Select the Change Chart Type button to launch the Change Chart Type dialog box. Weights required for the bulk sample will range from about 50lb to 100lb (23kg to 45kg) of the moist sample, depending on the test method specified. 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. This indicates that optimum moisture has been exceeded, and having another point beyond that will make it a bit easier when constructing the final compaction curve. Here are a few techniques that you can use to hide and manage zeros in your workbook. I know there are possible variations in soils but 14 lb seems like a big gap. X-axis interception of the plot is reciprocal of Michaelis Constant, [-1/Km]. That concept is known today as the moisture-density relationship test, laboratory compaction characteristics of soils, or simply the standard Proctor test, and is detailed in ASTM D698 and AASHTO T 99 test methods. Modified compaction will force more moisture into the particles and as a result will compact to about 1.5% air voids. Explains the proctor test, which determines the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density. how to plot zero air void line in excel how to plot zero air void line in excel. British Sustainability Awards Any thoughts? This is the best alternative to toggling back and forth with one data set. A) The functions for the problem would look like p=800*0.95*t and 0=50*1.15*t.
