Extending the service life of structures is an important strategy to mitigate the environmental
impacts, in particular, the global warming potential, of the building sector. As a key factor …

Shotcrete is often used to repair overhead and vertical concrete surfaces. However, the
material mismatch between the concrete substrate and shotcrete overlay makes the …

In this paper, a novel approach is proposed to determine target reliability index based on
modeling performance degradation of concrete structures as a stochastic process. First, the …

Hydraulic concrete structures in cold regions are vulnerable to freeze–thaw (FT) damage,
which will affect the fracture performance of concrete structures. Hence, the fracture …

This paper investigates the effect of the binary combination of nano-alumina (nano-Al₂O₃)
and nano-titanium dioxide (nano-TiO₂) on the mechanical properties of concrete. Although …

In order to study the uniaxial compressive damage characteristics and stress–strain
behavior of concrete with different degrees of freeze–thaw (FT) damage, and then effectively …

Understanding the evolution of mechanical properties and microscopic pore structure of
concrete after freeze–thaw cycles is essential to assess the durability and safety of concrete …

Studies show the temperature field inside the concrete under freeze‒thaw cycling is not
uniformly distributed. However, the existing indicators of freeze‒thaw damage do not take …

The deterioration of concrete microstructures in freeze–thaw (F–T) cycles is the primary
reason for the reduction in the service life of concrete. This paper reviews recent progress in …

As a nondestructive imaging technology, X-ray CT has become an effective tool for studying
the microstructural damage of concrete. However, autonomous identification and …
