(2003) Soil Mechanics and Foundation Engineering. Enter a title for the chart and the desired chart background color. Organic soils are distinguished by a dark-brown to black color, an organic odor, and visible fibrous matter. That is CL-ML. Select the data that you want to use and click "Insert" on the main toolbar. Divide the graph into zones based on the strain levels. Label the sections with the four words or phrases you want to focus on. Begin by obtaining soil plastisity index (SPI) data and arranging it in columns. The first column should contain the values for the plasticity index, and the second column should contain labels for each measured value. When the pie chart is drawn, the slice of pie for Group A will have an angle of 196.36; as such, it will represent just over half of the full circle. The plasticity chart has a shaded area; soils that plot in this area (above the A-line with PI values between 4 and 7) are silty clay and are given the dual symbol CL-ML. Label the y-axis with the characteristics of the soil sample in question (e.g. Fully recover from injury & improve performance, Over the past decade, our clinical team has successfully treated over 2,000 clients with concussions. This Privacy Policy document contains types of information that is collected and If more than 50% percent of soil passes through 75micron sieve, then it is classified as fine-grained soil.

These letters are: W Well graded L Low plasticity (wL<35%) P Poorly graded I Intermediate (35
