Figure 8.
The graph illustrates the relationship between strain, measured in percent, on the X-axis and unconfined compressive strength, measured in kilonewtons per square metre, on the Y-axis. The data points are plotted for various conditions, represented by different markers, circles indicate no cement, while crosses, triangles, and squares represent 14 day and 21 day strength tests with cement content of 1 percent, 2 percent, and 3 percent. Lines connect the markers to depict trends in strength with increasing strain values, which range from 0 to 2 percent on the X-axis and 0 to 230 kilonewtons per square metre on the Y-axis. The graph includes a legend identifying the conditions, with no additional annotations or grid lines visible.The stress–strain curves of uncemented kaolin and lightly cemented kaolin with different cement content and curing times at 1.5wL for vertically cut specimens
