Figure 7.
The graph depicts the relationship between the void index, labelled as I v, on the Y-axis and effective vertical stress, labelled as s v, on the X-axis, ranging from 1 kilopascal to 10000 kilopascals. It includes multiple curves corresponding to cement content of 1 percent, 2 percent, and 3 percent. The data points are differentiated by cutting orientation, with distinct markers for vertically cut and horizontally cut samples, each labelled with the associated effective stress values. The plot depicts a downward trend, where higher effective vertical stress corresponds to lower void index values. The legend provides detailed information for each data series, including cement content and effective stress values.Iv-log σ′v curves of lightly cemented kaolin with vertically and horizontally cut specimens and initial water content at 2.0wL
