Dataset consists of:

1) Figure 1. Variations in the UCS-CaCO3 relationship of bio-cemented sand.
2) Figure 3. Compressive stress versus axial strain for all tested cores during UCS tests. 
3) Figure 5. Bulk density variation along slice number for thirteen full-length core samples and one 10 cm-long core sample (24B).
4) Figure 6. UCS values plotted against CaCO3 content and bulk density.
5) Figure S2. (a) X-ray transmission intensity versus slide number. (b) Comparison of bulk density determined by the traditional method and by 2D X-ray radiography.
