Compressibility of cement-admixed clays at high water content

The compressibility characteristics of cement-admixed clay are an important issue for the deformation analysis of composite soft clay. This paper attempts to analyse and assess the compressibility characteristics of cement-admixed clay. It has been found that cement content is the prime parameter governing the compression curve at post-yield state. The generalised compression line is newly developed for uncemented and induced cemented clays. The compression curve of cement-admixed clay can simply be predicted by employing this generalised compression line together with initial void ratio and yield stress. The prediction method is useful not only for quick determination of compression curve with acceptable error, but also for examination of the test results.
