Cone penetration tests (CPT) and more recently piezocone tests (CPTU) have been used in geotechnical practice for a number of years. However, most of the geotechnical literature and available interpretation methods for the test results are for 'text book' soils, i.e. pure clay and pure sand. There is an increasing tendency now to also use CPT and CPTU more and more in other soils and materials. It is, therefore, important to know how to interpret the test results in the most meaningful way in these other materials. This paper considers practical examples of the use of CPT and CPTUs in a range of non-textbook materials including: intermediate, partly drained soils in the silt range; peat/organic soils; underconsolidated clays; soft rock including chalk; and mine tailings.
