Due to the rapid growth of nanotechnology, many researchers from the field of science and
engineering have expressed a keen interest to extend the research in this field. Soil is a …

In the booming field of nanotechnology, colloidal silica (CS) has been introduced for ground
improvement and liquefaction mitigation. It possesses a great ability to restrain pore …

Fragmental size of broken rock mass has a significant effect on silica sol grouting regularity.
Firstly, the relationship between porosity, permeability and variable fragmental size of Case …

Grouting is an important process for stability control of unfavourable geology. A multi-
parameter grouting monitoring device was designed to monitor pump pressure, inlet density …

The main objective of the current research is to study the dynamic behaviour of colloidal
silica treated grout. The treatment of foundation soil with colloidal silica improves the cyclic …

Passive site stabilization is a developing technology for the in situ mitigation of the risk of
liquefaction without surface disruption. It involves the injection of stabilizing materials into …

Liquefaction mitigation in already existing sites has become a cause of concern for
geotechnical engineers across the world. One of the possible solutions for such sites is the …

Low–concentration of colloidal silica (usually from 5 to 20 wt%) for liquefaction mitigation
has been widely studied. But fewer literatures have focused on higher concentration of …

Colloidal silica can quickly seep through sand and then form silica gels to cement sand
particles. To improve the strength of sand seeped by colloidal silica, carbon nanotubes were …

Traditional grouting materials (such as cements, sodium silicates and organic polymers etc.)
have some limitations in improving soil, the rheological property of cement-based slurries is …
