressure exposed increases on the subsoil, causing liquefaction potential, and increasing permeability. Explains the falling head permeability test, which uses water capability to pass through a sample and determines the diameter of the standpipe. 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. On the other hand, there will be times when you wont want to draw attention to a zero. California Bearing Ratio Test: CBR Values & Why They Matter, Construction Materials Testing Certifications: an Overall Compilation. Running five or six points of the proctor test can be physically demanding, especially with a modified Proctor using a 10lb hammer to compact five layers with 56 blows each. Figure 4.2 shows the result of liquid limit. Now that youre familiar with the example data, lets review a few methods for suppressing the zero values in our example charts. If you have a single data series, you can filter out the zero values and chart the results. The mold with the sample is then weighed and recorded, and the soil is extruded from the mold. Draw the graph between Dry Density VS water content, calculate the dry density from the compaction test results, and Zero Air void . Find the reciprocals of both raw data (i.e., Highlight the reciprocals, leaving the first non-value entries, and then go to, Click on a point on the plot, then right-click on it. This issue may occur when the data range for the Line chart contains a blank cell. If an 18in (450mm) layer (lift) of soil cannot be compacted to the required percentage, try reducing the lift thickness to 10in or 12in (250mm or 300mm) or increase the number of passes. British Property Awards Back in the lab, processing of the samples begins with gradual air-drying to the desired moisture, usually around 10% or more below the anticipated optimum moisture. Manipulating the characteristics of soils by compaction naturally raises some questions. To calculate the density of an irregular solid, weigh and record the solid, measure the volume of water you intend to use, then carefully, 4. Zero air void line is the line that shows the relationship between the water content and the dry unit weight of the soil with a 100% degree of saturation or at zero void is called the zero air void line or 100% degree of saturation line.
