چکیده انگلیسی
The durability and safety of cement-treated foundation in marine environment has been drawn close attention because many offshore, coastal and marine engineering are under construction in these years. Effect of compound nano-CaCO3 addition on strength development and microstructure of cement-stabilized soil in marine environment was studied in this paper by uniaxial compressive test and micro-structure analysis methods including X-ray Diffraction Analysis (XRD), Scanning Electron Microscopy (SEM) and Mercury Intrusion Porosimetry (MIP). Results showed that marine environment had great influence on the strength and durability of cement-stabilized soil and compound nano-CaCO3 addition could effectively improve the compressive strength of cement-stabilized soil at early and late age due to the nucleation and nano-filling function. Furthermore, compound nano-CaCO3 addition was helpful to reduce the corrosion speed and increase the compaction degree of cement-stabilized soil in marine environment.
