Abstract: Foamed phosphogypsum (FPG) has recently attracted extensive interest owing to its potential consumption of phosphogypsum and its substitution for traditional gypsum building materials. However, as an important component ...

Abstract: By developing a hierarchical modeling method, using discrete element analysis software PFC3D, a discrete-element method (DEM) model can be built and solved more efficiently. In this method, smaller particles are used for ...

Abstract: This paper describes the findings of a study of the soil plugging progressive formation process during pipe pile penetration using a transparent soil model test. The objective of this study is to visually investigate the ...

Abstract: A novel chlorine- and fluorine-free liquid accelerator was developed in this study. The proportion of each component of the accelerator was determined using an orthogonal test method. Various additives’ impact on the cement ...

Abstract: For the purpose of understanding the mechanism that results from treating expansive soil with lime, a series of tests were conducted on selected Nanyang expansive clay. X-ray diffraction tests indicated that the major clay ...

Abstract: Mechanical properties and deformation behaviors of methane hydrate are important to assess the stability of gas hydrate reservoirs. In this study, using a high-pressure and low-temperature triaxial testing apparatus, the ...
