Expansive slurry has attracted more and more attention because it can compensate for the
reduction of the grouting reinforcement effect caused by dry shrinkage of cement, but the …

Geosynthetics have been applied in various engineering fields. This study investigates the
shear strength of a two-layer geotextile reinforced with a flowable fill. Three types of …

An expandable foam grout (EFG) is developed to fill underground cavities. The objective of
this study is to evaluate the volume, strength, and stiffness of the EFG during curing using …

This study explores a novel application of Polyurethane Foam Adhesive (PFA) injection to
augment shear resistance at the interface, investigating various parameters such as PFA …

Foam cement is an engineered lightweight material relevant to a broad range of engineering
applications. This study explores the effects of aluminum chips on cement-bentonite slurry …

Underground cavities induced by damaged slurry walls or soil erosion in urban areas
require suitable repair materials and methods. The objective of this study is to evaluate the …

A split grouting-reinforced body (SGRB) is the new surrounding rock that forms after split
grouting reinforcement in tunnels and underground engineering, and its shear-seepage …

The conventional direct shear apparatus has been widely used to analyze the shear
behavior of the soil-soil and soil-solid interfaces. However, it has certain limitations, such as …

Biopolymers have recently been used as ecofriendly materials for soil improvement in terms
of stabilization, compressibility, and engineering parameters. The objective of this study is to …

Highly porous cementitious materials have been utilized in various geotechnical
