外文摘要：With the increasing popularity of stabilizing soft soils by a cementitious binder, accurate strength prediction of cemented clay with curing period is essential for quality control. In this study, a generalized hyperbolic was proposed to overcome the shortcomings of traditional logarithmic function with regard to both short-term and long-term prediction of strength development. Also, the generalized formula can be used for various cement types, soil types, and curing conditions. It was proved that the model works well for both Ordinary Portland cement (OPC) and Portland blast-furnace cement (PBFC) treated clay. Moreover, the model can also be adopted for stiffness prediction of cemented clay. Based on the proposed model, the predicted strength and stiffness of cemented clay shows high consistency with the measured data from previous literature. (C) 2018 Elsevier Ltd. All rights reserved.
