Numerical and experimental investigation of coupled capillary suction and chloride penetration in unsaturated concrete under cyclic drying-wetting condition
TL;DR: In this paper , a mesoscale numerical modeling of chloride penetration coupled with capillary suction in unsaturated concrete exposed to cyclic drying-wetting condition is presented. But the results indicate that the established model can accurately predict the coupled transport of water and chloride in unstructured concrete under cyclic driewetting condition.

Freeze-thaw resistance of recycled aggregate concrete incorporating ferronickel slag as fine aggregate
TL;DR: In this paper , the coupling effects of different FNS and recycled concrete aggregate (RCA) contents to respectively replace fine aggregate (0, 20, 40, and 50%) and coarse aggregate ( 0, 50, and 100%) by equal weight on the frost resistance of concrete were explored.

A state-of-the-art review on high temperature resistance of lightweight aggregate high-strength concrete
TL;DR: In this paper , the damage evolution mechanisms of concrete at elevated temperatures were first summarized and introduced, and the influence of some factors, including lightweight aggregate types and dosage, replacement ratio, heating rate, and cooling system, on the mechanical and durability-related properties of LWA-HSC after high temperatures was further discussed, and strengthening mechanisms of the resistance to high temperature was elaborated and analyzed.
