Simulation of moisture variations in concrete during prolonged alternate wetting and drying cycles using 3D discrete network model

open access: yesCase Studies in Construction Materials, 2023
The precise prediction of moisture variations within concrete is of great significance because various deterioration phenomena spanning corrosion to carbonation are induced by mass transfer facilitated by the presence of moisture.

Influence of Dry-Wet Cycles on the Structure and Shear Strength of Loess

open access: yesSustainability, 2023
The dry-wet cycle is an important factor that causes slope instability and foundation settlement in loess regions. In order to study the effects of the dry-wet cycle on the structure and shear strength of loess, isotropic compression tests and triaxial shear tests were carried out on loess with different numbers of dry-wet cycles. The results show that
