Abstract
Cemented soil structures are frequently exposed to the corrosive environment of seawater for an extended period, severely affecting their interior structure and mechanical qualities. This study presents laboratory-based approach to investigate the effect of nano-SiO2 on the structural and mechanical properties of cemented soil in a simulated seawater environment. The unconfined compressive strength (UCS), elastic modulus and other mechanical properties of cemented soil mixed with nano-SiO2 and ordinary silicate cemented soil were evaluated. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to deduce the crystalline composition and microstructure characteristics of the modified cemented soil. The results show that the addition of nano-SiO2 greatly increased the compressive strength and corrosion resistance of the cemented soil. In a 3C (105% salinity) simulated saltwater curing environment, the compressive strength of the cemented soil containing 2% nano-SiO2 increased by 86% and 158% at 30days and 60days, respectively. XRD and SEM showed that nano-SiO2 enhanced the interface structure of cemented soil and increased the compactness of the cement-soil system. The current study demonstrates that nano-SiO2 could considerably improve the mechanical characteristics and corrosion resistance of cemented soil when exposed to simulated seawater.
