Stabilization of residual soil using SiO2 nanoparticles and cement

Stabilization of residual soil using SiO2 nanoparticles and cement

An experimental study was performed to determine the effect of SiO2 nanoparticles on consistency, compaction, hydraulic conductivity, and compressive strength of cement-treated residual soil. Also, SEM, XRD and FTIR tests were carried out to identify the underlying mechanisms. The addition of nanopa...
