Abstract
The aim of this study is to provide a comprehensive analysis of the strength development of dredged soil stabilization with different grain sizes of basic oxygen furnace (BOF) slag. Laboratory vane shear (LVS) tests, unconfined compressive (UC) strength tests, and flow value tests were conducted to understand the time-strength behavior of stabilized dredged clay. The results show that the strength was significantly affected by the different maximum particle sizes, despite the same free lime content. An equation to predict the strength development of a larger maximum grain size from a smaller maximum grain size was proposed using a modified BOF slag rate of addition and its calculated specific surface area. The results indicate that the equation is feasible for predicting the strength development of actual construction from laboratory test results.
