You can then use these results, along with the Grading and Degree of Saturation to calculate the true line for that particular material. I'm looking for a way to avoid plotting errors and zero values in Scatter Plot. The truth is, youre unlikely to need this expression because most functions and expressions return the #NA error value if they try to evaluate one. Unit weights will increase with higher moisture contents leading up to the optimum moisture, then decrease past that point.

Describes the typical values tabulated in tables 4.1-2 and 4.9-2. The mold with the sample is then weighed and recorded, and the soil is extruded from the mold. 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. To draw the zero-air void line, the dry density is to be calculated and that is exp. We have received your request and will respond promptly.

Explains that compaction effort at given moisture content had an essential effect on the structure and engineering properties of compacted cohesive soil. For all of human history, construction projects from primitive burial mounds to modern interstate highways have removed, replaced, filled, or shaped the soil surface to accommodate pavements and structures or to make the earthwork itself a structure. At this stage, sample breakdown and coarse particle sizing are often performed concurrently. 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. Proctor test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density. ; If none of the predefined combo charts suits your needs, select the .
