a r t i c l e i n f o The purpose of this study is to investigate the role of filling materials (e.g., quartz sand and kaolin clay) in the interaction between a P-wave and a rock fracture. The specific fracture stiffness reflects the seismic response of a filled fracture, while the wave transmission coefficient describes P-wave transmission across the filled fracture. A series of experimental t...

Electrokinetically enhanced in-situ flushing using surfactants has the potential to remove polycyclic aromatic hydrocarbons (PAHs) from low permeability clay soils; however, previous research has shown that the applied electric potential produces complex physical, chemical, and electrochemical changes within clay soils that affect mass transfer and overall efficiency. This article presents the ...

Abstract Kaolin samples were collected to study the mineralogical, texture, chemical composition, thermal behavior, and treatment also possibility convert kaolinite mineral into metakaolin use it as a natural pozzolanic and/or geopolymer materials. Kaolinite is main constituent of clay mineral, which related many weathering parent rocks complete leaching alkali elements under warm, humid semi-a...

<p>Plasticine is an artificial material made from solids such as gypsum, lime, mixed with petroleum jelly or micro wax and acid fat. The properties of plasticine are likely similar to natural clay influenced by oil content. information about mechanical still very rare, the study on it riquired must be conducted intensively. preliminary laboratory has been understand behaviour plasticines....

Although there are several studies indicating that heating increases the long-term shaft resistance of energy piles, mechanisms by which causes this increase have not been adequately evaluated yet. This article presents a comprehensive analysis and discussion to assess important factors contributing integrating findings from three recently published papers studying thermo-mechanical behavior cl...
