Abstract: In this paper, a mechanical model and analysis method have been established to analyze the characteristics of casing-cement-formation of offshore wells in testing and production. The model, which can be simplified to a ...

Abstract: The sand replacement rate and fineness modulus of rubber particles are considered as variables in this study. The effects of the fine aggregate content and fineness of the rubber particles on the impermeability and frost-salt ...

Abstract: Heat-treated ribbed bar 630 (HTRB630) is a new type of reinforcing steel produced in China. The tensile properties and low-cycle fatigue properties of HTRB630 high-strength steel bars after exposure to high temperature are ...

Abstract: To explore the application of heat-treated ribbed bar (HTRB) type HTRB630 high-strength steel bars in reinforced concrete bridges, the tensile test and high-cycle fatigue test are carried out. Then, the high-cycle fatigue ...
