Always plot the ZAV line for your lab compaction results - I've seen a very very reputable firm take a big legal hit because the field results plotted on the wrong side of the ZAV - hence the results were "suspect.". Water is added incrementally and mixed thoroughly to increase the individual moisture contents for each specimen by about 2%. Explains that a particle size distribution was obtained by the combination of dry sieve test and hydrometer test (bs1377-2:1990). Note that zero air void line cant be achieved in real life. Select the data set. 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. My self, Maruf Islam, an engineer and Excel & VBA Content developer on Exceldemy. This results in higher maximum soil densities at lower optimum moisture contents. Learn methods and guidelines for using stereolithography (SLA) 3D printed molds in the injection molding process to lower costs and lead time. Click anywhere in the chart. 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. British Interior Design Awards When the required densities are hard to reach in the field, the moisture content should be compared to the optimum moisture content from the lab tests. I cannot use the option that hides all the zero values in that tab because there are other tables some cells have zero values and I need those zeros.

For each Proctor point, the operator compacts the specimen into the pre-weighed soil compaction mold assembly in three to five layers (lifts) according to the method required. The ZAV will always be above the proctor curve. In-place measured densities of the compacted fill are compared to the Proctor test results to determine the degree of soil density. Explains that they are planning an experiment to investigate how ph affects the ability of raw meat to absorb water. Compaction Testing Equipment required for performing the laboratory proctor test is also straightforward and widely available. In simple terms, densities were too low, and optimum moistures were too high for these increased loadings. In other words, after removing this option, the charts are the same as they were in Figure A. 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. Workaround. 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. how to plot zero air void line in excel. If you have a 'fine sand' this suggests that a significant part of the material under analysis will be single sized and be relatively free draining.
