Figure 2.
The scatter plot presents the relationship between minimum cement content, labelled as e c, measured in percent on the Y-axis, and liquid limit, labelled as w L, measured in percent on the X-axis. The Y-axis ranges from 0 to 9 percent in increments of 1, while the X-axis ranges from 20 to 120 percent in increments of 10. Data points represented by hollow squares depict the correlation, following a curved trend line. The equation of the trend line is y equal 0.0012 x squared minus 0.1059 x plus 4.1437, with an R squared value of 0.839 indicating the fit of the curve.Relationship between cement content and liquid limit (after Khalid et al., 2019)
