Users need to compile the raw substrate concentration and initial velocity data as depicted in the picture below. I am sure this has been covered above, but I would just like to add my own opinion to this. The results are plotted with moisture on the horizontal axis and dry unit weight on the vertical to form a curve that defines maximum dry density and optimum moisture content. Explains how they calculated the masses for the three unknown samples by subtracting the sample mass from the initial mass of the dry graduated cylinder. Youll still see the category label on the X-axis, but Excel wont chart the actual zero. Sometimes the compacted soils had passing density tests based on standard Proctor values but were still deflecting too much under load to carry the increased forces. density to moisture content curve, air void and zero void line |soil mechanics | Multi Experts Tutor - YouTube 0:00 / 6:01 Soil Mechanics 1 density to moisture content curve, air void.

A previous and now closed discussion suggested a workaround using SkyDrive. 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. Here, the term G s is specific gravity of soil, g w specific weight and w is water content. Remember that the values of water content, wet unit weight, and specific gravity are not constant throughout the soil. Excel for the web supports most of these techniques. In 1933, Ralph R.
