Effects of Sodium Sulfate Attack on Concrete Incorporated with Drying‐Wetting Cycles [PDF]
Advances in Civil Engineering, 2021 It has been widely observed that sulfate attack can damage the durability of concrete. This research investigated the mass loss and damage degree of concrete under sodium sulfate attack incorporated with drying‐wetting cycles. The impact factors, including water‐binder ratio, solution concentration of sodium sulfate, fly ash content, curing time, and ...

Permeability and Microstructure of a Saline Intact Loess after Dry‐Wet Cycles [PDF]
Advances in Civil Engineering, 2021 Influenced by both dry‐wet cycles and salt weathering, the loess will exhibit significant changes in microstructure and permeability, which threatens the stability of loess slopes. Triaxial permeability tests and industrial computed tomography (CT) scans were carried out on saline intact loess with sodium sulfate.
