Lime is environmentally friendlier than cement. This study was performed with the aim of finding the suitability of lime and lime-cement combinations as the stabilizer for CSEB production with reduced clay and silt contents. The soil selected for this study was modified to obtain clay and silt contents of 5 %, 10 %, and 15 %.

This chapter outlines the testing of clays for civil engineering purposes in the laboratory. The laboratory may range from a large permanent establishment to a small temporary facility set up on site. Field tests (or in situ tests), which are carried out on clay while it is still in the ground, are covered in Section 7.6.

Soils are generally sampled by driving a sampling tube into the soil, usually to 10cm depth, and extracting a soil core. To obtain a representative sample, soil cores are combined from a large number of places within the sample area. The more cores that are combined, the more representative the final sample is and more accurate advice can be …
