Effect of loading rate change on the mechanical properties of mudstone under uniaxial compression
To study the effect of the loading rate change on the deformation and strength properties and creep behavior of mudstone, a series of uniaxial compression tests and graded loading creep tests was conducted on mudstone specimens at four loading rates (0 ...

Dominant performance parameter and technical limits of surfactants for oil displacement
In chemical flooding, emulsification and interfacial tension (IFT) reduction are crucial for enhanced oil recovery (EOR). However, the dominant performance parameter and technical limits of surfactants for oil displacement remain underexplored.

Study of Dynamic Modulus of Asphalt Mix after Reinforcement of Sandstone
Sandstone has poor mechanical properties. To facilitate the application of sandstone into asphalt mixtures, sandstone was treated by immersion in sodium silicate solution, and the dynamic modulus after reinforcement was used as a criterion.
