Abstract [en]

The procedures used for the preparation and curing of stabilised specimens in the laboratory can affect the properties measured in various tests. The influence of different laboratory procedures should be known when comparing results from laboratories using different standards or procedures. The influence of laboratory procedures must also be known when deviating from the normal procedures, in cases where the materials are difficult to compact, where prolonged preparation times are involved, or when other curing temperatures are used in order to accelerate curing or to reproduce temperatures in the field. As part of a larger international study, the influence of different laboratory procedures for the preparation and curing of stabilised specimens has been studied in series of tests on cement and cement-lime stabilised organic soils. The effects of different moulding methods, different delay times before moulding, and different curing temperatures on the strength, density and water content have been studied. Some influence of the procedures used was observed in all three aspects of the procedures studied. Although limited in the cases studied, these effects should be considered when analysing results from laboratory stabilisation tests.
